This invention relates to a process and installation for plasma heat treatment of a gas mixture for its use in thermal and electric power generation plants. According to the invention, the procedure consists in the feeding of a cylindrical reaction room with a gas mixture divided into at least two different flows, tangentially to the direction of a jet of plasma, so as to create a vortex around the jet of plasma, followed by the decrease of the primary gas speed by its expansion in a chamber with increased volume and area; cooling of the primary gas to a temperature of 800 . . . 1000° C. due to endothermic reactions, solidification and gravity separation from the cooled primary gas of vitrified inorganic particles; the cooling of the primary gas up to 60° C. followed by its barbotage into a NaOH solution to remove unwanted chemical elements, resulting in a final gas mixture, and the transport of the final gas mixture thus obtained, to end user to produce heat energy and electricity. The installation corresponding to the procedure according to the invention consists of a reactor ( 1 ) formed of a cylindrical room ( 2 ) with an intake system ( 3 ) to treat gas and a plasma cannon ( 4 ), an expansion room ( 5 ) provided with a hydraulic lock ( 6 ), for the evacuation of vitrified materials and a discharge outlet ( 7 ) of the treated gas to a heat exchanger ( 8 ) for cooling the resulted gas, a scrubber ( 9 ) for chemical treatment of gas, a CO 2 analyzer ( 10 ) and a gas-moving system ( 11 ) for its delivery to the equipment ( 12 ) for producing cogeneration/trigeneration electricity. |
