What are the principles for dealing with leaks in static equipment?
Thread Content
What are the handling principles for leaks in the static equipment used in coal-based ethylene glycol production? I hope the experts here can offer some guidance
Whether the leak poses a threat to safe production, how to prevent the leak from expanding, and whether it is possible to seal the leak while the system is under pressure.
A leak in a pressure vessel certainly affects its safe use; it is necessary to determine the cause – whether it is a leak at the simple flange connections or at the welds of the vessel’s main structure or its connecting pipes – and emergency measures should be established.
It’s not detailed enough; please clarify what has leaked and what the operating conditions are
The original poster should provide more details: the parameters of the equipment, the operating conditions, and the location of the leak. Different types of leaks require different handling methods
To prevent the expansion of leaks, production can be reduced in volume and pressure. If the leakage is severe, an emergency shutdown can be initiated.
For minor non-process gas leaks, it is possible to seal them while the system is under pressure.
Eliminate potential hazards to ensure the safe operation of the equipment. If it can be repaired, then repair it; if not, it has to be replaced.
Thank you for your positive responses. The pressure in my system is 0.423 MPa, and there is a gas circulation compressor that keeps the gas circulating. The gas phase contains CO, O2, N2, and DMC (dimethyl carbonate), while the liquid phase consists of methanol and nitric acid as feedstocks. Now I need to prepare a plan for dealing with leaks in the static equipment, but I’m not sure how to do it since I’m a beginner without any operational experience. Therefore, I hope everyone can offer me some advice.
Pressurized sealing technology can be employed.
