Should a safety valve or pressure relief valve be installed in the condensate tank of the catalytic compressor area?
Thread Content
The catalytic compressor section collects the condensate from various parts into a condensate tank (not the intermediate condensate oil tank of the compressor), and then periodically pumps this oil to the crude gasoline gas-liquid separation tank. The compressed rich gas is pressurized to 1.2–1.3 MPa using the compressor outlet. The design pressure for the condensate tank is 1.2 MPa. Under normal conditions, a pressure of 0.7–0.8 MPa is sufficient to push the oil out, but sometimes the pressure relief valve is opened too widely, causing the pressure in the separation tank to reach 1.2 MPa. I would like to know whether it is necessary to install a safety valve in the tank or a pressure reducing valve at the pressure filling inlet.
The problem can be solved: 1. Install a safety valve on the top of the tank. 2. Connect dry gas with a pressure of 0.6~0.7 as the oil pressurization source.
1. The equipment must under no circumstances be operated at excessive pressure； 2. Careful operation can ensure control, as the actual operating pressure reaches 0. It can be pressed out at 7 o’clock; it is still a long way from the designed pressure, so there’s no need to install safety devices
The condensate at the inlet of our compressor is regularly pumped to the separation tank at the compressor outlet using a pump
