Description

The main function of the truck unloading compressor is to raise the pressure of the gas during transportation by compression, enabling the unloading, loading, and recycling of gases. It is especially suitable for ammonia, liquefied petroleum gas (LPG), propylene, and other gases. As a special piece of equipment for gas unloading and compression, it is widely used in chemical plants, energy stations, the gas industry, and more. This compressor is crucial for industrial transportation processes, particularly for ammonia compression, unloading, and recycling. Its design emphasizes high performance, low noise, and easy maintenance.

Features of Truck Unloading Compressor

  1. Oil-free lubrication design: Ensures gas is not contaminated by oil, particularly suitable for ammonia and other applications requiring strict gas quality.
  2. Low speed and high component strength: Low-speed operation reduces wear and allows for stable long-term operation.
  3. Stability and reliability: Equipped with multiple safety protection measures to ensure stable performance under complex conditions.
  4. Simple structure, easy to maintain: Compact structure makes maintenance easy, reducing failure rates and maintenance costs.
  5. Low noise, good sealing: Advanced sealing technology reduces noise and provides a comfortable operating environment.
  6. Wide application: Suitable for unloading operations and other gas treatment processes in chemical, energy, and related industries.

The Working Principle of Truck Unloading Compressor

The compressor works on the principle of gas compression and pressure difference. During unloading, gas is sucked in and pressurized. Although the gas temperature rises during compression, no forced cooling is applied to avoid liquefaction, which could affect unloading efficiency. The pressurized gas enters the tanker via the gas phase pipeline, and the liquid is pushed from the tanker to the storage tank by the pressure difference, completing the unloading operation.
Throughout the process, inlet and exhaust pressures change but the exhaust pressure always stays above the storage tank pressure. Typical discharge pressures range from 0.2 MPa to 1.6 MPa, with inlet pressures from 0.1 MPa to 1.0 MPa and discharge volumes from 10 to 20,000 NM³/H. For residual gas recovery, forced cooling via a cooler may be used to speed up recovery.

Application Areas of Truck Unloading Compressor

  1. Chemical industry: Used for unloading, loading, and gas recovery of liquid ammonia, LPG, propylene, and other chemical gases. Essential for fertilizer plants, gas production facilities, and more.
  2. Energy industry: Supports transportation and recovery of natural gas and other gases, ensuring efficient energy storage and reduced waste.
  3. Electric power industry: Plays a key role in gas recovery for power plants, ensuring stable gas compression, storage, and transportation.
  4. Gas industry: In gas stations and pipeline transport systems, it increases gas pressure to support long-term storage and distribution.
