We were approached by Scottish Power to provide a Front End Engineering Design (FEED) and deliver detailed Engineering, Procurement, Construction and Project Management (EPCm) Services for the gas processing facilities and 40MW power plant at their site near Malton, North Yorkshire. The site is fed with sour (High H2S) gas from five existing onshore wells located in the Vale of Pickering.

The location of the site in the scenic Yorkshire countryside meant that planning conditions for noise, leaks and odours were very stringent. Costain gave special attention to minimizing the visual and environmental impact caused by the plant. This was achieved  through extensive landscaping to mask the site with verges and trees, painting buildings & equipment to blend into the countryside colours and placing structures at a deliberately low profile.

The site comprises a gas treatment facility and a power plant. We designed a gas processing facility which removes liquids and through heating and pressure reduction, allows the gas to meet hydrocarbon & water dewpoint specifications while also removing up to 1000 ppm of H2S, helping to reduce the environmental impact of gas combustion. The cleaned gas is fed to a gas turbine where it is used to generate electricity which is exported to the grid.
