灵活应用LP模型提高炼油厂设计水平

炼油厂设计水平的高低首先取决于总加工流程的选择是否优化合理。本文利用PIMS软件提供的模块化和开放性结构的建模环境，结合炼油工艺特点，根据设计需要灵活地构建了各种LP模型，用于炼油厂实际总加工流程的优化设计中。同时重点介绍了其在原油配置、重油加工路线选择和新工艺评估方面的应用成果，结果表明其对提高炼油厂的整体设计水平具有重要指导意义。

Applying LP model to improve refinery design level

The process configuration is one of the key factors for a grass-root refinery with a high level in design. PIMS software with modular and open programming environment was used to develop some special LP models, which was closely integrated with the knowledge of all kinds of refining processes. These LP models were then applied in the design of a real refinery project to optimize the overall process configuration. The main conclusions were introduced including crude selection, process of heavy residue, evaluation of new technology. The results showed that LP model was an instructive tool to improve the refinery design level.
