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.
Hydrogen sulfide is also a potent cellular toxin, blocking the cytochrome system and inhibiting cellular respiration. More water-soluble gases (e.g. chlorine, ammonia, sulfur dioxide, hydrogen chloride) dissolve in the upper airway and immediately cause mucous membrane irritation, which may alert people to the need to escape the exposure.
The medium used is typically an activated alumina compound impregnated with materials to handle specific gases such as hydrogen sulfide. Media used can be mixed together to offer a wide range of removal for other odorous compounds such as methyl mercaptans , aldehydes , volatile organic compounds , dimethyl sulfide , and dimethyl disulfide .
Hydrogen sulfide is a chemical compound with the formula H 2 S.It is a colorless chalcogen-hydride gas, and is poisonous, corrosive, and flammable, with trace amounts in ambient atmosphere having a characteristic foul odor of rotten eggs. [11]
A Halimeter is an instrument for measurement of the level of volatile sulfur compounds (VSCs) in the mouth.. Halimeter was introduced in the early 1990s as an adjunct method for determining halitosis (bad breath, oral malodor) levels, alongside human assessment of odor levels (the latter is considered the gold standard).
Pressure control (PC) is a mode of mechanical ventilation alone and a variable within other modes of mechanical ventilation. Pressure control is used to regulate pressures applied during mechanical ventilation. Air delivered into the patients lungs (breaths) are currently regulated by Volume Control or Pressure Control. In pressure controlled ...
Selexol is the trade name for an acid gas removal solvent that can separate acid gases such as hydrogen sulfide and carbon dioxide from feed gas streams such as synthesis gas produced by gasification of coal, coke, or heavy hydrocarbon oils. [1] [2] By doing so, the feed gas is made more suitable (less sour) for combustion and/or further ...
A pulmonary agent, or choking agent, is a chemical weapon agent designed to impede a victim's ability to breathe.Such compounds operate by causing a build-up of fluids in the lungs, which then leads to asphyxiation.
