Abstract

The invention discloses a preparation device and process of carbon monoxide. The device comprises a cracking zone and a purification zone which communicate; the cracking zone comprises a methanol storage tank, a methanol pump, a raw material preheater, a vaporizer, a heat exchanger, a superheater and a converter which communicate sequentially; the raw material preheater communicates with the heatexchanger and a recovered methanol heater respectively; the recovered methanol heater communicates with a gas-liquid separator, a condenser and the methanol storage tank respectively; the gas-liquid separator communicates with the condenser; the purification zone comprises a plurality of communicating adsorption towers; all the adsorption towers are connected with the gas-liquid separator, a replacement gas buffer tank and a compressor; the compressor communicates with the gas-liquid separator; the preparation process of the carbon monoxide comprises the following steps: (1)decomposing methanol; (2)separating and distilling a cracking gas, and recovering heat; (3) performing adsorption by the adsorption towers; (4) carrying out replacement washing; (5) sucking carbon monoxide. The device has no exhaust gas or waste liquid emissions in the preparation process of carbon monoxide, thereby being safe, environmentally friendly and low in consumption.

Description

technical field [0001] The invention belongs to the technical field of carbon monoxide preparation, and in particular relates to a device for preparing carbon monoxide and a process thereof. Background technique [0002] In order to meet the needs of the development of fine chemicals and provide high-quality carbon monoxide raw material gas for oxo-synthesis processes such as acetic acid and acetic anhydride, high-quality carbon monoxide is usually prepared by methanol cracking. A large amount of waste of carbon monoxide will produce waste liquid, which is harmful to the environment, and the heat of the pyrolysis gas cannot be effectively used, resulting in a large loss of heat and affecting the production efficiency. Contents of the invention [0003] Aiming at the above-mentioned shortcomings in the prior art, the present invention provides a device for preparing carbon monoxide and its process, which can effectively solve the problems of large environmental impact, low ...
