Compressor units for unloading and loading of liquefied gases

  • Compressor units for unloading and loading of liquefied gases
  • Compressor units for unloading and loading of liquefied gases

Compressor units COOLTECH are designed to perform operations of loading liquefied industrial gases, such as ammonia, propane, propylene, etc., into railway and road tank cars or unloading liquefied gases from them with residual vapours removal.

The loading or unloading process is provided by compressor unit creating necessary pressure difference in a railway or road tank car and facility technological (storage) reservoir.

  • Description
  • Execution
  • Completed projects

The liquefied gas unloading process is carried out as follows:

Compressor unit sucks off industrial gas vapors from facility technological (storage) reservoir, into which the liquefied gas is unloaded (received), and discharges them into a railway or road tank car from which the unloading is made. Due to the pressure difference, the liquefied gas is transferred from the tank car to the storage reservoir.

After liquid unloading from the tank car there is performed operation to remove residual vapors. To do this, using special valves, liquid drain line from the tank car is automatically shut off, compressor suction line is connected to the tank car, and discharge line to the storage reservoir. Compressor unit sucks off residual gas vapors and feeds them into the storage reservoir under liquid layer to prevent pressure build-up.

The liquefied gas loading process is carried out as follows:

Compressor unit sucks off industrial gas vapors from a railway or road tank car, into which the liquefied gas is loaded (shipped), and discharges them into facility technological (storage) reservoir from which the loading is made. Due to the pressure difference, the liquefied gas is transferred from the storage reservoir to the tank car.

  • Each station is designed on the basis of screw or piston compressor.
  • At the Customer’s request, compressor unit shall be manufactured in container or block-modular (block-box) version.
  • Compressor station includes compressor and auxiliary equipment (including heat exchangers) with installed shut-off and control valves and automated monitoring and control system.

Production of industrial gas compressor units, compressor units, chillers, pump circulating stations, air purgers, refrigeration and freezing systems of any complexity.
