Feasibility Research Of 600 Kton/Year Coal To Olefins Project Of Kailuan Group

Kailuan Group had controlled coal resource of a total of 5.3 billion tons in east Junggar basin of Xinjiang province now. Because the local coal consumption was not big and transportation difficulties, The coal is translated into high added value petroleum chemical substitute products in situ which could not only ease tensions of petroleum resources in China to a certain degree but also bring considerable economic benefits for the enterprise, moreover it could boost the development of local economy and employment and improve social benefits.Based on the systematic literature research, this thesis analysis and evaluation the quality of coal of Kailuan in east Junggar basin of Xinjiang province, then using the method of comparative analysis to determine the corresponding gasifier type and supporting the gasification process. After a comprehensive technical comparison, the thesis select and determine the corresponding core technology of methanol to olefins and the matching process including synthesis gas purification process, methanol synthesis process, methanol distillation process, olefin separation process, polyethylene and polypropylene process, and utilities, and carry out the study on the influence of safety and environmental according to the selected technology route. On the basis of the above, the thesis carry out the technical and economic evaluation of coal to olefins project.The research results show that this thesis proposed the construction of 600 kton/year coal to olefins project is feasible in technology and economy, and the project has strong profitability and anti risk ability and market competitiveness.
