JGC finalizes license agreement for sulfides in China

Gerald Ondrey

JGC Corp. (Yokohama, Japan; has signed a license agreement for its proprietary hydrogen sulfide and sodium sulfide production-process technology with Zhejiang Engineering Design Co. (ZED) in China, to serve as a proxy for licensing the technology to Chinese clients.

Hydrogen sulfide is used as a feedstock during production of sulfur-containing compounds. Demand has increased significantly, particularly in recent years, for use in the production of engineering plastic (PPS) and methionine. PPS has a high level of strength and heat tolerance, and is increasingly used in consumer electronics and electronic devices of all sorts. Methionine, an essential amino acid, is increasingly produced for use in poultry feed. Worldwide, the demand for PPS and methionine is expected to top Ŷ300 billion in the near future.

The process technology developed by JGC involves two reactions between sulfur and hydrogen, the first using heat, the second using a catalyst. Together, the two reactions achieve a 99.9% yield of stable hydrogen sulfide. JGC developed a second process for producing sodium sulfide, which uses hydrogen sulfide as a feedstock. The process technology has the advantages of being both safe and compact, and is already in use at five separate plants in Japan.

ZED is a subsidiary of Juhua Group, which we maintain good relationship through CDM business credits through the capture and storage of HFC23, a greenhouse gas. Under the comprehensive agreement, ZEDC will be able to sign the first contract licensing practical use of the process to a Chinese client.

This is the first time JGC has promoted its proprietary technology in another country via a domestic intermediary in that country.
