  • Publication number: 20240010941
    Abstract: The present invention relates to a process and an installation for the continuous flow of gasification of heterogeneous mixtures of organic substances and compounds such as biomass waste, forestry, municipal solid and liquid waste, sludge from sewage treatment plants and other similar waste. Presentation Of The Invention: The process according to the invention has the following steps: a) the organic raw material in heterogeneous mixture is introduced into the pyrolysis reactor (2) where it is gradually heated, by forced convection and thermal radiation, to a temperature of 900 . . . 1000° C., being kept in contact with metal surfaces that transport thermal energy through conduction from the exothermic area of the gasification reactor. The metal surfaces are placed in fixed positions, different so that the contact surface changes after 5 . . . 20 cm traversed by the flow of organic raw material, each group of metal slats forming 2 . . .

  • Publication number: 20140157789
    Abstract: 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.
