ABSTRACT:
Gas conditioning glycol and alkanolamine solutions are treated for removal of gases and emulsified oils by passing the solution through a separator apparatus including an elongated cylindrical pressure vessel having a settling compartment with a length to diameter ratio of at least 6.0. The level of the liquid to be treated is maintained at approximately the horizontal centerline of the vessel by an oil overflow weir which decants the separated oil layer from the carrier liquid. The oil layer flows into a reservoir and is discharged from the vessel under the control of a level-controlled motor operated valve. The oil-conditioning liquid interface is controlled by an adjustable weir in the vessel disposed downwstream of the oil reservoir. A gas collection dome is disposed over the oil reservoir and includes mist separator pads for separating condensed liquids entrained in the separated gas. The incoming feedstream is controlled to limit the viscosity to 8.0 centipoises and is retained in the settling compartment by non-stir baffles and the level control weir for a residence time of from five to sixty minutes.
