Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of methyl tert-butyl ether, in particular to a recovery device for methyl tert-butyl ether. BACKGROUND

[0002] Methyl tert-butyl ether (MTBE) is a colorless transparent liquid, has ether special smell, boiling point 55.2℃, slightly soluble in water, easily soluble in organic solvents, as a high octane gasoline additive, can improve the anti-knock, reduce exhaust pollution, has been widely used.

[0003] In the process of producing and manufacturing methyl tert-butyl ether, the methanol in the mixture of methanol and C4 needs to be recovered.

[0004] The prior art often uses water washing tower equipment to recover methanol. Methanol is a polar molecule and can be miscible with water (polar solvent) in any proportion. After the gaseous mixture containing methanol (such as reaction tail gas, volatile gas) enters the water washing tower, it is in countercurrent contact with the water from top to bottom. The methanol molecules quickly dissolve in the water due to the "like dissolves like" principle, forming a methanol aqueous solution, thereby separating from other gases (such as C4, hydrocarbons, etc.) that are not soluble in water. However, the existing water washing tower equipment generally uses a spray head to spray liquid downward and a gas flowing upward in a gas-liquid countercurrent contact mode. However, during actual operation, due to factors such as gas inlet structure design and uneven distribution of fluid resistance in the tower, the lateral distribution of gas in the tower is difficult to achieve an ideal uniform state, and local flow rate is prone to be too high or too low. In the area with high flow rate, the gas-liquid contact time is insufficient, and the methanol cannot be fully dissolved. In the area with low flow rate, there is liquid bias, which leads to a decrease in mass transfer efficiency and causes poor methanol recovery effect.

[0005] Therefore, we propose a recovery device for methyl tert-butyl ether. SUMMARY
