Oil Free Unloading Ammonia LPG Bog Compressor Use in Filling Station

Product Description

The oil-free unloading ammonia LPG bog compressor is a high-quality and reliable compressor manufactured by our company, designed specifically for use in filling stations. This compressor is essential for the unloading, loading, dumping, residual gas recovery, and residual liquid recovery of LPG/C4, propylene, and liquid ammonia. It is widely used in the gas, chemical, energy, and other industries, making it a key equipment in these sectors.


  • Low rotating speed for stable operation
  • High component strength for durability
  • Convenient maintenance for ease of use
  • Compact size and lightweight for easy installation
  • Low noise operation for a comfortable working environment
  • Good sealing properties for efficient performance

The oil-free unloading ammonia LPG bog compressor is designed with a compressor, gas-liquid separator, filter, two-position four-way valve, safety valve, check valve, explosion-proof motor, and base. It utilizes air cooling for efficient cooling and has a maximum inlet pressure of 1.6MPa, outlet pressure of 2.4MPa, and maximum differential pressure of 0.8MPa. The maximum instantaneous pressure ratio is ≤4.

Piping and Instrumentation Diagram of gas unloading:

During the unloading process, the compressor pressurizes the gas from the storage tank and transfers it into the tanker through the gas phase line. Simultaneously, it presses the liquid from the tanker to the storage tank through the pressure difference of the gas phase. It is important to note that cooling the gas phase during pressurization is not necessary, as it may cause liquefaction and prolong the unloading process time. However, if residual gas recovery is required, a cooler can be used to expedite the process.

Liquid delivery:

To initiate the liquid delivery process, the liquid phase pipeline between the tanker and the storage tank should be opened. If the liquid level in the tanker is higher than the storage tank, the liquid will automatically flow into the storage tank until a balance is reached. If the liquid phase of the tanker is lower than the storage tank, the compressor can be started. The four-way valve should be in the positive position, allowing the gas to be extracted from the storage tank and discharged into the tanker. This process raises the pressure in the tanker and lowers the pressure in the storage tank, causing the liquid in the tanker to flow into the storage tank.

Surplus liquid recovery:

To recover surplus liquid, the four-way valve should be reversed after the liquid delivery process. The remaining gas in the tanker is then inhaled by the compressor, pressurized, and discharged into the storage tank until the pressure of the remaining gas drops to a negligible value. It is crucial to ensure that the compressor pressure ratio and exhaust temperature remain within the allowable values during the recycling process.
