Abstract

Disclosed are systems and methods for processing gas produced from oil and gas reservoirs while removing mercaptans from the gas. Mercaptan-selective membranes are used to debottleneck known systems and methods by removing mercaptans from bottlenecked plant process steps including LPG fractionation and mercaptan sweetening. Hydrogen sulfide can be simultaneously removed by the membranes. Production of on specification LPG and sales gases can be increased.
