I would like to ask the experienced colleagues about the issue of cleaning lines at the start of operations
Thread Content
Dear seniors, I would like to learn about the precautions to be taken when purging an ethylene plant. Additionally, I’m interested in knowing what considerations should be taken when purging the pipelines used in cryogenic separation. I appreciate your guidance; thank you. It would be even better if you could provide information on the purging procedures for units related to pre-propane removal and pre-hydrogenation.
What is scanning? Checking the line?
Line cleaning refers to the process of purging pipelines, thereby blowing out slag and other debris from within them
Work can be carried out step by step as required.
When starting up the line cleaning process, it is important to control the gas flow rate and ensure that the pressure does not exceed the operating pressure; in addition, the instruments, including the flow meter, must be removed. This post was last edited by limingshuguang on 2007-12-27 08:48.]
Attention should also be paid to the purging medium during purging. Safety issues must be taken into account! :lol
