Onshore Gas Compression and Acid Gas Treatment Plant

Burlington Resources were the operator of a number of sour gas fields in the East Irish Sea, collectively known as the Rivers Fields (now operated by ConocoPhillips). Costain was engaged to provide a solution to process the gas from these fields, which contains significant levels of hydrogen sulphide.

145 MMSCFD Sour Gas and 700 Barrels Condensate Per Day

to be processed onshore

Removal of CO2, H2S and Mercaptans

Prior to tie-in with existing terminal

Costain produced a design for a new onshore facility to carry out the following functions:

  • Receive wet sour gas at up to 95 bar gauge and well head liquids through duplicated 24 inch ESD valves and a pig receiver
  • Separate the liquids
  • Remove pipeline solids in a gas filter and liquid filter
  •  Compress the gas to export pressure
  •  Sweeten by removing hydrogen sulphide and mercaptans
  • Meter the gas with ultrasonic flow meters
  • Forward to the existing North Morecambe Terminal for further processing to National Transmission Systems (NTS) specification
  • Receive utilities from the existing terminal. 

Costain developed the design through detailed engineering and carried out project management, procurement, construction and commissioning for the new terminal.
