How does DGA compare to MEA for gas treating?

DGA runs at higher solution strength, which means lower circulation rates and lower regeneration energy, plus lower vapour loss than MEA.

Yes — it removes carbonyl sulfide as well as H₂S and CO₂, an advantage over some amines.

What material of construction is used?

Carbon steel is standard; stainless steel is used for high-purity and E-GRADE service.

Diglycolamine (DGA)

CAS 929-06-6 C₄H₁₁NO₂

CAS number: 929-06-6
EC number: 213-195-4
Formula: C₄H₁₁NO₂
Molar mass: 105.14 g/mol
Appearance: Essentially colourless, slightly viscous liquid; faint amine odour; water-miscible.

Diglycolamine is a primary alkanolamine and the go-to acid-gas sweetening agent where high solution strength and low energy matter — also an electronics stripper and epoxy intermediate. Ehlinar sources standard and electronic grades.

Applications
