30万吨年催化重整车间脱水工段的初步设计 摘 要 本设计是30万吨/年催化重整车间脱水工段的初步设计。催化重整是石油加工和石油化工的重要工艺之一，催化重整技术是以石脑油为原料，在催化剂的作用下，烃类分子重新排列成新分子结构的工艺过程。其主要目的：一是生产高辛烷值汽油组分；二是为化纤、橡胶、塑料和精细化工提供原料（苯、甲苯、二甲苯，简称BTX等芳烃）。它在石油炼制工业中占有举足轻重的地位。而预处理中的脱水工段是催化重整车间里重要工段之一。其作用是对重整原料进行预处理，以使原料满足重整反应的要求。脱水工段的设计质量和运行好坏将会直接影响的重整反应的进行。通过对大庆石化炼油厂的实地考察以及通过在图书馆查阅大量的相关技术文献，对脱水工段的脱水塔进行了初步设计，包括塔的各种计算，比如物料衡算，热量衡算,塔的设备选型计算，带控制点的工艺流程、主要设备装配图及车间平面布置的CAD图，Aspen_Plus催化重整脱水工段全流程动态模拟。 关键词: 催化重整；预处理；石脑油；脱水塔；设计 Abstract The design is the preliminary of 300,000 tons/year catalytic reforming plant dehydration Section. Catalytic reforming of petroleum processing and petrochemical process. The role of Catalyst. Hydrocarbon molecules re-arranged in the process of the new molecular structure.Its Main purpose: Firstly, theproduction of high octange gasoline components; The second is to provide raw materials for chemical fiber, rubber, plastics and fine chemicals (Benzene, toluene, xylene, referred to as BTX and other aromatics). So it is a pivotal position in the oil refining industry. Pretreatment of dehydration section become one of the catalytic reforming sections. In order to hit the requirements of reforming reaction, it plays important role in dealing with the raw materials. The quality of the catalytic reforming is affected by the design quality and the operation of the dehydration section. Through field visitsof the Daqing Petrochenical refineries as through access toa large number of related technical literature in the library. Dehydration tower dehydration.
