Description
Compact Upright Oil-Free LPG & Ammonia Unloading Compressor
Compact Reciprocating Compressor for LPG, Ammonia, Propane & Butane Unloading
The Compact Upright Oil-Free LPG & Ammonia Unloading Compressor is designed for the efficient and controlled unloading, transfer and recovery of LPG, ammonia, propane, butane and similar liquefied gases.
The compressor is suitable for integration into LPG unloading stations, chemical plants, gas storage facilities and industrial gas distribution systems, where reliable gas transfer is required during continuous industrial operation.
Featuring a reciprocating piston compression system with an oil-free compression configuration, the unit is designed to minimize contamination of the handled gas while providing stable compression performance.
Its compact upright structure makes it particularly suitable for installations where available floor space is limited, including unloading stations, storage facilities and industrial gas handling areas.
Product Overview
The compressor uses a reciprocating piston configuration designed for positive-displacement compression of liquefied gas vapors.
The oil-free compression arrangement supports applications where maintaining gas cleanliness and minimizing contamination are important considerations.
Its upright construction provides a compact equipment arrangement and allows the compressor to be incorporated into different unloading and transfer system layouts.
Typical applications include:
- LPG tanker unloading
- Ammonia unloading
- Propane and butane transfer
- Gas storage transfer
- Cylinder filling systems
- Residual gas recovery
- Industrial liquefied gas handling
Key Features & Advantages
Oil-Free Compression
The compressor incorporates an oil-free compression system designed to minimize oil contamination of the handled gas.
This configuration is suitable for applications where gas purity and clean compression are important process considerations.
Compact Upright Design
The upright construction provides a space-efficient equipment arrangement, making the compressor suitable for installations with restricted floor area.
It can be integrated into unloading stations and industrial gas facilities where efficient equipment placement is required.
Suitable for Multiple Liquefied Gases
The compressor can be configured for applications involving:
- LPG
- Ammonia
- Propane
- Butane
- Similar compatible liquefied gas media
Gas compatibility should be confirmed according to the actual gas composition, pressure, temperature and material requirements of the application.
Stable Continuous Operation
The reciprocating piston configuration is designed to provide stable gas transfer performance for continuous industrial processes, subject to the specified operating conditions and system design.
Flexible Drive Configurations
The compressor can be supplied with different drive and lubrication arrangements depending on the application and project requirements.
Available configurations include:
- Belt drive with splash lubrication
- Direct drive with splash lubrication
- Belt drive with oil pump lubrication
- Direct drive with oil pump lubrication
The final drive arrangement can be selected according to operating conditions, maintenance preferences, installation requirements and project economics.
Drive System Options
Belt Drive – Splash Lubrication
A belt-driven configuration with splash lubrication can provide a flexible mechanical arrangement where equipment layout and drive configuration need to be adapted to the installation.
Direct Drive – Splash Lubrication
The direct-drive configuration provides a more direct power transmission arrangement and can be considered where the installation layout permits.
Belt Drive – Oil Pump Lubrication
For applications requiring pressure lubrication, an oil-pump lubrication configuration can be provided with a belt-driven arrangement.
Direct Drive – Oil Pump Lubrication
A direct-drive configuration combined with oil-pump lubrication provides another option for projects where the selected operating conditions require this arrangement.
The appropriate configuration should be determined according to the compressor design, operating conditions and project-specific requirements.
Applications
The Compact Upright Oil-Free LPG & Ammonia Unloading Compressor can be used in a variety of liquefied gas handling applications, including:
LPG Tanker Unloading
Used in systems designed to transfer LPG from tank trucks or transport vessels to storage tanks through a controlled gas-pressure transfer process.
Ammonia Unloading
Suitable for integration into ammonia unloading systems where controlled transfer between transportation equipment and storage facilities is required.
Gas Storage & Transfer Stations
The compressor can support gas transfer between storage vessels and process equipment in industrial gas storage and distribution facilities.
Cylinder Filling Operations
Can be incorporated into suitable cylinder filling and gas handling systems for controlled transfer of LPG and compatible liquefied gases.
Residual Gas Recovery
The compressor can be used in recovery systems designed to collect and transfer residual gas from vessels, pipelines and process equipment.
Typical Installation Areas
The compressor is suitable for applications in:
- LPG unloading stations
- LPG storage terminals
- Gas distribution facilities
- Chemical plants
- Petrochemical facilities
- Industrial gas storage systems
- LPG cylinder filling plants
- Ammonia storage and handling facilities
- Gas transfer stations
- Liquefied gas processing facilities
Customization Options
The compressor can be configured according to the specific requirements of the unloading or transfer system.
Customization considerations may include:
- Gas type
- Gas composition
- Required flow rate
- Suction pressure
- Discharge pressure
- Operating temperature
- Installation space
- Drive configuration
- Motor power
- Lubrication arrangement
- Control and instrumentation
- Process piping integration
- Safety and protection requirements
Each compressor configuration can be selected according to the actual industrial unloading and gas-transfer conditions.
Safety & Process Considerations
LPG, ammonia, propane and butane require appropriate safety engineering because of their respective flammability, toxicity, pressure and volatility characteristics.
The complete installation should be evaluated for appropriate:
- Pressure relief systems
- Gas-tight piping and connections
- Isolation valves
- Gas detection systems
- Emergency shutdown arrangements
- Adequate ventilation
- Appropriate electrical equipment for the hazardous area
- Grounding and bonding
- Pressure and temperature monitoring
- Gas-compatible seals and materials
For ammonia applications, additional measures should be considered for toxic gas detection, ventilation and personnel protection.
The final compressor configuration should be selected according to the actual gas medium, process conditions, applicable standards and project-specific safety requirements.
