Ionic types of NADES such choline chloride-citric acid-water (CCCA-H 2 O = 1:1:18, mole ratio) and choline chloride-malic acid-water (CCMA-H 2 O = 1:1:18, mole ratio) gave the highest yield of extracted curcuminoids, ca. 0.270±0.025 and 0.355±0.055 mg/g respectively for CCCA and CCMA. However, the final product of the extracted curcuminoids

2020-2-29 · Here some reason are described which are responsible for various problem on Dyeing or the problems associated with hard water on the fabric or Textile yarn. 1. Scale Formation in Boiler: Temporary hardness creates CaCO3 and Mg (OH)2 in a boiler and in time accumulates in the form of scale. a) Ca (HCO3)2 CaCo3 b) Mg (HCo3) MgCO3 + Co2 + H2O
The World Health Organization states that hard water may lead to cardiovascular disease . Different industries use water as a main source for processes, and for steam generation in the boiler. The textile industry, paper industry, sugar industry, dying industry, and beer industries are the main sectors that use water for steam generation.
Mark Crowther, Technical Director, Kiwa Gastec Last month we reported on a two year project in Leeds to investigate how hydrogen could be used for domestic and commercial heating in place of natural gas. Mark Crowther, technical director at Kiwa Gastec, makes the case for conversion. It's a well known fact that the Climate Change Act 
2021-3-16 · In my study I have found that the industry is using NaClO(sodium hypochlorite), HCl(hydrochloric acid), SMBS(sodium metabisulfite) and antiscalant to treat water before reverse osmosis is
Hard water is a common quality of water which contains dissolved compounds of calcium and magnesium and, sometimes, other divalent and trivalent metallic elements. Dissolved calcium and magnesium salts are primarily responsible for most scaling in pipes and water heaters and cause numerous problems in laundry, kitchen, and bath.
Temporary Hard Water. Temporary hard water is hard water that consists primarily of calcium (Ca 2 +) and bicarbonate (HCO 3-) ions.Heating causes the bicarbonate ion in temporary hard water to decompose into carbonate ion (CO 3 2-), carbon dioxide (CO 2), and water (H 2 O). The resultant carbonate ion (CO 3 2-) can then react with other ions in the solution to form insoluble compounds,
2021-3-14 · Soap consumption by hard water represents an economic loss to the water user. Sodium soaps react with multivalent metallic cations to form a precipitate, thereby losing their surfactant properties. Boiler scale, the result of the carbonate hardness precipitation, may cause considerable economic loss through fouling of water heater and hot water
2020-7-12 · The idea is to create high-pressure steam in the boiler and force it down the pipe, whereupon it can drive the water up another pipe to the surface. It is a commercial failure. The metal-working of the time cannot handle the high pressure; the steam condenses in the uninsulated tubes before it
