High pressure drop in the oil and gas line at the top outlet of the fractionation tower
Thread Content
The pressure drop in the section from the top outlet of the fractionation tower to the oil-gas separator is high. What could be the reason, according to everyone here? (Process: Vapor and oil at the top of the tower —— heat exchanger between vapor/oil and hot coal water —— cooling of vapor, oil, and water —— vapor and oil separator; the vapor and oil butterfly valve is located at the outlet of the vapor and oil separator)
I’m not curious about anything else; I’d like to ask why oil and gas butterfly valves are installed at the outlet of the oil and gas separator Which design institute designed it?
Does the occurrence of a phase change when oil and gas are cooled cause a sharp decrease in volume?
1. Butterfly valve failure to close; 2. Fouling of the foam filter in the oil-gas separator; 3. Flow deviation or liquid seal issue in the heat exchanger; 4. Salt buildup in the pipelines. Identify the cause and then take appropriate action.
I’m curious about the pressure drop issue; as for your curiosity regarding the design location of the oil and gas butterfly valve, well, there’s no conclusion on that yet
