The reporter was informed by the Erdos City Government in Inner Mongolia that a major milestone has been achieved with the successful trial operation of a 20,000 tons per year dimethyl ether (DME) production plant located in the Wushenzhao Industrial Park in Ordos City. This facility, operated by Inner Mongolia Yigao Chemical Co., Ltd., marks the first operational DME production line in the region and represents a significant technological breakthrough for the local chemical industry.
According to the report, the production technology used in the plant is an independently developed system that integrates and optimizes both domestic and international DME production methods. Following more than ten days of stable trial operations, the plant successfully produced high-quality DME with low energy consumption and consistent performance, demonstrating its commercial viability.
It is worth noting that the company, known as Yihua Group, has been actively involved in the development of methanol-based downstream products since 2004. In that year, the group, along with Japanese company Gaohua Co., Ltd., invested over 25 million yuan to explore new applications for methanol. By August 2004, they had initiated pilot testing for DME production, laying the groundwork for future expansion.
Currently, the 20,000-ton annual capacity DME plant is the first in Inner Mongolia to have independently developed DME technology. The successful operation of this facility not only supports the larger 3 million tons per year coal-based DME project being planned by Yihua Group at the Mengda New Energy Development Base in Wushenqi but also provides critical technical support for the 30,000-ton DME production unit at the Alkali Lake test station. This development signals strong growth potential for the company and reinforces its position as a leader in clean energy production in the region.
