Abstract

The embodiment of the invention provides an alkali liquor separation system and a cyclohexanone preparation system. The alkali liquor separation system comprises a first alkali liquor separator, a first mixer, a second alkali liquor separator, a second mixer and a third alkali liquor separator, wherein the first alkali liquor separator is used for carrying out oil-water separation on a to-be-separated liquid; a liquid inlet of the first mixer is separately connected with an oil phase outlet of the first alkali liquor separator, a water phase outlet of the second alkali liquor separator and a water phase outlet of the third alkali liquor separator; a liquid inlet of the second alkali liquor separator is connected with a liquid outlet of the first mixer; a liquid inlet of the second mixer isseparately connected with an oil phase outlet of the second alkali liquor separator, a water phase outlet of the third alkali liquor separator and an external water supply system; and a liquid inletof the third alkali liquor separator is connected with a liquid outlet of the second mixer. According to the alkali liquor separation system, washing water is recycled and diluted, so water consumption is reduced, and each alkali liquor separator is allowed to keep a relatively high alkali ion removal rate.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of preparation of cyclohexanone, in particular to an alkali liquid separation system and a preparation system of cyclohexanone. Background technique [0002] As an important chemical product, cyclohexanone is an important raw material for the production of adipic acid and caprolactam. At present, there are three main processes for producing cyclohexanone in the world: phenol method, cyclohexane oxidation method and cyclohexene method, among which more than 70% of the cyclohexanone manufacturers in the industry adopt the cyclohexane oxidation process. The process mainly includes oxidation, decomposition, separation of spent caustic soda, alkane rectification, saponification, refining, dehydrogenation and heat recovery. , will lead to fouling of the tubes of the reboiler, resulting in a decrease in the heat transfer efficiency of the reboiler, and insufficient power for the cyclohexa...
