초록 ▼

An improved ethane recovery system and process which increases the recovery of ethane up to about 99% with no increase in plant residue compression horsepower. The improved ethane recovery process employs an additional fractionation column which receives two vapor streams in different regions thereo

대표청구항 ▼

[ I claim:] [1.] In an ethane recovery system, an apparatus comprising:separating means constructed to receive a cooled natural feed gas stream, said separating means dividing the cooled natural feed gas stream into an upper vapor stream and a lower liquid stream;dividing means connected to said separating means and receiving said upper vapor stream therefrom, said dividing means dividing the vapor stream into three streams, a first, a second, and a third vapor streams;distilling means located downstream from said separating means and said dividing means, said distilling means providing a bottom ethane product stream and an upper methane residue gas stream, said distilling means being connected to said separating means and receiving said lower liquid stream in a middle region of said distilling means, said distilling means further receiving said first vapor stream from said separating means in an upper mid-section region thereof;fractionating means connected to said separating means and to said distilling means , said fractionating means receiving said second and third vapor streams for separating methane therefrom and providing a bottom stream as a top reflux to said distilling means.
