| Recet years,oweing to the air quality reduct in our country,various regions appear large-scale haze weather one after the other,which hits a history record on the influence extent and impact scope.The government accelerates the introduction of relevant policies on improving air qulity, paying particularly attention to State IV Standard.and State V Standard which will be improved in the future. State IV Standard.and State V Standard is strict requirements on sulfur content,one is no more than 50 mg/kg, the other is no more than 10 mg/kg 。As an important means on increasing octane number,the sulfur content in MTBE is payed more attention. There is consensus behind fiscal expansion on reducing the sulfur content in MTBE to suit State IV Standard.and State V Standard.The article is focused on the high sulfur content and the properties of sulfide in MTBE which is produced from 140000 tons / year MTBE unit in Daqing Refining & Chemical Company.Compare with which developed in our country,combine the focus such as Safe & Environment、product yield、running costs and so on,to choose suit desulfurization technology for the MTBE which is produced in Daqing Refining & Chemical Company.The article confirms the simple distillation desulfurization processcombine by comparing analysis among adsorptive distillation deep desulfurization process、adsorptive distillation alkali washing process and MTBE fine desulfurization CX, combining the focus on low sulfur content with the relative volatility in MTBE which is produced in Daqing Refining & Chemical Company which is suit for it. Compile practical desulfurization systerm commission plan, make sure that systerm start up successfully at one time. Combined with the design of the regulating operation parameters, under the premise of ensuring the desulfurization effecs to explore the optimal operating conditions,which makes the desulfurization systerm run steadily,energy consumption decrease, and the operation cost of the system be reduced. |
