Coal-based synthesis gas production polymerization grade ethylene glycol pilot test

Key technical indicators rank the leading international level

On December 12, the National Energy Administration organized relevant experts to convene an appraisal meeting for the production of a polymerization grade ethylene glycol pilot project with an annual output of 300 tons of coal-based syngas in Beijing. Experts believe that the research and development of this achievement has been successful and has achieved new breakthroughs in the traditional coal chemical industry, which can improve the overall level of China's coal chemical industry.

According to reports, the results are based on the energy structure characteristics of China's “oil shortage, low gas, and rich coal” and adopt a new set of new technology for the production of polymerization grade ethylene glycol from coal-based syngas with complete independent intellectual property rights, including the five China Patented and reactor know-how, esterification regeneration technology, rectification and refining technology, and proprietary analysis and testing, and four proprietary technologies, after an annual output of 300 tons of coal to syngas production of polymerization grade ethylene glycol pilot plant The stable operation inspections, and the major technical indicators have made further breakthroughs on the existing domestic basis. Among them, the key technical indicators such as the selectivity of CO selective dehydrogenation catalysts, the space-time yield of dimethyl oxalate synthesis catalysts, and the selectivity of ethylene glycol hydrogenation catalysts for oxalic acid are among the leading international standards.

Experts believe that the use of the new technology to produce ethylene glycol, product quality by the National Petroleum and Petrochemical Products Quality Supervision and Inspection Center (Guangdong) testing, while achieving the GB/T4649-2008 superior products and the United States ASTME2470-2007 polymerization level standards; using the new The development of technological achievements The production of ethylene glycol as a raw material for the production of ethylene glycol complete sets of process technology can complement and replace some of the purpose of oil consumption. It is important to ease the oil shortage in China, reduce the dependence of the polyester industry on imported ethylene glycol, and ensure energy security. significance.

The project was jointly developed by China Wuhuan Engineering Co., Ltd., Huashuo Technology Co., Ltd. and Hebi BMW (Group) Industrial Co., Ltd.

Underground Oil Distillation Plant

1. Introduction of underground oil distillation plant

Underground Oil Distillation Plant ,is the new technology which can refine the underground oil into base oil(which can be made into diesel and gasoline after processed by our catalyst) by vacuum pressure distillation system. The oil quality is better than the original normal pressure distillation technology, which show on purity ,transparence, lightness .this technology will do deodorization and destinke process to the raw material oil automatically by "dry type" vacuum pressure distillation method. With the vacuum distillation technology, the distillation temperature is considerably reduced, and the oil output will higher 5%-10% compared with original normal pressure distillation technology. It makes more profits to the enterprise virtually.

2. Raw material which can be used

a. Waste oil .example: waste diesel, waste oil residue etc.

b. tire/rubber oil

c. plastic oil

d. crude oil

e. waste engine oil

f. waste motor oil

g. waste lube oil

h. waste transformer oil

i. underground oil

3. Models of underground oil distillation plant

4. Installation: We will be in charge of arranging our engineer to go to your place to guide the installation and train your workers how to operate the underground oil distillation plant ,and buyer will be in charge of the food, accommodation and round air tickets.
