Analysis of semi-solid “shoe polish” material in a refinery TGTU
Amine units, and to a lesser extent tail gas treating units (TGTUs), experience occasional “shoe polish” sludge contamination.
Manage contaminants in amine treating units—Part 2: Rich amine filtration, inlet separation and amine foaming
The installation and operation of suitable separation and filtration systems have become key components of virtually all process units, especially amine units.
Managing process contaminants in amine treating units—Part 1: Lean amine filtration
Installation and operation of suitable contaminant removal systems, such as filtration, coalescing and adsorption equipment, have become key components in amine units.
Improve LPG treating via advanced amine-solvent recovery technologies
