Abstract Distillation, the major process in crude oil refineries as of now. In this work we focused the attention to energy saving with respect to an industrial crude oil distillation unit. An alternative to the conventional crude oil distillation model present in the Bharat Petroleum Corporation, Kochi Refinery is proposed and simulated. The theoretical predictions as well as the simulated results indicate that the Progressive crude oil distillation reduces the utility burden as well as increase the extraction of more valuable light components. The simulation was carried out using Aspen HYSYS V8.8.2. Different crudes are taken into account and their properties and amount of distillate are analyzed. The optimization is done in an easy manner rather than the conventional mathematical method, together with the advanced process control tools; make it profitable in the operation in real time.

渐进式原油蒸馏：传统蒸馏工艺的节能替代方案

摘要 蒸馏是目前原油精炼厂的主要工艺。在这项工作中，我们将注意力集中在工业原油蒸馏装置的节能上。提出并模拟了高知炼油厂 Bharat 石油公司现有的传统原油蒸馏模型的替代方案。理论预测和模拟结果表明，渐进式原油蒸馏减少了公用事业负担并增加了更有价值的轻组分的提取。使用 Aspen HYSYS V8.8.2 进行模拟。考虑了不同的原油，并分析了它们的性质和馏出物的量。优化以简单的方式完成，而不是传统的数学方法，再加上先进的过程控制工具；
