The new plant will be erected in Gwangyang, South Korea, producing SNG from coal and/or petcoke. The plant, with a nominal capacity of 500,000 metric tons per year of pipeline-ready SNG, will be brought into operation by end of 2013. It will be the first SNG plant in South Korea. The Linde Group’s Engineering Division will supply the complete technology chain of syngas treatment and conditioning, including sour shift, acid gas removal — featuring Linde Rectisol — and sulphur recovery. Haldor Topsøe will supply the complete methanation technology, TREMP, including conditioning of the product gas, to deliver SNG with a methane purity in excess of 98 percent.
