A regenerative thermal oxidizer (RTO) with three or more chambers. Each chamber would be in a unique mode, (inlet, outlet, purge). Each chamber has its gas flow determined by two poppet valves which define which mode the chamber will be in: inlet mode, output mode, or purge mode.

Methods and systems for oxidizing gas are provided. An example regenerative oxidizer is provided that includes a combustion chamber to heat gas present in the combustion chamber. The regenerative oxidizer also includes a first heat exchange media bed and a second heat exchange media bed. Each of the first heat exchange media bed and the second heat exchange media bed are in fluid communication with the combustion chamber. The regenerative oxidizer further includes two burners disposed within the combustion chamber to provide a total heat input to the gas present in the combustion chamber. At least one of the two burners is independently adjustable based on the airflow direction.

This invention deals with an emission capture device with grease which is composed of a main duct, here it is connected to the outlet of the emitter of particles which are required to be treated (said emitter is conventional, such as an internal combustion engine exhaust, incinerator duct, meat roaster chimney, etc. Just to mention a few), it is then absorbed and propelled by an electric fan, from which its wind force drives the emissions into the emissions capture tank, the mechanism to dissolve the particulate emissions inside the tank is composed of, The mechanism to dissolve the emission particles inside the tank is composed of the main duct inside the tank, which reaches the upper part of the tank, making a spiral return to the lower part of the tank, having the main duct as its end, through which the emission already dissolved in the liquid comes out, between the mechanism to dissolve the emission and the walls of the tank it has four supports, in the upper part of the tank it has its outlet duct to the open air, it also has four liquid inlet ducts, At the bottom of the tank there are two outlets to drain the liquid and direct it to a cooling device, and from there it is transported through a duct to a decanter tank, which in its lower part has a decanter tank, and at the same time it is transported to the bottom of the tank, On one side of the decanter tank is a duct that is connected directly to a pump that is responsible for driving and supplying the liquid through its outlet duct directly to the ducts that are responsible for distributing the liquid to the emissions capture tank and its mechanism to dissolve the emissions that are treated there.

A method for burning primary fuel (F1), wherein the primary fuel (F1) comprises at least a first compound containing nitrogen and a second compound comprising sulfur. The method comprises producing primary combustion gas (G1) having a temperature of at least 450° C. and comprising oxygen; feeding the primary fuel (F1) and the primary combustion gas (G1) to a primary process zone (Z1) of a furnace (200); feeding tertiary combustion gas (G3) to a secondary process zone (Z2) of the furnace (200); letting the primary fuel (F1), the primary combustion gas (G1), and/or their reaction products to move from the primary process zone (Z1) via the secondary process zone (Z2) to a tertiary process zone (Z3) of the furnace (200); and feeding quaternary combustion gas (G4) comprising oxygen to the tertiary process zone (Z3) of the furnace (200). An embodiment comprises collecting the primary fuel (F1) from a pulp process. A corresponding system.

The disclosure is directed to a process and an apparatus for recovering energy from the low energy density waste gas stream. The process and the apparatus allow a thermal oxidizer to oxidize the low energy density waste gas stream using a low energy density fuel gas such as syngas, BF gas, or biogas without the need for auxiliary high energy density sources.

A method and apparatus which provides the ability to capture natural gas which would otherwise be vented from control valves and use the captured natural gas to power a low pressure pilot light of a burner and/or to power a natural gas engine. In one embodiment, the captured natural gas can be supplemented with an additional supply of natural gas to ensure operation of the pilot and/or natural gas engine in the even that the captured natural gas is not sufficient to provide continuous power of the pilot and/or engine. Optionally, the captured natural gas can be sequestered in a storage vessel.

A device and system for energy generation using plasma incineration and further, for producing electricity by hydrogen gas generation and combustion.
