Abstract

The invention relates to a method for desulphurizing MTBE with high sulphur content, belonging to the field of the refining of methyl tertiary butyl ether (MTBE). The methyl tertiary butyl ether (MTBE) with high sulphur content is placed into a distillation tower and heated by a reboiler, the temperature of a tower kettle is kept between 90 DEG C and 120 DEG C, the pressure of the tower kettle iskept at 0.08+ / -0.02 MPa, the temperature of a tower top is kept between 69 DEG C and 75 DEG C, and the pressure of the tower top is kept at 0.06+ / -0.02 MPa so that a finished product is distilled outof the tower top, a reflux ratio is kept from 1 to 10, and a sulfur product is recycled from a tower bottom. The invention has the advantages of simple process, advanced technology, easy and convenient control operation, little investment, low cost and no three-waste pollution.

Description

(1) Technical field

[0001] The invention relates to the refining of methyl tertiary butyl ether (MTBE), in particular to a method for desulfurization of high-sulfur MTBE. (2) Background technology

[0002] In recent years, with the adjustment of energy structure, my country's fine chemical industry has developed by leaps and bounds, and large-scale desulfurization units have been built one after another. Because of the high boiling point of sulfur in MTBE products, it is not easy to volatilize, has high toxicity, and corrodes equipment seriously, making it difficult to recover. The exhaust gas is discharged, causing serious environmental pollution and energy waste.

[0003] At the same time, under the influence of high global oil prices, the price of major basic organic chemical products has been rising, especially the price of gasoline remains high. Due to the high octane number and low vapor pressure of MTBE products, it can increase the price of gasoline. It has been widel...
