Helium Recovery and Liquefaction

In order to attain high purity levels, helium must be recovered from the natural gas. Raw helium is recovered from natural gas in a cold box with a cryogenic process. Down-stream of the cold box, helium is further purified in a pressure swing adsorption (PSA) unit and liquefied for storage at temperatures of about -270 °C.

Linde Engineering offers a well proven cryogenic process for the production of high purity helium. Furthermore Linde Engineering is world leader in design and supply of PSA units. As a result of this combination of process design and equipment manufacturing capabilities Linde Engineering has accumulated a wealth of experience in designing and constructing helium production units all over the world.
