Abstract: Environmentally harmful heterocompounds (harmful substances) of organic media which are or have been rendered free-flowing, as for example waste material or highly toxic material containing chlorinated hydrocarbon or sulphur, produced for example through distillation of chemical residues, dioxine and the like, and through recycling of waste material, where silting-up and incrustation occur during condensation, are separated and decomposed by a special process using a single-tube reactor. Harmful substances are thus separated below the cracking threshold and transformed into easily purifiable substances; alternatively, in certain cases, the media are heated beyond the cracking threshold, thus producing new substances, for example methane, propane and the like. The high risk of associated silting-up or incrustation, in particular during condensation, is avoided by using injection condensation, preferably fractional condensation.
