Treatment of residual water remaining in the system after water transportation at the initial start-up
Thread Content
I would like to ask the experts: when the system is first put into operation and water is circulated through it, how is the remaining water dealt with? Should nitrogen be used for drying, or should it be fed directly into methanol so that the water dissolves in the methanol and is then separated using a methanol-water tower? Thank you.
Blow off first; only proceed with methanol after the dew point meets the requirements!
It should be purged first, before introducing the medium
Industrial air is used for purging and leak testing, followed by nitrogen replacement and leak testing
I have another question: Is it easy to purge the water remaining in each heat exchanger? Can it be cleaned thoroughly?
1. During the construction phase of equipment and pipeline projects, process engineers should ensure quality control; at the same time, low-point drain guides should be installed in pipes where liquid may accumulate, for both the drainage after water testing, as well as the drainage resulting from process treatment and alcohol removal during equipment and pipeline maintenance.
