Talking about the use of tank car with pump unloading process in LPG filling stations in order to reduce the pollution of vehicle exhaust to the atmospheric environment, purify and improve the gas environment for the city to provide customers with careful testing, and accelerate the development of green environmental protection, gas vehicles using clean energy began to be valued by people, and have been gradually applied and developed. Especially in the past ten years, the gas-fired vehicles in Beijing have developed rapidly, and the gas filling stations for vehicles have been built and put into use, but the resulting safety hazards have also attracted more and more attention. Due to the relative shortage of land, individual gas filling stations built in the urban area of Beijing are limited by the land conditions. The lead screw and lead nut are used as parts to implement the unloading pump of liquefied petroleum gas tanker (hereinafter referred to as tanker), and the liquefied petroleum gas storage tank (hereinafter referred to as storage tank) of the gas filling station is directly unloaded. In view of the universality of using this process at present, this paper analyzes the advantages and disadvantages of this process in order to better and more safely ensure the implementation of this process

advantages of using tank car unloading pump (2)

sense 1. Save land. Make the construction of oil and gas stations more feasible. When the compressor or ground hydrocarbon pump is set for the gas station to discharge the liquid from the storage tank, the compressor or ground hydrocarbon pump room shall maintain a certain fire separation distance from all buildings and structures in the gas station. Since the compressor or ground hydrocarbon pump needs to occupy a large land of the gas station, and the tank car unloading pump is used to unload the liquid from the storage tank of the gas station, the compressor or ground hydrocarbon pump may not be set in the gas station, which can make full use of the land of the gas station and provide the possibility for the construction of gas stations in some land-use difficult areas, especially providing favorable conditions for the transformation of existing gas stations into oil and gas mixing stations

2. Save investment. The tank car unloading pump is used to directly unload the liquid from the storage tank of the gas station. The gas station can no longer be equipped with a compressor or ground hydrocarbon pump. One tank car can be responsible for the gas supply of multiple gas stations, which can reduce the investment in equipment, housing construction and land of the gas station

3. Simplify the process flow. The tank car unloading pump is used to directly unload the liquid from the storage tank of the gas station, and the tank car unloading pump is regarded as a part of the process flow of the gas station. Compared with the gas station with compressor unloading, the process flow is very simple and easy to operate

4. Shorten the unloading time, and use the tank car unloading pump to directly unload the liquid from the storage tank of the gas station. The principle is to directly pressurize the liquid phase liquefied petroleum gas by using the pipeline pump, while the principle of compressor unloading is to change the pressure difference between the tank car storage tank and the storage tank of the gas station by using the compressor. At the same time and the same energy consumption, the unloading pump is much larger than the compressor unloading. 7) the appearance of the packing powder of the product is uniform, and the particle size is much larger
