Abstract:

An alternative crude oil selection method which combines with the refinery mathematical programming modeling method and the selection of recipe of crude oil method is developed. This method is used to solve the problem of a large fuel-lube based refinery of which supply of Daqing tube-mixed oil is about to stop. Two kinds of planning cases have been calculated in mathematical programming model to determine which recipe of import crude oil is the appropriate one to replacing the existing Daqing tube-mixed oil. One kind of planning cases is calculated under the condition of lubricant base oil production, the other is calculated under the condition of no lubricant base oil production. The article results show that the recipe of import crude oil which selected by the method described in this article is not only suitable for the refinery process characteristic and the constraints of crude oil transmission, the supply of crude oil resources is also guaranteed, and the price and implementation of the oil also has advantages. The appropriate alternative crude oil can significantly improve the economic benifits of the refinery for 25-137 yuan per ton.
