The result shows that HF concentration is increased under the condition of low water content in acid, ASO content is effectively decreased without negative influence on alkylate quality and the acid consumption is reduced.

The demineralizing system in Guangzhou Yuancun Cogeneration Power Plant used to have problems of failed reclamation and high acid consumption.

Optimization methyl acetate recovery to reduce the acetic acid unit consumption in PTA plant;

The technique of decreasing the acetic acid unit consumption in PTA production;

Optimizing TA technology and decreasing acetic acid unit consumption;

In order to reduce acid and alkali consumption in the regeneration of ion exchange resin during water treatment, the best acid and alkali consumption is fixed through adjustment tests by countercurrent flow regeneration double-bed process in according to the requirements of water quality in the production, equipment of water treatment and process conditions.
