Calculation of cooling shrinkage piping for large air separation unit

Calculation of cooling shrinkage piping for large air separation unit
Designers need to calculate and analyse and then judge that the whole process of realisation is that firstly the temperature of the gas source drops more slowly when the expander is switched on, so that when the expanded air silence enters the upper tower, it then passes through the upper tower through the dirty nitrogen pipeline, the nitrogen pipeline and the oxygen pipeline to the plate fin heat exchanger.

The pre-film of circulating water system is to improve the film-forming effect of corrosion inhibitor. We often add a higher concentration of corrosion inhibitor at the beginning of the circulating water drive, and after it has formed a film, then reduce the concentration of the agent to maintain the replenishment film. This pre-film treatment is to quickly form a protective film on the metal surface, to improve the corrosion inhibitor inhibit the effect of corrosion.Practice has proved that in ...
