<p>The plant for gasification of coal into methane or synthetic gas comprises a hydrogenation gasifier (2), a vapour gasifier (4), a convertion (17) an fractionation (9) device. The coal to be gasified is first introduced into the hydrogenation gasifier, and then into the vapour gasifier wherein an almost complete gasification takes place. The crude gas coming from one gasifier is used to heat the other gasifier. The thermal energy required for the process comes from a nuclear reactor and is partly either in the form of electrical energy or in the form of vapour. The terminal part of the vapour gasifier has to be heated electrically so as to obtain the high temperature required for the process and yet this high temperature should not be allow for the reactor (23). Further, with such a process, the reactor may be separated and uncoupled from the gasification plant. When such a plant is used only for the production of synthesis gas, the upper part of the furnace for the separation of methane necessary in this case, with all the advantages mentions above, is also heated electrically. </p> |
