Mobil North Sea Ltd.`s Scottish Area Gas Evacuation (SAGE) plant at St. Fergus, Scotland, has been designed to process a broad range of contract gases. It is currently the only U.K. terminal capable of processing northern North Sea sour associated gas containing both H{sub 2}S and CO{sub 2}. A key element has been integration of fixed-bed processes for selective removal of COS and H{sub 2}S from the gas and liquid product streams. The result has been operating flexibility and significant capital savings. The terminal consists of two gas-processing trains that were completed in two phases. The first train, with capacity for processing 500 MMscfd of sweet gas from Beryl, was brought on-line in July 1992. The second phase, completed in March 1994, allowed sour gas from Brae to be treated. The paper describes these processes, sour gas drying, NGL purification, and gas sweetening.
