What is DEPG solvent?
DEPG is a mixture of dimethyl ethers of polyethylene glycol (CH3O(C2H4O)nCH3 (n is. between 2 and 9) used to physically absorb H2S, CO2, and mercaptans from gas streams. Solvents. containing DEPG are licensed and/or manufactured by several companies including Coastal Chemical.
Is Selexol flammable?
SelexolTM was discovered to be a low toxic and flammable solvent in contrast to Rectisol® which may result to death upon inhalation.
Which physical solvent is best for acid gas removal?
Propylene carbonate is the primary solvent in the Fluor process where it is used mainly for the removal of CO2 from the sour gas. Fluor shows its best performance when treating high pressure gas streams containing high concentrations of acid gas. Propylene carbonate is noncorrosive and nonaqueous.
What is DEPG?
Natural Gas Sweetening The Selexol process uses Selexol solvent, a physical solvent made of dimethyl ethers of polyethylene glycol (DEPG),13 to selectively remove H2S/COS plus remove CO2 in bulk from gas streams. This process can also be used to remove and control mercaptan sulfur.
What is Flexsorb?
Description. FLEXSORB™ SE is is a sterically hindered amine proprietary to ExxonMobil Research and Engineering Company, useful for selective gas scrubbing. Monument Chemical Bayport, LLC. has been authorized by ExxonMobil Research and Engineering Company as a supplier of FLEXSORB™ SE for licensed users.
What is acid gas removal unit?
The acid gas removal unit (AGRU) is designed to remove the acidic components to meet sales gas sulfur and CO2 specifications. H2S must be removed to meet the sales gas specification of 4 ppmv, or ¼ grains per 100 scf of gas.
What is Oase solution?
OASE® purple removes carbon dioxide and hydrogen sulfide in natural-gas applications. OASE® white enables the treatment of gases containing hydrogen and/or carbon monoxide for applications such as ammonia, iron-ore and many more. OASE® blue is used for carbon capture and storage.
How do you get rid of sour gas?
The most common technologies for acid gas removal are cyclic, regenerable, solvent absorption processes. In these processes, a liquid solvent is counter-currently contacted with the syngas in an absorption tower to selectively remove the H2S and/or the CO2.
Why acid gas removal is important?
Acid gas removal (AGR) units play a key role in integrated gasification combined cycle (IGCC) power plants. In IGCC plants without CO2 capture, the primary objective of the AGR unit is to satisfy an overall sulfur emission target. Therefore, the main sulfur-containing component to be removed in the AGR unit is H2S.
What is Oase white?
OASE® white enables the treatment of gases containing hydrogen and/or carbon monoxide for applications such as ammonia, iron-ore and many more. OASE® yellow selectively removes sulfur components from natural gas as well as acid-gas enrichment (AGE) or tail-gas treatment (TGT) units.
