Dongxinyuan's clean coal technology is leading in China

　　On June 28, the new clean coal products developed by Shaanxi Dongxinyuan Chemical Co.
, Ltd.
passed the key new product appraisal in Shaanxi Province organized by the Shaanxi Petroleum and Chemical Industry Federation in Xi'an
.
The appraisal committee headed by Professor Li Wenhong of the School of Chemical Engineering of Northwestern University unanimously agreed that the production technology of this new product has reached the domestic leading level
.

　　Experts believe that Dongxinyuan Company has optimized the integrated application of a series of innovative technologies, improved the quality of clean coal products, achieved safe, continuous and stable production, and has obvious energy-saving and environmental protection effects in the production process.
It is recommended to further increase the promotion of related product production technologies
.

　　Li Yajun, deputy general manager of Dongxinyuan Company, introduced that in response to the technical problems of the industry, the company has successfully developed a new type of coal upgrading furnace-type fire channel wall special-shaped structure (eaves effect) and process, furnace roof sealing gas anaerobic through independent technical research in recent years.
A series of technologies, such as desorption gas to replace return gas, phenol and ammonia wastewater, water, oil, ammonia and sulfur separation treatment, etc.
, have been applied to industrial production practice, realizing comprehensive pyrolysis and quality improvement of pulverized coal, seed coal and lump coal, and expanding the selection of raw materials.
The production cost is reduced, the energy consumption level is reduced, and the quality of clean coal products is also improved accordingly
.

　　According to the analysis and testing of the National Coal and Salt Chemical Products Quality Supervision and Inspection Center (Yulin), the fixed carbon content of clean coal products is higher than 86%, the moisture content is lower than 10%, the volatile matter and ash content are lower than 7%, and the sulfur content is lower than 0.
25%.
, technical performance indicators are better than the national and local standards
.

　　Since the clean coal production plant was transferred to the trial production stage in January 2021, Dongxinyuan Company has achieved a significant improvement in the quality of clean coal products produced through the integrated application of a series of innovative technologies, and the plant has been operating continuously, safely and stably
.
Through the independent declaration of Dongxinyuan Company, in May 2022, the new clean coal products were included in the 2022 key new product development project plan in Shaanxi Province
.
As of mid-June 2022, the company has produced more than 900,000 tons of clean coal this year
