Technology Licensing JGC Plans to Market Proprietary Sulfide Processes in China
JGC will provide its proprietary hydrogen sulfide and sodium sulfide production process technology for customers in China: The Japanese company has signed a license agreement with with Zhejiang Engineering Design, to serve as a proxy for licensing the technology to Chinese clients.
Yokohama/Japan – Hydrogen sulfide is used for the production of sulfur-containing compounds. The demand for this raw material has increased significantly in recent years, as it is used 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 300 billion yen 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. The agreement marks the first time that JGC has promoted its proprietary technology in another country via a domestic intermediary.
