Amine gas plant at a natural gas field. Amine gas treating, also known as amine scrubbing, gas sweetening and acid gas removal, refers to a group of processes that use aqueous solutions of various alkylamines (commonly referred to simply as amines) to remove hydrogen sulfide (H 2 S) and carbon dioxide (CO 2) from gases.
In a recent study, it took 4 hours to for the air stripper to reach an equilibrium of efficiency in removing NH3-N elements, topping off at an 81.9% removal rate. Comparatively, only 30.7% of NH3-N elements were removed at 10 minutes, suggesting that removal of contaminants of water correlates with the amount of time spent air stripping. [5]
Stripping is commonly used in industrial applications to remove harmful contaminants from waste streams. One example would be the removal of TBT and PAH contaminants from harbor soils. [4] The soils are dredged from the bottom of contaminated harbors, mixed with water to make a slurry and then stripped with steam.
Chemists remove gases from solvents when the compounds they are working on are possibly air- or oxygen-sensitive (air-free technique), or when bubble formation at solid-liquid interfaces becomes a problem. The formation of gas bubbles when a liquid is frozen can also be undesirable, necessitating degassing beforehand.
The SHARON (Single reactor system for High activity Ammonium Removal Over Nitrite) wastewater treatment process is a combination of two already used nitrogen removing reactions. One process utilizes fast growing nitrifiers utilizing nitrification of ammonia to nitrite and Anammox which is the denitrification of nitrite to atmospheric nitrogen ...
The two main chemicals needed for the metabolism of anammox bacteria to function are ammonia and nitrite. Nitrate and nitrite are produced by microorganisms within wastewater treatment facilities as a result of sewage treatment. The chemical compound ammonia monooxygenase converts ammonia in wastewater into nitrite during the nitrification process.
What Kolff needed was a way to remove urea from the blood without stripping off all the other components the body needed. ... the company uses an enzyme to convert urea to ammonia, and a sorbent ...
The tower was used in the removal of tar and ammonia from raw coal gas by Gas Stripping. Gas was piped into the base of the tower, from where it rose to the top via a series of internal baffles over which water was sprayed from a header tank at the top of the tower, stripping the gas of coal tar and ammonia in the process. The liquid was ...
