Low Pressure Helium Gas Recovery


The low pressure Helium recovery system is used in situations where the recovered gas is a) to be reliquefied or b) reused in some other low pressure process. The typical pressure is around 10 barg. As long as the gas generation is slower than the recovery compressor pumping speed, this process requires no gas buffer reservoir before the compressor.

Quantum is one of the very few suppliers to offer an all-metal low-pressure Helium recovery system. The main advantage of this system is that it avoids the contamination of the recovered gas, rendering unnecessary the need for purification. In this system the compressor is designed to run continuously.

Quantum designs solutions for each particular application/set-up, regardless of the size and needs. We can either propose an off-the-shelf design, or an adapted solution to best fit your current, future process at the optimum CAPEX and OPEX.

Description of System

The components of a typical low pressure recovery system are:

  1. Recovery Compressor - Low Pressure Compressor, including manifold to ensure inlet does not draw a vacuum.
  2. Q09.4-J20-MAN - Manifold between compressor inlet and outlet to ensure inlet is above 1 atm (require enough tanks to store all the helium in the system.)
  3. Q09.4-TANK-He-450 - Low Pressure Steel Helium Storage Tank(s), 450 L each (regulator to control pressure of helium returning to process.)
  4. Q09.4-TANK-MAN - Manifold for distributing recovered gas to storage tanks
  5. Q11.4-TC-20 - OPTIONAL: Helium Gas Purity Meter to monitor gas contamination.
  6. Helium Purifier - (NOT PART OF THE TYPICAL RECOVERY SYSTEM) - for situations where the process contaminates Helium.
  7. Helium Liquefier - (NOT PART OF RECOVERY SYSTEM) For example, Q01.1-4310 Liquefier to convert helium gas to liquid before returning to Process.
