Abstract

A method lengthening the cyclohexanone device continuous running period and equipment are provided. The method can completely and effectively separate the oxidation solution waste alkali of the cyclohexanone and realize the low energy consumption, small investment and pollution, which is suitable for the stable running for long period.

Description

Technical field [0001] The invention relates to a method for extending the continuous operation period of a cyclohexanone device. More specifically, it relates to a dealkalization method for the waste alkali produced in the production process of cyclohexanone by first injecting water to enrich the alkaline substance, and then performing cyclonic separation of the alkaline water from the organic acid and ester. The invention also relates to equipment for extending the continuous operation period of the cyclohexanone device. Background technique [0002] As an important organic chemical product, cyclohexanone has a wide range of uses. Our country also imports 30-50% of domestic output of cyclohexanone every year. In the production process of cyclohexanone, the oxidation liquid produced by the oxidation process is treated with a strong alkali (3-5% sodium hydroxide) aqueous solution in the decomposition kettle to produce water, sodium hydroxide, organic sodium salt, Saponified was...
