Linde AG, Engineering Division products

Hydrogen (H2) is produced by steam reforming, partial oxidation of hydrocarbons and by the conversion of carbon monoxide and purified by pressure swing adsorption or through the purification of refinery purge gases.

The combination of membrane and PSA technologies gives our customers new-found levels of flexibility and efficiency.

Natural gas typically contains a mixture of methane and heavier hydrocarbon gases, as well as carbon dioxide, nitrogen, water and a range of other unwanted components. Unwanted components must be removed, and the heavier hydrocarbons separated prior to liquefying and transporting natural gas. This involves a combination of pure adsorptive or absorptive and cryogenic processes - all of which are part of Linde Engineering`s core competencies.

LNG is natural gas in its liquid form. In order to liquefy natural gas, it must be cooled to cryogenic temperatures of approximately -160°C. As a liquid, natural gas occupies only 1/600 of the volume of natural gas (at atmospheric pressure) in its gaseous form and therefore allows for more economic and practical storage. It is also easer to transport over great distances.
