On April 13^th, the Technology Selection and Profit Calculation System for Coal to Chemical Product Mixes jointly developed by Ningbo Technology Research Institute, Sinopec Economics and Development Research Institute and Sinopec Great Wall Energy and Chemical Co., Ltd. was assessed and accepted by the specialists organized by Sinopec Chemical Department.

Three representative coals, including brown coal, high quality bituminous coal and high ash content bituminous coal, were selected to determine the gasification technical routes for five product mixes, i.e., coal to natural gas, coal to methanol and then to olefin, coal to glycol, coal to vinyl acetate and coal to liquids (direct liquefaction) for the Technology Selection and Profit Calculation System for Coal to Chemical Product Mixes. Plant-wide system configuration was studied to determine the investment estimate and the tech-economic conditions for various product mixes. The crude average price in 2015, crude price in 70 US dollars per barrel and 90 US dollars per barrel were used to create the tech-economic estimation models, and the estimation outcomes were used to conduct tech-economic comparison and analysis and conclude recommendations for various price systems, various types of coals and various product mixes.
