Front end design of LPG recovery
Costain consultants were tasked with finding an optimum solution for the recovery of LPG (propane and butane) and a C5+ fraction from a number of refinery fuel gas streams.
Challenges
90,000 tonnes/year LPG
design capacity
LPG recovery
from up to 10 refinery fuel gas streams
Successful FEED and EPC
execution
Costain carried out a process design study for the evaluation of options for recovering LPG followed by a Front End design study. The solution developed uses over 60 equipment items and incorporates a cryogenic turbo-expander and refrigeration cycle to provide the recovery required.
Following the performance during front end design and the suitability of the solution developed, Costain was awarded a contract by ChevronTexaco for the detailed design, procurement, project management and construction management of a Fuel Gas LPG Recovery Plant at its refinery.
