Model and simulation of a hydrotreatment reactor for diesel hydrodesulfurization in oil refining

摘要

One of the most developed industries in the world is the industry dedicated to extraction and treatment of crude oil, due to his economic profitability. One of the equipment more important in any process is the reactor, which is the place where the physico-chemical transformations of the matter are carried out. The hydrotreatment process is used in oil refining, to decrease the level of different contaminants in the crude. Usually, this process is applied to the clearance of sulphur in contaminated streams. The process was modeled and simulated through the Open Source DWSIM software, using hydrogen as reactant and Ni-Mo ......2..3 as catalyst. As product was obtained acid crude. It was chosen the model Chao Seader to predict the main properties of each compound present in the reactor. Through the reuse of hydrogen in the system, it was possible reach a 0.0093% weight of Sulphur in the final crude stream. Furthermore, it was designed the furnace used to warm up the mixture for the reactor and the cooler used to separate the volatile compounds.
