Abstract:

A large state-owned refinery uses a combination of H/COMET crude oil data management software and APS refining scheduling optimization software, fully utilizing H/COMET's crude oil evaluation database and modeling and cutting functions, as well as APS's multi oil blending and multi cycle scheduling functions, to carry out crude oil optimization blending, and scheduling work. The application results show that the deviation between the yield of each narrow fraction calculated using this combination and the actual yield is within ±0.5%, and the crude oil blending plan can be accurately and intuitively formulated; by coordinating crude oil resources, the balanced optimization blending of crude oil is achieved, stabilizing the feedstock properties of distillation units; by rolling simulating the changes in crude oil variety, side line yield, and properties of the atmospheric and vacuum distillation feedstock within a certain period, a basis can be provided for the adjustment and arrangement of subsequent secondary processing units. This article also analyzes the problems that exist in the practical modeling application of the two software and provides solutions. The combination application of the two software can provide reliable support and assurance for refinery production optimization, operation management, decision analysis, and so on.
