Oil Free Ammonia Compressor propane compressor lpg gas compressor
Our company specialize in making various kinds of compressors, such as:Diaphragm compressor,
Piston compressors, LPG Compressor ,Air compressors,Nitrogen generator,Hydrogen generator,Oxygen generator ,gas cylinder,etc. Can be customized according to your parameters.
This ZW series of oil-free LPG compressors is one of the first products produced by our factory in China. The compressors have the advantage of low rotating speed, high component strength, stable operation, long service life and convenient maintenance. It is consist of compressor, gas-liquid separator, filter, two-position four-way valve, safety valve, check valve, explosion-proof motor and base etc. It has the characteristics of small size, light weight, low noise, good sealing, easy installation and easy operation.
This compressor is mainly used for unloading, loading, dumping, residual gas recovery and residual liquid recovery of LPG/C4, propylene and liquid ammonia. It is widely used in gas, chemical, energy and other industries, and is a key equipment in gas, chemical, energy and other industries.
Note: In the process of unloading, the compressor pressurizes the gas from the storage tank and then presses it into the tanker through the gas phase line, and presses the liquid from the tanker to the storage tank through the pressure difference of the gas phase to complete the unloading two process. When the gas phase is pressurized, the temperature of the gas phase will rise. At this time, it is not necessary to force it to cool, because if the gas phase is compressed and then
cooled, it is easy to liquefy, and the pressure difference of the gas phase is difficult to establish, which is not conducive to the replacement of the gas phase and the liquid phase. In short, it will prolong the unloading process time. If residual gas recovery is required, during the residual gas recovery operation, a cooler can be selected for forced cooling of the gas phase, so as to recover the residual gas as soon as possible.
The loading process is the opposite of the unloading process.

Inlet pressure:≤1.6MPa
Outlet pressure: ≤2.4MP
Max differential pressure: 0.8MPa
Maximum Instantaneous Pressure Ratio:≤4
Cooling method: Air cooling
The unloading volume is calculated according to the inlet pressure of 1.6MPa, the outlet pressure of 2.4MPa, the inlet temperature of 40 ºC , and the density of propylene liquid of 614kg/m3. When the working conditions change, the unloading volume will change accordingly, which is for reference only.
Liquid delivery
At the beginning, open the liquid phase pipeline between the tanker and the storage tank. If the liquid level in the tanker is higher than the storage tank, it will automatically flow into the storage tank. When the balance is reached, the flow will stop. If the liquid phase of the tanker is lower than the storage tank, directly start the compressor, the four-way valve is in the positive position, and the gas is extracted from the storage tank by the compressor and then discharged into the tanker. At this time, the pressure in the tank car rises, the pressure in the storage tank drops, and the liquid in the tank car flows into the storage tank. (as shown below) : 
Liquid recovery :
The residual liquid recovery process is the opposite of liquid transfer. After the liquid is delivered, the four-way valve should be reversed, and the dotted line in the figure is closed. At this time, the remaining gas in the tanker is inhaled by the compressor, pressurized and then discharged to the storage tank until the pressure of the remaining gas drops to no recovery value. When recycling, pay attention that the compressor pressure ratio and exhaust temperature cannot exceed the allowable values.
