FIELD: purification from resin. SUBSTANCE: contaminated gas fuel is introduced to a separate shaft-type reactor having a circulating fluidized bed of finely divided calcium and magnesium carbonate preferably in the form of dolomite or its sintering products. The gas to be purified goes to work as fluidizing agent. Purification is performed at a temperature of 600 - 1000 C. The fluidized bed density averages 80-250 kg/m3. After reactivating due to carbon precipitation the material is withdrawn and activated. Activation is conducted by a an oxygen-containing gas and/or steam at a temperature of 600 - 1000 C. The velocity of the gas flow in reactor is preferably below 10 m/s residence time of gas in reactor ranging from 0.2 to 20 s. When purified the gas fuel is cooled to 150 - 300 C and dedusted. The residual contents of resin and ammonia gas varies from 500 to 300 mg/m3 respectively. After purification HCL concentration is lowered to thermodynamic balance level. EFFECT: increased efficiency of process. 6 cl, 1 dwg
