In a process and an apparatus for purifying flammable gas, in particular low-temperature carbonization gas, the gas is scrubbed and discharged as pure gas and condensate. The condensate is distilled in a distillation unit. Volatile constituents are admixed to the pure gas, so that the calorific value of the latter is increased. The non-volatile constituents are discharged. The non-volatile constituents can be fed to a low-temperature carbonization drum and carbonized therein at low temperature.

Process and apparatus for purifying flammable gas

In a process and an apparatus for disposing of waste, the waste is carbonized at low temperatures in a carbonization drum, to develop carbonization gas and solid carbonization residue. The carbonization gas is burnt in a combustion chamber and the carbonization residue is divided in a separation device into a coarse and a fine fraction. The fine fraction is subjected to a gasification in a gasifier, to develop synthesis gas and molten slag. A temperature within the gasifier is above a melting temperature of non-combustible substances introduced into the gasifier. The synthesis gas is burnt in the combustion chamber or in a combustion chamber of a gas engine.
