How MTBE reduces sulfur content
Thread Content
What is the sulfur content level that everyone aims for in MTBE, and how is it controlled? Our company has implemented advanced desulfurization processes to separate the high-sulfur components from MTBE, thereby reducing its sulfur content
I’m not sure what device your raw materials come from. If they originate from a dehydrogenation process, the excessive sulfur content in MTBE may be caused by sulfur leakage from the dehydrogenation unit; in that case, it is possible to adjust the amount of sulfur injected into that unit.
C4 from the gas fractionation unit; the total sulfur content in C4 is around 30
It is divided into pre-desulfurization and post-desulfurization. Pre-desulfurization involves reducing the sulfur content in the liquefied gas to around 1.0 ppm, to ensure that the sulfur content in MTBE remains below 10 ppm. Post-desulfurization is MTBE distillation, which separates the high-sulfur components. The former is more difficult but yields a higher MTBE yield, while the latter results in significant MTBE loss.
Deep desulfurization of MTBE results in the formation of some high-sulfur compounds, and some MTBE is lost; however, this process makes it easier to control the sulfur content. It is difficult to keep the sulfur content in the pre-desulfurized liquefied gas at 1 ppm
Is there a pentane removal tower in the gas section? Try to separate out the heavy components first, and then use the double-desulfurization method for liquefied gas desulfurization; this way, the yield of MTBE product is relatively high
Tell me how your double-tower method removes sulfur What’s the specific process?
Where have gone the high-sulfur compounds that separated from you?
After being separated in a distillation tower, MTBE still requires further deep desulfurization, with the sulfur content generally reduced to below 10 ppm, practically none at all. High-sulfur dirt removal oil tank at the bottom of the desulfurization tower
