LPG Vapor Recovery

Project Description

Shell Gas in Sweden (nowadays Kosan Gas) supplies Liquid Petroleum Gas (LPG) to industrial customers in the European Nordic countries Denmark, Norway, Sweden and Finland. At one of their LPG storage facilities in Göteborg, Sweden, a Vapor Recovery Unit had to be installed to convert the gases in the main storage tank, as a result of loading trailers with gas containers, back to LPG again.

For this Vapor Recovery installation, CSH supplied a skid mounted compression solution with two vertical mounted reciprocating compressors.
