Amine gas treating - Wikipedia

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. It is a common unit process used in refineries, and is also used in petrochemical plants, natural gas processing

deae amine in high pressure boilers

It is used as a neutralizing amine for boiler water, coatings, etc. Diethylaminoethanol (DEAE) is used as neutralizing agent and CO 2 scavenger in boiler water. The ideal vapor pressure and vapor-liquid distribution properties of DEAE make it the best choice for pH adjustment of process water.

In high pressure boilers, total dissolved solids concentration in the boiler water is critical. For these applications, a volatile scavenger is used that will not contribute solids to the boiler water. Some common amines are: morpholine, cyclohexylamine, and diethylaminoethanol (DEAE). 8.4 Filming Amines: Filming amines are compounds that

Welcome To Combined Cycle Journal

The pressure at which the LP boiler is operated is a key parameter in reducing the risk of FAC damage. As pressure is decreased, an increase in fluid-mixture specific volume results in an increase in velocity. For natural circulation HRSGs, this is especially true in circuits between the upper half of the evaporator tubes and the steam drum.
