地方炼厂加工原料的优化

Optimizing the feedstock mix for teapot refineries

在地方炼厂原料构成中,原油偏少,加工原料呈重质化和多元化,主要包括原油、燃料油、沥青、蜡油等。地方炼厂的原料成本占炼制成本高达90%以上,不同原料的价差影响着原料成本。本文建立地方炼厂效益测算模型,针对不同的原油、燃料油价格差条件,测算并分析不同原料结构和加工路线的加工效益,以及原料和产品进、销项消费税抵扣平衡对炼油效益的影响。原料结构与加工路线优化对地方炼厂的生存与发展具有重要的意义。

Teapot refineries' feed stock mix contains a relatively small amount of crude oil but many heavy and diversified raw materials, including crude oil, fuel oil, asphalt, wax, etc. The cost of raw materials accounts for up to 90% of a local refinery's refining cost. A profit calculation model is presented for local refineries, and can measure and analyze the processing efficiency of different feed stock mixes and processing routes as well as analyze the influence on the monetary balance between feed stock purchase and product sale depending on differences between different crude oil and fuel oil prices. Optimizing feed stock and processing route is of great importance to the survival and development of local refineries.
