Pressure rating of pure benzene vapor recovery line
Thread Content
Dear colleagues: For the closed-loading of pure benzene onto ships, the GC1 pipeline is used for the product stream. But what grade is required for the product vapor return line (the mixture of gas from the empty ship hold and benzene vapor), and what is the basis for this? What is the basis? (The pressure in the steam return line will not exceed the pressure setting of the cabin pressure relief valve.) Could someone please let me know? I’m waiting here! ! ! :hug:
If the pressure does not exceed 0.1 MPa, it is not considered a pressure pipeline, according to the definition of pressure pipelines in the Regulations on the Supervision of Pressure Pipelines.
