SEG® Technology

Since 1980s, UBE Machinery Co., Ltd. is committed to the technological research on dimethyl oxalate and dimethyl carbonate production through coal-based syngas. UBE factory has the world's only 10,000 ton class DMC/DMO production system (raw materials synthetic gas) and it has been running stably for more than twenty years.

Under the technical support from UBE, HighChem Group jointly conducted ethylene glycol production technology with dimethyl oxalates hydrogenation with East China Engineering Science and Technology Co., Ltd.(ECEC), Zhejiang Realsun Chemical Industry Co., Ltd. The company also built the pilotscale experiment base, improved the technology package of the ethylene glycol production through synthesis gas, and promoted the technology in China. The world’s first CTEG production system was successfully put into production in Xinjiang in early January 2013.
