LPG desulfurization issue
Thread Content
Using coking gas (50% hydrogen sulfide, 1500 ppm total sulfur) as the main raw material for the gas separation unit and MTBE, how can desulfurization be carried out so that the sulfur content in MTBE and the butane liquefied product obtained after etherification remains low?
Desulfurization of coking gas is a challenging task. Using the amine method, hydrogen sulfide can be easily removed to levels below 1 ppm. However, after alkaline washing, the total sulfur content remains high. The total sulfur content in tetrahydrocarbons after etherification is definitely within acceptable limits and does not remain high. It is difficult to control the sulfur content in MTBE; it is necessary to use a light tetrahydrocarbon tower or a pentane removal tower to remove sulfur while also eliminating heavy tetrahydrocarbons and pentanes.
Using a combination of amine-based desulfurization and fiber membrane alkaline desulfurization will work
One could pay attention to the sulfur-reduction technology used by Zhanjiang Petrochemical for MTBE; currently, the sulfur content in MTBE is between 20 and 30, and the technology in question comes from Hebei Jingzhi Technology Co., Ltd.
Our company employs a series of desulfurization technologies to reduce the total sulfur content in MTBE. These include amine-based desulfurization, advanced desulfurization of liquefied gas, and MTBE distillation techniques, which enable the sulfur content in MTBE to be kept below 10PPM.
