Distance between liquefied hydrocarbon pump and storage tank

Thread Content

The plant has a horizontal ethylene semi-frozen storage tank with a capacity of 60 cubic meters. The process requires pressurizing the low-temperature liquid ethylene, at around 0.6 MPa, to about 6 MPa in order to vaporize it; the resulting high-pressure gaseous ethylene is then fed into the reaction vessel for use in the reactions. According to PTC Regulation 4.2.12, the distance between pumps and compressors in the plant’s tank area and the liquefied hydrocarbon tanks throughout the plant must be 25 meters. According to the liquefied hydrocarbon tanks in the facility, as per 5.3.4, the distance between the hydrocarbon pumps and the storage tanks must also be 15 meters. For cryogenic liquid pumps, if the pipeline ahead of the pump is too far from the discharge outlet – for example, 25 meters or 15 meters as specified – it will be extremely difficult to start the pump due to the high resistance ahead of it. Has any teacher encountered a similar situation? Are there any reasonable solutions? I have a question.
