The installation has both a hydrogenating coal-gasifier (1) and a methane-decomposition furnace (6), the latter preferably being heated by a high temperature nuclear reactor (25). The two gas mixtures obtained from the gasifier (1) and the furnace (6) are freed of carbon dioxide, and, when mixed, are supplied to a methanol- synthesis reactor (11). The methanol produced is separated in a separator (13) from the gas, and the latter is separated in a low temperature separation process (14) into its components. The hydrogen flows back to the gasifier (1) and the methane to the furnace (6), whilst the nitrogen is removed and the carbon monoxide is conveyed back to the reactor (11). By integration, the amount of hydrogen conveyed in the installation is greatly reduced, which leads to savings in piping, pumps, etc. The heating fluid emerging from the furnace (6) can be used to heat a steam producer (19) in the lower temperature range, with which vapour a turbo-generator (20, 21) is driven. Leakage steam is supplied to the furnace (6) from the turbine (20). |
