Yanchang Petroleum: Advanced Technology Fuels Green, Low-Carbon, High-Quality Development

Comprehensive Coal, Oil and Gas Project Advanced Technology Improves Resource Utilisation Rate

 

 

In Jingbian County, a total investment of nearly 40 billion yuan of comprehensive utilisation of coal, oil and gas resources project, so that Shaanxi Yanchang Coal Yulin Energy Chemical Co.

 

 

 

It is understood that the project's main devices include 2x1.8 million tonnes/year methanol, 2x600,000 tonnes/year methanol to olefin, 1.5 million tonnes/year residual oil catalytic thermal cracking and 6 sets of polyolefin devices with a total capacity of 1.9 million tonnes/year, using Yanchang Petroleum's ‘coal, oil and gas synthesis process comprehensive integration of proprietary technologies’, which has created a cleaner transformation of resources and diversified production of new fossil raw materials. The project adopts Yanchang Petroleum's proprietary technology of ‘comprehensive integration of kerosene and gas synthesis process’, creating a new path of clean resource conversion and diversified production of fossil raw materials, and putting into practice the new development concept of giving priority to ecology, being friendly to the environment, recycling, and saving resources.

 

 

Data show that the energy conversion efficiency of the project reaches 61.88%, and the utilisation rate of carbon resources reaches 55.75%. Compared with the modern coal chemical project, the energy conversion efficiency is increased by 16.88%, and the carbon resource utilisation rate is increased by 17.74%. The annual emission reduction is more than 6 million tonnes of carbon dioxide and 500 tonnes of sulphur dioxide. The wastewater reuse rate reaches more than 97%, saving more than 20 million cubic metres of water per year, and solving the bottleneck problem of highly concentrated brine treatment for energy and chemical enterprises.

 

Nowadays, Yanchang Petroleum is one of the top 500 enterprises in the world, and has built and put into production a number of industrial demonstration projects, such as comprehensive chemical park of coal, oil and gas resources, coal and oil co-refining, and syngas to ethanol. At the same time, it is carrying out a number of high-end energy and chemical technology pilot and demonstration, basically formed a comprehensive energy and chemical industry pattern, and has become an important force to protect the national energy supply and an important pillar of local economic development. As a local large-scale state-owned enterprise with oil and gas resources exploration qualification, Yanchang Petroleum leads the low-carbon, green and high-quality development of China's petroleum and chemical industry in the comprehensive utilisation of coal, oil and gas resources according to local conditions.
