Sloane, T. O'Conor. As they absorb moisture, heat is produced, which is known as heat of absorption. In these machines, the refrigerant is absorbed-dissolved into another fluid (a hygroscopic fluid), reducing its partial pressure in the evaporator and allowing more liquid to evaporate. A hygroscopic cycle demonstration plant has been built, demonstrating the concepts of the cycle, which includes the absorption of vapour A hygroscopic substance is able to absorb or adsorb water from its surroundings. [1], If a compound dissolves in water, then it is considered to be hydrophilic.[2]. atitikmenys: angl. Differences in hygroscopy can be observed in plastic-laminated paperback book covers—often, in a suddenly moist environment, the book cover will curl away from the rest of the book. hygroscopic water Tightly held water on soil particle surfaces as a result of adhesion; this water is essentially unavailable to vegetation. Typically, this occurs at or near ordinary room temperature. Non-hygroscopic fluids (e.g. ability of a substance to attract and hold water. This water is stored in spaces between the soil particles and made available to the roots of the plant and small animals living inside the soil. Therefore, a substance which is hygroscopic is one which is able to consistently attract water from its surroundings via adsorption or absorption. Water also collects in these grooves when it rains. A hygroscopic substance tends to absorb moisture from the air. 2 words related to hygroscopic: absorbent, absorptive. Many of them react chemically with water such as hydrates or alkaline metals. Hygroscopic water is a specific type of bound/held water . water evaporates, i.e. Jump to navigation Jump to search. The hygroscopic cycle has been introduced in a biomass power plant in the province of Cordoba, Spain. Soil water is the term for water found in naturally occurring soil. Soil water is the term for water found in naturally occurring soil. The salts are desorbed in the boiler or steam generator, where clean steam is released and superheated in order to be expanded and generate power through the steam turbine. Hygroscopic compounds are all those substances that attract water in vapour or liquid from their environment, thus their use as desiccant. Such materials were then said to be hygroscopic because they were suitable for making a hygroscope. Increased moisture causes it to untwist, and, upon drying, to twist again, thereby drilling the seed into the ground. File:Hygroscopic water.png. Many engineering polymers are hygroscopic, including nylon, ABS, polycarbonate, cellulose, and poly(methyl methacrylate). (of a substance) absorbing water from the…. The amount of moisture held by hygroscopic materials is usually proportional to the relative humidity. The owner of the plant can now reach all the generation premiums of this plant. Noun .

Related terms . hygroscopic; Translations . ), and a wide variety of other substances. This is the first industrial reference of this technology. Achieve … A hygroscopic material will tend to become damp and cakey when exposed to moist air (such as the salt inside salt shakers during humid weather). Given that the concentration of salts increases, the boiling point temperature of the mixture of salts is affected. Hygroscopic Salts - Designing Buildings Wiki - Share your construction industry knowledge. Boiler blowdown with the concentrated hygroscopic compounds is used thermally to pre-heat the steam turbine condensate, and as reflux in the steam-absorber. 2013. Most hygroscopic materials are salts, but many other materials display the property. Nonhygroscopic definition is - not readily taking up and retaining moisture : not hygroscopic. Fertilisers added to the soil also dissolve in this hygroscopic water and are absorbed by the roots of the plants. Wikipedia . The effect of this is that a steam turbine with a lower outlet pressure can be used, with a lower enthalpy level at the outlet of the turbine. But the word hygroscopic (tending to retain moisture) lived on, and thus also hygroscopy (the ability to do so).

The air-cooler used in the hygroscopic cycle cools a liquid flow with concentrated hygroscopic compound, with an overall volumetric heat capacity much higher than the steam traditionally condensed in air cooled condenser mentioned earlier, thus reducing the power needed for ventilation, and needing less surface area for heat exchange and obtaining a lower overall cost of the plant.[3]. Materials and compounds exhibit different hygroscopic properties, and this difference can lead to detrimental effects, such as stress concentration in composite materials. Nowadays an instrument for measuring humidity is called a hygrometer (hygro- + -meter). Here the outlet steam is absorbed by cooled hygroscopic compounds using the same principles as in absorption refrigerators. The preliminary results from Mexico are bolstering the findings from Africa, where investigators reported that flares containing water-absorbing, or hygroscopic, salts can significantly and reliably boost the amount of rain falling from clouds. Preshave products and some shave creams contain potassium hydroxide to force open the hair cuticle and to act as a hygroscopic agent to attract and force water into the hair shaft, causing further damage to the hair. Because of their affinity for atmospheric moisture, hygroscopic materials might require storage in sealed containers. Hygroscopic substances include honey, glycerin, ethanol, methanol, concentrated sulfuric acid, methamphetamine, and concentrated sodium hydroxide (lye). Proteins adsorb readily onto the surface of skin and hair and are generally hygroscopic, meaning they attract water molecules from the air to act as humectants. Facts Worth Knowing Selected Mainly from the Scientific American for Household, Workshop, and Farm Embracing Practical and Useful Information for Every Branch of Industry. The physical and chemical characteristics of the hygroscopic compounds, as well as their impact on the boiler, and other main equipment of the cycle similar to those found in thermoelectric plants have also been proven, together with the overall thermodynamic efficiency of the cycle. The Hygroscopic cycle has allowed the plant to cut the cooling consumption for these air coolers, increase the power output by 1%, and increase the availability all around the year. Hartford: S. S. Scranton and Co. 1895. Antonyms for hygroscopic. Potassium hydroxide is used to identify some species of fungi. Other polymers, such as polyethylene and polystyrene, do not normally absorb much moisture, but are able to carry significant moisture on their surface when exposed to liquid water. Here’s what to know before you cut it.," 5 Oct. 2020 These hydrogels have also been used for absorption— hygroscopic … atitikmenys: angl. hygroscopic (comparative more hygroscopic, superlative most hygroscopic) ( physics , chemistry ) Readily taking up and retaining water , especially from the atmosphere .

Hygroscopic substances include cellulose fibers (such as cotton and paper), sugar, caramel, honey, glycerol, ethanol, wood, methanol, sulfuric acid, many fertilizer chemicals, many salts (like calcium chloride, bases like sodium hydroxide etc. Thus by reducing the cooling water needed, the operating costs of the plant will be reduced. See more. With the appropriate salts, this can reduce, or even eliminate the consumption of cooling water in the power plant. hygroscopic; Translations . These hygroscopes used materials, such as certain animal hairs, that appreciably changed shape and size when they became damp. Hygroscopic definition is - readily taking up and retaining moisture. From French hygroscopie. The selection of hygroscopic salts have to provide the following strict criteria in order to be of interest of use in the hygroscopic cycle: Some of the most known salts with similar properties are Calcium chloride, Sodium Hydroxyde, sulfuric acid and Copper(II) sulfate. A hygroscopic substance is one that readily attracts water from its surroundings, through either absorption or adsorption. (of a substance) absorbing water from the air: 2. hygroscopy (uncountable) The ability of a substance to attract and hold water molecules from the surrounding environment. How to use nonhygroscopic in a sentence. In order to understand the nature of hygroscopic salts, we must first look at the term ‘hygroscopic’ which means to absorb water from the air. A soil is saturated when all soil pores are filled with water, which normally occurs after sufficient precipitation or irrigation. Structured data. As a result, the cooling is easier than in a conventional Rankine cycle in the condensation section by using an air-cooler to dissipate the heat of condensation in the refluxed concentrated hygroscopic fluid mentioned earlier. Wikipedia . The seeds of some grasses have hygroscopic extensions that bend with changes in humidity, enabling them to disperse over the ground. ik] (botany) Being sensitive to moisture, such as certain tissues. From Wikimedia Commons, the free media repository. Water held by soil under specific relative humidity and temperature conditions (usually 98% relative humidity and 25°C). Many of these compounds are hygroscopic . silicone/DOT 5 and mineral oil based formulations), are hydrophobic, and can maintain an acceptable boiling point over the fluid's service life. Cooling water circuits in power plants consume a high amount of fresh water[2] and chemicals, and their alternative, electric air cooled steam condenser consumes part of the power produced in conventional power plants, reducing the Rankine cycle efficiency.

In the hygroscopic cycle, the gas absorbed-dissolved into the other fluid is the steam coming from the outlet of the steam turbine. The Hygroscopic Cycle is a thermodynamic cycle converting thermal energy into mechanical power by the means of a steam turbine. [6], The use of different substances' hygroscopic properties in baking are often used to achieve differences in moisture content and, hence, crispiness. Hygroscopic is a property of a substance to absorb or adsorb water from its surrounding (one example of this would be dessicator type of compounds). Hygroscopy is the phenomenon of attracting and holding water molecules from the surrounding environment, which is usually at normal or room temperature. that is found to exist in all fine-grained soils, particularly clayey . This increase also helps the province to reach the COP 21 agreement.[6]. There are three main types of soil water - gravitational water, capillary water, and hygroscopic water - and these terms are defined based on the function of the water in the soil. It is a white, hygroscopic, water-soluble salt. Soil water is also called rhizic water. Hygroscopic water is formed by the water particles captured form the atmosphere and held by soil particles tightly. Not only is sulfuric acid hygroscopic in concentrated form but its solutions are hygroscopic down to concentrations of 10% v/v or below. Unlike any other -scopy word, it no longer refers to a viewing or imaging mode. within the plaster and within the wall itself near the apex of rise. Because of the thermal recovery of the boiler blowdown, the hygroscopic reaction in the steam condenser, and the use of an air-cooler to dissipate the heat of condensation, the efficiency of the cycle is higher, with a higher electrical output, reduces or eliminates the need for cooling water,[1] reduces the operating costs, and the capital cost of the utility power plant. hygroscopic water hygroskopisches Wasser n. English-german technical dictionary. Capillary water is the water content at field capacity minus the water content in air-dry soil, or hygroscopic water content. This dampness effect is entirely separate from that caused by capillary rise of water and is usually referred to as “hygroscopic” dampness. This means that the temperature of the concentrated hygroscopic fluid entering the absorber can be higher than a non hygroscopic fluid. Hygroscopy also plays an important role in the engineering of plastic materials. This is achieved through either absorption or adsorption with the adsorbing substance becoming physically changed somewhat. secobarbital powder is said in Wikipedia to be hygroscopic, and a bunch of us have tried to dissolve 10 gm of the powder in water and find that it gums up -- which I guess is why it's said to be hygroscopic, but does it eventually dissolve (you'd think we'd try; there are reasons we haven't) or should we dissolve in something else, e.g., whiskey? It is similar to the Rankine cycle using water as the motive fluid but with the novelty of introducing salts and their hygroscopic properties for the condensation. Hygroscopic water is formed by the water particles captured form the atmosphere and held by soil particles tightly. The Hygroscopic Cycle is a concept that has evolved recently and is at the heart of intensive research on hygroscopic fluids. Zinc chlorideand calcium chloride, as well as potassium hydroxideand sodium hydroxide(and many different salts), are so hygroscopic that they readily dissolve in the water they absorb: this property is called deliquescence. Hygroscopy is the phenomenon of attracting and holding water via either absorption or adsorption from the surrounding environment, which is usually at normal or room temperature. Clay holds more hygroscopic water than sand. Hygroscopic substances include cellulose fibers (such as cotton and paper), sugar, caramel, honey, glycerol, ethanol, wood, methanol, sulfuric acid, many fertilizer chemicals, many salts (like calcium chloride, bases like sodium hydroxide etc. This is similar to the function of a thermostat's bimetallic strip. File; File history; File usage on Commons; File usage on other wikis; No higher resolution available. For the underwater optical device, see, Phenomenon of attracting and holding water molecules, "Deliquescence" redirects here. It did begin that way, with the word hygroscope referring in the 1790s to measuring devices for humidity level. The water retained by this force is called hygroscopic water and it consists of the water held within 0.0002 millimeters of the surface of soil particles. Hygroscopic compounds are all those substances that attract water in vapour or liquid from their environment, thus their use as desiccant. As the steam is absorbed, the concentration of the hygroscopic fluid decreases, or the salt is diluted. ), and a wide variety of other substances. The water content of hygroscopic pharmaceutical products is affected by the water content of the surrounding air. A desiccant is a hygroscopic substance that is used to induce or sustain a state of dryness (desiccation) in its vicinity; it is the opposite of a humectant.Commonly encountered pre-packaged desiccants are solids that absorb water.Desiccants for specialized purposes may be in forms other than solid, and may work through other principles, such as chemical bonding of water molecules. Water is an important solvent, so it's unsurprising that there is a term specifically related to water absorption. Possessing a marked ability to accelerate the condensation of water vapor; applied to condensation nuclei composed of salts which yield aqueous solutions of a very low equilibrium vapor pressure compared with that of pure water at the same temperature. The salts are concentrated in the boiler, as steam is disengaged from liquid water. Noun . Descriptive terms of water availability are: saturation, field capacity, wilting point, and hygroscopic coefficient.Although there is some water chemically bound to minerals in soils, the water of significance to us is found in the soil's pore space. Non-hygroscopic fluids (e.g. Many of them react chemically with water such as hydrates or alkaline metals. Compare CAPILLARY MOISTURE. hygroscopic water. Source for information on hygroscopic water: A Dictionary of Earth Sciences dictionary. Sugars such as honey, brown sugar, and molasses are examples of sweeteners used to create more moist, chewy cakes. Learn how and when to remove this template message. hygroscopic water: translation that water in the soil which exists as a microscopic level as a layer around particle of clay. The Hygroscopic Cycle is a thermodynamic cycle converting thermal energy into mechanical power by the means of a steam turbine. The unlaminated side of the cover absorbs more moisture than the laminated side and increases in area, causing a stress that curls the cover toward the laminated side. Etymology . Eventually, though, the word hygroscope ceased to be used for any such instrument in modern usage. From the Cambridge English Corpus On the other hand, this hygroscopic ability would mean vulnerability for exposure to liquid water. In this weakened state, the hair is more easily cut by a razor blade. Deliquescence, like hygroscopy, is also characterized by a strong affinity for water and tendency to absorb moisture from the atmosphere if exposed to it. Some plastics are hygroscopic while others are not. Learn more. How to use hygroscopic in a sentence. It results from the interactive forces between fibre molecules and water molecules. The plant was being forced to reduce its production due to water restrictions during high temperatures in the region (the plant consumed 1200 m3/day using adiabatic air coolers from 25 °C onwards of ambient temperature). Others trap water as water of hydration in their crystalline structure, such as sodium sulfate. The plant can now operate at 38 °C, and even 45 °C ambient temperature. Calcium chloride is so hygroscopic that it eventually dissolves in the water it absorbs: this property is called deliquescence (see below). higroskopinis vanduo statusas T sritis chemija apibrėžtis Higroskopinės medžiagos iš oro sugerta drėgmė. Different varieties of sugars are used in different quantities to produce a crunchy, crisp cookie (UK: biscuit) versus a soft, chewy cake. For the album by Swans, see. Soil water is also called rhizic water. The word hygroscopy (/haɪˈɡrɒskəpi/) uses combining forms of hygro- and -scopy. Hygroscopic water is held very tightly on the surfaces of soil particles. FYI...a hydroscope is a sort of microscope used to look into deep water. What are synonyms for hygroscopic? A hygroscopic substance is one that readily attracts water from its surroundings, through either absorption or adsorption. In most salts, this will increase the boiling point temperature, and the steam temperature that is disengaged.[4]. Antonyms for hygroscopic. It is similar to the Rankine cycle using water as the motive fluid but with the novelty of introducing salts and their hygroscopic properties for the condensation. Click on a date/time to view the file as it appeared at that time. For the last two cases, water can be easily desorbed in a reversible way, as opposed to the first case, where water cannot be recovered easily (calcination may be required). Recent Examples on the Web The term often used to describe sugar’s ability to attract water is hygroscopic. The following compounds are liquid at room temperature and are completely miscible with water; they are often used as solvents. Recent developments have been the Kalina cycle,[7] but with the actual configuration, it is expected to have an impact in locations with poor access to water, and a good integration with combined cycle plants, and any thermoelectric plants (CSP, biomass, coal). In other words, the deliquescent fluid can condense vapor at a higher temperature. What are synonyms for hygroscopic? In the steam absorber, steam is absorbed with a concentrated hygroscopic fluid. An example is Needle-and-Thread, Hesperostipa comata. Chapter 7 Measurements of soil water From French hygroscopie. ability of a substance to attract and hold water. Inexpensive dial-type hygrometers make use of this principle using a coiled strip. Adjective hygroscopic (comparative more hygroscopic, superlative most hygroscopic) (physics, chemistry) Readily taking up and retaining water, especially from the atmosphere. Hygroscopic textile fibres absorb water vapour according to their chemical composition and structure. The true term is "hygroscopic" and it refers to a material or solution that readily uptakes moisture from the atmosphere. The Hygroscopic Cycle is a thermodynamic cycle converting thermal energy into mechanical power by the means of a steam turbine. All the information in our site are for educational uses. Infiltration and soil water storage. Hy­groscopy is the phe­nom­e­non of at­tract­ing and hold­ing water mol­e­cules from the sur­round­ing en­vi­ron­ment, which is usu­ally at nor­mal or room tem­per­a­ture. Most deliquescent materials are salts, including calcium chloride, magnesium chloride, zinc chloride, ferric chloride, carnallite, potassium carbonate, potassium phosphate, ferric ammonium citrate, ammonium nitrate, potassium hydroxide, and sodium hydroxide. On the other hand, the hygroscopic materials absorb the water from its surrounding environment and consume enough to clomp together. Hygroscopy is the phenomenon of attracting and holding water molecules via either absorption or adsorption from the surrounding environment, which is usually at normal or room temperature. r in an absorber where hygroscopic compounds are recirculated, obtaining condensations with temperatures higher than the saturation temperature. Glycol-ether (DOT 3, 4, and 5.1) brake fluids are hygroscopic (water absorbing), which means they absorb moisture from the atmosphere under normal humidity levels. Hygroscopic / deliquescent fluids with a high dilution capacity in water, such as LiBr usually also show a high saturation temperature / low saturation pressure. This increases the efficiency of the turbine, and generates a higher electrical output. Hygroscopic Salts and Rising Dampness The Salt Problem When dampness has been rising in a wall for some time, the soluble salts contained in the ground become concentrated where the water evaporates, i.e. Depending on the salts chosen, in particular those with a high dilution capacity (i.e. Deliquescence is the process by which a substance absorbs moisture from the atmosphere until it dissolves in the absorbed water and forms a solution. hygroscopic water higroskopinis vanduo statusas T sritis chemija apibrėžtis Higroskopinės medžiagos iš oro sugerta drėgmė.atitikmenys: angl. within the plaster and within the wall itself near the apex of rise. Hygroscopy is the phenomenon of attracting and holding water molecules from the surrounding environment, which is usually at normal or room temperature. In order to understand the nature of hygroscopic salts, we must first look at the term ‘hygroscopic’ which means to absorb water from the air. Owing to their very high affinity for water, these substances are often used as desiccants, also an application for concentrated sulfuric and phosphoric acids. Zinc chloride and calcium chloride, as well as potassium hydroxide and sodium hydroxide (and many different salts), are so hygroscopic that they readily dissolve in the water they absorb: this property is called deliquescence.

When added to foods or other materials for the express purpose of maintaining moisture content, such substances are known as humectants. As the steam is absorbed-dissolved into the hygroscopic fluid, more steam can condense, and the reduction in vapor pressure is equivalent to a reduction in the condensation pressure at the outlet of the steam turbine. While some similar forces are at work here, it is different from capillary attraction, a process where glass or other solid substances attract water, but are not changed in the process (e.g., water molecules do not become suspended between the glass molecules).
