Off-line chemical cleaning can basically remove the pollution.

This paper introduces some methods for guaranteeing the water quality of the primary cooling water system of the continuous casting machines of Taiyuan Iron & Steel complex such as depending on off-line cleaning, and slowing down the corrosion of the tanker of crystallizer, etc.

Based on the fouling analysis of atmospheric condenser and the application effect appraisal of on-line chemical cleaning, this paper points out that adopting on-line chemical cleaning can effectively prevent the overhead atmospheric condenser of vacuum distillation unit in PetroChina Karamay Petrochemical Company from fouling.
