Optimal Design Of Liquid Hydrocarbon Dual Desulfurization Device In Liaohe Petrochemical Company

Liaohe Petrochemical Company liquid hydrocarbon dual off device for the whole plant liquid hydrocarbon desulfurization, and the production of liquid hydrocarbon is the main raw material for production of methyl tert butyl ether(MTBE), MTBE is gasoline blending into one of important additives.With the country in recent years to improve the quality standard of MTBE gasoline, the quality requirements must constantly improve. But because the desulfurization equipment technology obsolete, resulting in MTBE total sulfur content high, gasoline blending difficult. In order to reduce the sulfur content of MTBE in the liquid hydrocarbon double off device can only take the frequent replacement of liquid alkali to adjust the quality of the products, such as on the one hand, the formation of a large number of soda residue, increased processing costs, on the other hand, frequent change of base pose a security risk. The introduction of liquid hydrocarbon desulfurization in the coking and double liquid hydrocarbons with higher sulfur content, the device production more difficult. To solve a series of problems, through the analysis of the production technology of sweetening liquid hydrocarbon desulfurization, find out the Petrochemical Industries Co unit capacity, operation and control measures are not perfect, old measures not perfect, no bottleneck extraction method. To counter the problem of running grams of clothing At the same time, with the purpose of reducing the cost and improving the efficiency, the principle of safety and environmental protection, the introduction of the market the new catalyst, solvent and the latest technology of fiber film desulfurization technology and formed a set of reasonable optimization design. Continuous improvement on the quality of liquid hydrocarbon desulfurization from to cope with the market requirements, in order to achieve MTBE to reduce sulfur content, upgrading the quality of gasoline, energy consumption, agent consumption is reduced, caustic sludge emission reduction, reduced the efficiency and other issues.In this paper the liquid hydrocarbons removal of mercaptan system in catalyst alkaline solution regeneration process of traditional heating process at room temperature and the contrast and research the different catalysts or additives where implications of lye regeneration effect, the optimization design of selected normal regeneration process and conventional sweetening combined removal of mercaptan and fiber membrane method for desulfurization and its application in the specific process of chemical production, and draw the final conclusion to help and guide the adjustment of actual chemical production process and process parameters, and to new technology, new agents in the field of chemical application with have certain theory value and practical significance.
