Hydrogen and carbon monoxide impurities are removed from a dry gas comprising the impurities, wherein the dry gas is at least substantially free of carbon dioxide, by passing the dry gas with sufficient residence time, e.g. at least 1.5 s, through a layer of alyst comprising a mixture of manganese oxide and copper oxide. The use of expensive noble metal alysts to remove hydrogen may

Producing helium from natural gas

Helium is mostly extracted from natural gas. In Russia helium is produced exclusively by one company – the Orenburg Gas Processing Plant (GPP) that is a part of Gazprom dobycha Orenburg. The Orenburg oil and gas condensate field (OGCF) is fairly poor in helium: the volume fraction of this substance in the gas is only up to 0.055 per cent.
