Linde has the know-how and the experience to plan, design, supply and construct complete plants for the production of hydrogen, carbon monoxide and mixtures of these two gases (synthesis gas) as well as ammonia and methanol from the feedstocks: natural gas, liquid gas, naphtha, residual oil and coal.
Hydrogen (H2) is produced by steam reforming, the partial oxidation of hydrocarbons and by conversion of carbon monoxide and then purified by pressure swing adsorption, or by the purification of refinery purge gases.
Linde plants supply H2 with a purity of up to 99.9999 vol.-% and a capacity of from 1,000 Nm³/h to 200,000 Nm³/h. H2 is utilized in its capacity as reactive gas in many hydrogenation processes, as a feedstock for the production of fertilizers, fuels and peroxide products or as an energy carrier.
Carbon monoxide (CO) is generated by steam reforming or partial oxidation of hydrocarbons and then purified by CO2 washing and low-temperature rectification. Linde plants supply CO with a purity of up to 99.99 vol.-% and a capacity of from 100 Nm³/h to over 30,000 Nm³/h.
CO is used to produce acetic acid or raw materials for the production of polyurethane and polycarbonate.
Synthesis gas (syngas, oxogas), a mixture of H2 and CO, is produced by steam reforming or partial oxidation of hydrocarbons or by a combination of both processes (tandem reforming). The desired ratio of H2 to CO can be adjusted by CO conversion or H2/CO separation.
Linde plants supply syngas with a capacity of from 1,000 Nm³/h to over 100,000 Nm³/h. Syngas is used for the production of oxo alcohols, methanol or synthetic fuels (Fischer-Tropsch products).
Ammonia (NH3) is produced from nitrogen and hydrogen in accordance with the LAC™ process or the high-pressure process with air fractionation and steam reforming or the partial oxidation of hydrocarbons.
Linde plants supply NH3 with a capacity of from 100 metric tons per day (mtd) to over 1,350 mtd. Ammonia is used for the production of fertilizers, nitric acid or urea.
Methanol (CH3OH, MeOH) is produced from synthesis gas, treated by steam reforming or partial oxidation of hydrocarbons or a combination of both processes (tandem reforming). The synthesis gas is converted into methanol in a Linde isothermal reactor.
Linde plants supply methanol with a capacity of from 100 mtd to over 1,000 mtd.
Methanol is used for the production of formaldehyde, acetric acid, MTBE, as a solvent or as an energy carrier.
