  • Publication number: 20250354687
    Abstract: A thermal oxidizer including an oxidation mixer, an oxidation chamber, and a retention chamber forming a fluid flow path for thermal oxidation of a waste gas. The thermal oxidizer also includes first and second electric heating elements. In operation, the first and second electric heating elements pre-heat portions of the thermal oxidizer. Once a threshold temperature has been reached, the oxidation mixer facilitates a combustible mixture of the waste gas and an oxidant into an combustible waste gas stream, the oxidation chamber facilitates a primary combustion reaction of the combustible waste gas stream into an oxygenated waste gas stream, the retention chamber facilitates a secondary combustion reaction of the oxygenated waste gas stream into oxidized gases and the heat dissipator reduces the temperature of the flow of oxidized gases within the heat dissipator.

  • Patent number: 12405003
    Abstract: A thermal oxidizer employing an oxidation mixer, an oxidation chamber, a retention chamber and a heat dissipater forming a fluid flow path for thermal oxidation of a waste gas. In operation, the oxidation mixer facilitates a combustible mixture of the waste gas and an oxidant into an combustible waste gas stream, the oxidation chamber facilitates a primary combustion reaction of the combustible waste gas stream into an oxygenated waste gas stream, the retention chamber facilitates a secondary combustion reaction of the oxygenated waste gas stream into oxidized gases and the heat dissipator reduces the temperature of the flow of oxidized gases within the heat dissipator, which is communicated to a greenhouse gas processor that extracts greenhouse gas(es) from the vaporized oxidized gases. The greenhouse gas processor may condensate the greenhouse gas(es), acid neutralize the condensation of the greenhouse gas(es), and capture the acid neutralization of the condensation of the greenhouse gas(es).

  • Patent number: 11391458
    Abstract: A thermal oxidizer (50) employing an oxidation mixer (51), an oxidation chamber (52), a retention chamber (53) and a heat dissipater (54) forming a fluid flow path for thermal oxidation of a waste gas. In operation, the oxidation mixer (51) facilitates a combustible mixture of the waste gas and an oxidant into an combustible waste gas stream. A heating element (55) of the oxidation chamber (52) facilitates a primary combustion reaction of the combustible waste gas stream into an oxygenated waste gas stream. The retention chamber (53) facilitates a secondary combustion reaction of the oxygenated waste gas stream into oxidized gases. The heat dissipater (54) atmospherically vents of the oxidized gases. An oxidization controller (61) may be employed to regulate the operation of the thermal oxidizer (50), and a data logger (63) and a data reporter (65) may be employed for respectively logging and remotely reporting a regulation of the thermal oxidizer (50) by the oxidation controller (61).
