MTBE production
Thread Content
In the production of MTBE, during distillation, MTBE is obtained from the bottom of the tower. It is said that most of the sulfides present in those four types of mixed hydrocarbons are concentrated in MTBE – is that true? Are there any ways to reduce the sulfur content in MTBE? Thank you!
Search online: There are many resources available on MTBE sulfur reduction solutions.
Just add a desulfurization device to the raw materials
Adding two desulfurization towers will solve the problem easily
Our company’s refining-type MTBE is equipped with an additional desulfurization tower, which allows the sulfur content in MTBE to be kept below 15
The MTBE product goes to the top of the tower, while the high-sulfur components go to the hydrogenation unit at the bottom of the tower.
Depending on the crude MTBE composition, add one column or two columns.
There are two approaches for MTBE desulfurization: one is pre-desulfurization, that is, desulfurizing the raw material, but this is time-consuming and labor-intensive, requires significant investment and high energy consumption; it is not recommended unless pre-desulfurization is necessary under specific operating conditions. Second is post-desulfurization, that is, desulfurization of the product; it requires relatively low investment, has a simple process, and most importantly, it offers excellent versatility. It is recommended to use this process.
Well, the new units these days mostly use post-tower desulfurization; it’s a simple process with low energy consumption
