Abstract:
1. A method for processing a low pressure gas inlet stream to recover C2 and higher weight hydrocarbons, comprising the steps of dehydrating said low pressure gas inlet stream, cooling said low pressure gas inlet stream to form a partially condensed hydrocarbon feed, separating a first liquid stream and a first vapor stream from said partially condensed hydrocarbon feed, compressing said first vapor stream, separating said first liquid stream into a first part and a second part, using said first part of said first liquid stream in an absorber to absorb C partially condensing a top product from said absorber, separating said partially condensed absorber top product into a second liquid stream and a second vapor stream, separating a bottom product from said absorber into a first part and a second part, heating said first part of said bottom product, distilling said heated first part of said bottom product in a distillation column, utilizing said second part of said first liquid stream, said second liquid stream, and said second part of said bottom product as a top feed to said distillation column, and recovering C
