FEED, EPC & Commissioning of Power Plant & Gas Processing Facilities

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.

Stringent planning conditions covered noise at the main site, well sites and detection of pipeline leaks and odours. In addition, extensive treatment was given to the visual aspects of the plant - structures were deliberately low profile and landscaped.

Gas is conditioned by liquids removal in a three phase separator. The gas is heated and reduced in pressure to meet hydrocarbon and water dewpoint specification. Up to
1000 ppm of H2S is removed from the feedstock.

Electricity is generated by a gas turbine generator system and exported via a 132kV transmission line connected to the overhead grid. Power is provided by a RLM6000 gas turbine unit.
