The Linde Group and Haldor Topsøe, a market leading provider of integrated catalyst solutions, have been selected as technology suppliers for the syngas treatment and methanation unit of POSCO’s synthetic natural gas (SNG) plant.

The new plant will be erected in Gwangyang, South Korea, producing SNG from coal and/or petcoke

The POSCO SNG plant, with a nominal capacity of 500,000 metric tons per year (MTPY) 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%.

“As a world leading gases and engineering company we are proud to participate in this ground-breaking project to produce synthetic natural gas from coal,” said Dr Aldo Belloni, Member of the Executive Board of Linde AG.

“The SNG technology offers benefits in the conversion of energy, especially in coal-rich regions. Our technical solutions for syngas treatment are part of our comprehensive engineering expertise in the field of alternative fuel generation.”

The project is owned by POSCO of South Korea, one of the largest steel producers in the world, and is executed by POSCO Engineering and Construction, a premier and global general construction and engineering company.
