A gasification apparatus has a primary chamber with a floor comprising a hearth and feedstock augers, for gasification of feedstock. There is a mixing chamber for receiving through an opening synthetic gases from the primary chamber and comprising an air inlet fan for adding oxygen for ignition. There is also a secondary chamber linked with the mixing chamber to deliver heat from combustion of gases from the mixing chamber to the hearth. An outlet valve delivers gases from the secondary chamber through a heat exchanger and to an induce draft fan. A controller dynamically controls flow of gases in the chambers according to sensed pressures and temperatures in said chambers.

A method for controlling carryover in a chemical recovery boiler. The method comprises feeding black or brown liquor to a furnace of the chemical recovery boiler through an injection gun to burn the black or brown liquor. The chemical recovery boiler comprises a bullnose, which narrows the furnace, and a first superheater, of which at least a part is arranged at a higher vertical level than the bullnose. The method comprises measuring information indicative of a spatial temperature distribution on a cross section of the furnace, wherein the cross section is above the injection gun and below the first superheater; determining primary information indicative of carryover using the information indicative of the spatial temperature distribution on the cross section of the furnace; and controlling a temperature of the black or brown liquor that is fed to the furnace using the primary information. In addition, a system for performing the method.

Systems and methods include a computer-implemented method for providing flare header information. Instantaneous flaring flowrate data is received from flaring sources of a flare network of a processing facility. The instantaneous flaring flowrate data is analyzed in conjunction with physical properties of relief sources obtained from a heat and material balance of the processing facility. A heating value and a molecular weight are determined for each relief source and flare header using a processing model associated with a relief source type, size, and identifications. The relief sources are connected using a data signal received and processed using the processing model. Reports are generated showing average daily heating values and molecular weights for each flare header. A real-time display is provided for monitoring instantaneous heating values and molecular weights for each flare header on a real-time basis.

According to one aspect of the invention, a catalyst tower is provided, which comprises a gas inlet and a catalyst holding plate set therein. The gas inlet is the opening where the catalyst tower and the upstream piping connects with one another. The distance between the gas inlet and the catalyst holding plate is directly proportional to the difference in diameter between the catalyst tower and the upstream piping.

A regenerative thermal oxidizer assembly includes a first housing member and a second housing member. The first housing member defines a regenerative portion and a combustion chamber. The second housing member defines an inlet chamber and an outlet chamber. A regenerator is disposed within the regenerative portion of the first housing member and defines a central axial opening extending to the combustion chamber. A thermal element extends through the axial opening to the combustion chamber for providing heat to the combustion chamber for initiating combustion inside the combustion chamber. The first housing member is rotatable around an axis defined by the axial opening relative to the second housing member for rotating the regenerator relative to the inlet chamber and the outlet chamber.
