Johnson Matthey announces completion of first COG to LNG project

Johnson Matthey is pleased to announce the acceptance of its coke oven gas (COG) to liquefied natural gas (LNG) project with Xinkuang Hengkung near Yinchuan, China. The new plant, using Johnson Matthey’s technology licence, engineering, catalysts and technical services, produces LNG utilizing the offgas from their coke ovens and has been accepted by Xinkuang Hengkung on the basis of its technical performance following plant commissioning.  Xinkuang Hengkung is a major producer of coke with current capacity of over 1.3 million tonnes per year.

By using the proprietary CRG methanation process available through Johnson Matthey Davy Technologies (JM Davy), the plant is able to convert carbon oxides and hydrogen in the offgases from their coke ovens to methane which is subsequently liquefied to make a valuable energy product.  Xinkuang Hengkung confirmed their satisfaction with the performance of the technology in a recent signing ceremony.

The project is an important milestone for both companies as it is the first COG to LNG project to be completed using Johnson Matthey’s technology.  It is likely to be the first of many similar projects as coke oven operators can now use this proven advanced technology to produce LNG from what might otherwise be a waste stream.  Johnson Matthey has already signed contracts for several other COG to LNG projects through its JM Davy business.  In addition, the CRG technology has been licenced to six coal-based substitute natural gas (SNG) plants in China.
