Gas tightness test of distillation system
Thread Content
I would like to ask experts how to conduct a gas-tightness test on a distillation system (with detailed steps) Urgent!
The airtightness tests for distillation systems should be conducted separately depending on the system pressure. For methanol, it can be divided into three systems: a pre-tower, a pressurized tower, and an atmospheric pressure tower.
Pulse compressed air into the system, then seal it and test for leaks. Simply perform a hot wash and it will be solved.
It is best to conduct experiments using nitrogen, rather than a compressor
Cut off all connected pipelines, remove the blank flange from the nitrogen pipeline, and pressurize to 0.25 MP to identify any leaks.
Are there any relevant standards or specifications?
Conduct a pressure test by using ammonia to check for leaks at the ends of each flange
