Gas Processing

Improve contaminant control in amine systems

These guidelines illustrate what every process engineer should know about solvent contamination and loss for sour gas processing facilities

Most sour-gas processing facilities separate hydrogen sulfide (H2S) and carbon dioxide (CO2) from raw gas through chemical absorption using alkanolamines (or "amines"). The prime alkanolamines are: monoethanolamine (MEA), diethanolamine (DEA), methyldiethanolamine (MDEA), diisopropanolamine (DIPA), and diglycolamine (DGA). The amine processes are cyclical-involving both absorption and desorption steps-to reuse absorbents. Because these processes are closed loop, nonregenerable contaminants accumulate within the system and can cause reduced processing efficiencies and operational problems. Operational difficulties include: corrosion, foaming, solid deposition, losses of valuab
