| Crude oil distillation device design and operation for oil refining enterprise plays a veryimportant role. It has a big effect to the product quality and yield the effective use of crude oil.In recent years, because of technical progress crude distillation device, the device can processflow, energy saving and automatic control. Considering the overall effectiveness of oil refinery,ensure the quality of products, construction period and so on, under the premise of accordingto the material properties and production plan, using load transfer technology, optimizing theoperation conditions. According to its different vaporization of section number process, findthe best operating parameters. Make the quality of the unit straight-run product energyconsumption is low, ensure that often of pressure-relief device secure, stable production.In this article, the process simulation software PRO/â…¡ for3million tons/year ofatmospheric distillation device are simulated, and crude distillation process of tower getoperation data, the device, mass balance data, two process each column of temperature,pressure and gas liquid load distribution, etc. And compared the two process flow of energyconsumption, through the PRO/â…¡ software to simulate a vaporization calculated the totalenergy consumption process for12.45kgEo/t; Two paragraphs of total energy consumptionvaporization process for10.39kgEo/t. So two segments of the flow of energy thanconventional vaporization a vaporization process saves16.5%. Therefore, in the actualproduction operation, we consider to choose two segments of the processing plan ofvaporization process. |
