Diisopropanolamine solution aqueous

Application to Alkanolamine Solutions Aqueous alkanolamine solutions are widely used for the removal of H2S and C02 from gaseous streams, because they can reduce the concentration of H2S and C02 to low levels, even if the gas stream is at a low total pressure. The most commonly used alkanolamines are monethanolamine (MEA) and diethanolamine. However, diisopropanolamine... 

Simultaneous Mass Transfer of Hydrogen Sulfide and Carbon Dioxide with Complex Chemical Reaction in an Aqueous Diisopropanolamine Solution... 

Solvents used for hydrogen sulfide absorption include aqueous solutions of ethanolamine (monoethanolamine, MEA), diethanolamine (DEA), and diisopropanolamine (DIPA) among others ... 

The simultaneous absorption of H2S and CO2 into aqueous 2.0 H diisopropanolamine (DIPA) solutions is studied both experimentally and theoretically. 

A minor variant to the amine scrubbing process described above is the Sulfinol process, which still uses an alkanolamine base, diisopropanolamine (35%), but in a solvent consisting of a mixture of sulfolane (40%), tetramethy-lene sulfone (CH2)4S02, a good hydrogen sulfide solvent) and water [29]. Other processes are based on hydrogen sulfide absorption in aqueous alkaline carbonate solutions, such as the Catacarb and Benfield systems (Eqs. 9.16 and 9.17). 

This case is similar to that of reaction 1 absorption of A followed by reaction with B in the liquid phase, with the difference that there are now two gases Ai and A2. Typical industrial examples are the reactions of CO2 and H2S with aqueous solutions of diglycolamine and diisopropanolamine, and of isobutylene and butenes with aqueous sulfuric acid. 

ADIP [Possibly an acronym of DIPA, diisopropanolamine] A process for removing hydrogen sulfide, mer-captans, carbonyl sulfide, and carbon dioxide from refinery streams by extraction into an aqueous solution of diisopropanolamine or methyl diethanolamine. Developed by Shell and licensed by Shell Global Solutions International BV. More than 400 units were operating in 2000.
