摘要：
An NGL recovery plant includes a demethanizer (7) in which internally generated and subcooled lean oil absorbs CO2 and C2 from a gas stream (11), thereby preventing build-up and freezing problems associated with CO2, especially where the feed gas has a CO2 treatment at ethane recoveries above 90% and propane recoveries of at least 99%.
