UK-based construction and civil engineering company, Costain has bagged two service contracts for Total’s Lindsey oil refinery at Immingham on the Humber Estuary in Lincolnshire, England.

The two engineering and procurement services contracts will help Total to further enhance the environmental performance of the refinery. Financial terms of the contracts were not revealed.

The Lindsey refinery processes about 200,000 barrels of crude oil per day and produces approximately 35 types of product.

Under the first contract, Costain will install a flare gas recovery compressor on the facility’s flare system to recover the gas and use it rather than emit it out in the atmosphere and pollute the air with carbon dioxide and sulphur dioxide.

Re-using the gas will also decrease the requirement to import natural gas as fuel.

The new installation is scheduled to become operational in late 2014 and the project will also allow further flare gas recovery systems to be accommodated in the future.

Under the second contract, the firm will install a Freon replacement package on one of the cryogenic units at the refinery to meet the requirements of Montreal Protocol on Substances that Deplete the Ozone Layer.

The company will design and install a new refrigeration package to replace the use of Freon as a refrigerant with propane.

Costain is expecting the new installation will come online after the shutdown of the refinery is scheduled for September 2014.
