(FR2679009-A1)      In an industrial and/or domestic waste treatment process involving drying, thermolysis and dechlorination of the thermolysed solids by washing, thermolysis is effected by direct contact of the waste with hot gas having a low oxygen content pref. of less than 10 (esp. less than 4) vol. %.    In an installation comprising a thermolysis unit (4) fed (partly) with thermolysis waste gas or its combustion waste gas, a hot combustion gas generator (19) and a solid thermolysis prod. collecting and washing unit, the novelty is that: (i) the thermolysis unit has a waste inlet and a hot thermolysis gas inlet and outlet (25); and (ii) the hot gas and the waste are in direct contact within the thermolysis unit.    USE/ADVANTAGE -   For waste thermolysis to produce an easily reusable clean coke. Compound with indirect heating processes, the process is simpler, has reduced sealing problems, has lower energy consumption, can use a smaller thermolysis unit and gives increased yield of usable coke    (EP524847-B1)      Method of treating industrial and/or household waste, comprising in particular a drying stage, a stage of thermolysing the waste by brining the waste into direct counter-flow contact with warm gases, characterised in that the thermolysis process is followed by a stage of dechlorination by washing the solids produced during thermolysis.    (US5505822-A)      A process for treating industrial and/or urban waste, comprising the following steps: (i) drying the waste in a drier; (ii) effecting thermolysis of the dried waste by direct contact with warm gases in a reactor to produce solids and gaseous effluents; (iii) washing the solids resulting from the thermolysis with water to effect dechlorination of the solids; (iv) combusting part of the gaseous effluents resulting from the thermolysis in a gas generator device for generating warm gases; and (v) heating and then recycling part of the gaseous effluents resulting from the thermolysis to the reactor; where thermolysis is effected by counter-current flow between the waste and the warm gases in direct contact in the reactor, at least a part of the warm gases in the reactor comprising the gaseous effluents recycled to the reactor; a part of the gaseous effluents issuing from the reactor is introduced into the gas generator device as fuel for generating warm gases; and at least a part of the warm gases generated by and discharged from the gas generator device is used for drying the waste in the drier.    (US5616216-A)      A plane for treating industrial and/or urban waste comprising: a means for the thermolysis of the waste, supplied at least partly by the thermolysis effluents or by effluents from the combustion of the thermolysis effluents and having separate outlets for the thermolysis solids and effluents,    a means for generating warm fumes, a means for collecting and washing the solid products coming from thermolysis means,    wherein the thermolysis means comprises at least one inlet for the waste, at least one inlet and one outlet for warm thermolysis gases and wherein the waste and the warm gases are in direct contact in the thermolysis means.
