In the method applied today solid organic waste are treated in a salt and alkaline melt at a temperature of 400-900° C. The method includes delivery of solid organic waste and gases and removal of the products obtained in the processing. The said solid organic waste are fed in the melt together with an inert gas; the melt is then regenerated with an oxygen-containing gas.

In the newly-developed technology, preliminary treatment of solid organic waste is provided. Solid organic waste and gases are directed below the melt bed surface. Treatment of solid organic waste and regeneration of the melt are separated from each other and performed simultaneously. The melt temperature in the waste treatment process is increased; gases released in the waste treatment process and in the melt regeneration process are cleaned.

In the second modification of the newly-proposed method, solid organic waste, namely, cellulose materials, are processed with a 15-20% alkaline solution.

In the third modification of the newly-proposed method, melt temperature is increased proportionally to the carbonate accumulation in the said melt.

In the fourth modification of the newly-proposed method, hot flue gases released both in the waste treatment process and in the melt regeneration process interact with each other at a temperature of 700-900°C; mixed gases are then cleaned to remove nitrogen and sulphur oxides at a temperature of 400-450° C. A final cleaning up of organic waste from residual contamination is effected on a catalyst layer at the temperature of 450-500° C.

Installation for treating solid organic waste in a melt includes a disrupter, a supplementary-burning chamber, and a clean-up unit to remove sour gases and solid particles. In the newly-designed installation, the said supplementary-burning chamber contains a fluidized bed and is equipped with an inert nozzle; the said clean-up unit, required to remove sour gases and solid particles, is designed as a chemisorbent strained declining counterflow reactor (CSDCFR). Catalytic reactor and a heat exchanger are installed one after another downflow the CSDCFR.

A disrupter for treating solid organic waste in a melt includes a housing, a cover, reaction and regeneration pipes, sleeves to feed gas and waste and remove reaction products. In the newly-designed disrupter, the space over the melt under the cover is split in 3 zones separated from one another by partitions deepened in the melt. The sleeves for feeding gas and waste are placed in the melt and in combination with regeneration pipes form gas-lift reactors.

In the second modification of the disrupter, a gas-lift reactor with a reaction pipe is installed in the disrupter central part, while gas-lift reactors with regeneration pipes are placed at the peripheral parts.
