Techno-economic analysis of the coal-to-olefins process in comparison with the oil-to-olefins process

Techno-economic analysis of the coal-to-olefins process in comparison with the oil-to-olefins process. Xiang, D., Qian, Y., Man, Y., & Yang, S. Applied Energy, 113:639–647, January, 2014.

Paper doi abstract bibtex

Oleﬁns are one of the most important oil derivatives widely used in industry. To reduce the dependence of oleﬁns industry on oil, China is increasing the production of oleﬁns from alternative energy resources, especially from coal. This study is concerned with the opportunities and obstacles of coal-to-oleﬁns development, and focuses on making an overall techno-economic analysis of a coal-to-oleﬁns plant with the capacity of 0.7 Mt/a oleﬁns. Comparison is made with a 1.5 Mt/a oil-to-oleﬁns plant based on three criteria including energy efﬁciency, capital investment, and product cost. It was found that the coal-based oleﬁns process show prominent advantage in product cost because of the low price of its feedstock. However, it suffers from the limitations of higher capital investment, lower energy efﬁciency, and higher emissions. The effects of production scale, raw material price, and carbon tax were varied for the two production routes, and thus the operational regions were found for the coal-to-oleﬁns process to be competitive.
