Abstract:
A process is provided for treating a liquid effluent from a gas to liquid conversion reactor. A synthesis gas is initially converted to a liquid hydrocarbon phase in the gas to liquid conversion reactor. The liquid hydrocarbon phase includes a heavier liquid paraffinic wax compound and a lighter liquid paraffinic compound. The liquid hydrocarbon phase is discharged from the gas to liquid conversion reactor in a reactor effluent and an abrasive solid particle medium is entrained in the reactor effluent to form a fluidizable mixture. The reactor effluent is conveyed past a heat transfer surface which is cooler than the reactor effluent. The fluidizable mixture is contacted with the heat transfer surface and the liquid hydrocarbon phase is cooled to a temperature below the melting point of the heavier liquid paraffinic wax compound. Consequently, the heavier liquid paraffinic wax compound is converted to a plurality of unconsolidated solid wax particles. A slurry is formed from the plurality of unconsolidated solid wax particles and the remaining lighter liquid paraffinic compound.
Abstract:
A process for reducing nitrogen monoxide emissions when burning solid fuels, in which the whole of the solid fuel is degassed prior to ignition in an output power combustion zone (2). At least one part of the gas obtained from degassing of the solid fuel is used as a reduction gas in one or several reduction zones (3) arranaged downstream of the power combustion zone (2). In a plant for performing the process, the installation for degassing the solid fuel is arranged as a degassing section(s) designed for a continuous throughflow of fuel and located inside the combustion chamber (1) in the flue gas flow.

Abstract:
A dark radiator includes a first burner, a fan and a radiant tube. The first burner is connected to a fuel gas supply, the fan is designed to supply the first burner with combustion air and the first burner is designed to output a flame into the radiant tube. The fuel gas supply is connected to a hydrogen source as a fuel gas source and a secondary burner is connected downstream in the radiant tube spaced apart from the first burner functioning as the primary burner in the flame direction. The fuel gas supply thereof is connected to a hydrogen source as a fuel gas source and the exhaust gas flow of the upstream primary burner is supplied to the secondary burner as combustion air.
Abstract:
The present invention relates to a combustion heater (100) for providing controlled heat (H) to an endothermic reaction process. The combustion heater comprises an integrated burner (20) to yield a hot burner exhaust gas (35) flow from burning a first fuel. The burner exhaust gas mixed with oxidant flows to a flue gas outlet along a flue gas flow path (FGP). Provided to the combustion chamber at a position outside a direct reach of flames from the burner is a secondary fuel conduit (30) with a plurality of nozzles (31) from which a second fuel (32) is transferred into a flow along the said flue gas flow path (FGP). The resulting combustion of the second fuel can be used to provide controlled heat to the to endothermic reaction operated in a reaction conduit (40) that is in thermal heat exchange with the combustion chamber.
Abstract:
According to embodiments, a co-fired or multiple fuel combustion system is configured to apply an electric field to a combustion region corresponding to a second fuel that normally suffers from poor combustion and/or high sooting. Application of an AC voltage to the combustion region was found to increase the extent of combustion and significantly reduce soot evolved from the second fuel.
