Unloading process flow diagram
Liquid transport
Initially, the liquid phase pipe between the tank truck and the storage tank is opened. If the liquid level in the tank truck is higher than that in the storage tank, it will automatically flow into the storage tank and stop flowing when equilibrium is reached. If the liquid level in the tank truck is lower than that in the storage tank, the compressor is started directly, with the four-way valve in the positive position. Gas is drawn from the storage tank, pressurized, and then discharged into the tank truck through the compressor. At this time, the pressure in the tank truck increases, and the pressure in the storage tank decreases, causing the liquid in the tank truck to flow into the storage tank under the action of the pressure difference. (See diagram below)
