Production method of non-convertible combined methanol and dimethyl ether from coke oven gas

Abstract

The invention relates the producing method of coking gas non-convertible cogeneration methanol dimethyl ether, solving the problems of high dissipating energy, high cost and low conversion ratio. The method comprises the following steps: making coking gas decoking and desulfurizing, pressurizing them and putting them into converter, synthesizing methanol with copper as accelerating agent, transferring heat, cooling, separating, getting methanol, dimethyl ether and water, putting them into rectifying tower, getting methanol and dimethyl. The method is advanced and simple, and the product can replace diesel fuel, liquefied petroleum gas and Freon. The product is new pattern pollution-free energy and basis chemical engineering material.

Description

1. Technical Field

[0001] The invention relates to a production method for directly using waste coke oven gas produced from coking to produce methanol and dimethyl ether through non-conversion and co-production of methanol dimethyl ether, and is particularly suitable for coking enterprises. 2. Background technology

[0002] At present, the use of coke oven gas to produce methanol and dimethyl ether mostly adopts catalytic conversion and non-catalytic conversion methods, that is, coke oven gas is first converted, then methanol is synthesized, methanol is dehydrated to produce crude dimethyl ether, and the product is separated after rectification. However, this method has a particularly huge investment in production, it also needs to consume a lot of steam, high energy consumption, high cost, low ether conversion rate, and its products are difficult to effectively promote and apply. Third, the content of the invention

[0003] In view of the above situation, the purpose of the pre...
