Abstract
The explanation of outline to distillation method of the crude oil and craft characteristic of the atmospheric pressure tower was done in this paper. It introduces the basic principle of the distillation technology with a series of characteristics. It also describles the range of industrial application of distillation technology and developing prospect domestically as well as internationally and the future research trend are pointed out. On the basis of extimation of physical properties data and tray temperature self-tuning technology, a rigorous model is presented, the paper is designed for processing light Da Qing crude oil. It has greater flexibilities both in operation and product slates, and have greater feasibility in industrial production.
The first part in the design is the calculation of craft parameter about the atmospheric pressure tower by every known condition. The second part is the structure calculation, which calculate the physical dimension and type of every part of atmospheric pressure tower according to the craft parameters calculated in the front. The third part is the examination for the internsity. It is the key that proves whether the atmospheric pressure towers designed accord with the standard and could be put into production. The following conclusiont was known by research: the targets, which every performance index accords with the standard and the structure is arranged rationally, can increase capacity, save energy, rase product quality and recovery rate, stabilize production process etc.
Key words:distillation tower;atmospheric pressure tower;atmospheric distillation device
