Abstract
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.
