Abstract: A process for the manufacture of a useful product from carbonaceous feedstock of fluctuating compositional characteristics, the process comprising the steps of: continuously providing the carbonaceous feedstock of fluctuating compositional characteristics to a gasification zone; gasifying the carbonaceous feedstock in the gasification zone to obtain raw synthesis gas; sequentially removing ammoniacal, sulphurous and carbon dioxide impurities from the raw synthesis gas to form desulphurised gas and recovering carbon dioxide in substantially pure form; converting at least a portion of the desulphurised synthesis gas to a useful product. Despite having selected a more energy intensive sub-process i.e. physical absorption for removal of acid gas impurities, the overall power requirement of the facility is lower on account of lower steam requirements and thereby leading to a decrease in the carbon intensity score for the facility.

Abstract: In a method for physical and thermochemical treatment of biomass, the biomass moisture content is reduced in a dryer and ammonia (NH3) is also released from the biomass during drying. The dried biomass is then either pyrolyzed in a pyrolysis reactor and the pyrolysis gas is forwarded to and combusted in a combustion device to form flue gas, or is combusted in a combustion facility unit to form flue gas. In either case the flue gas is fed to a mixer. Oxygen (O2) is metered to the flue gas in the mixer and is fed directly to the dryer as drying gas. As the drying gas passes through the dryer, the sulfur dioxide (SO2) contained in the drying gas and/or the sulfur trioxide (SO3) chemically reacts with the ammonia (NH3) to form ammonium sulfite ((NH4)2SO3) and/or ammonium sulfate ((NH4)2SO4). Also a treatment facility physically and thermochemically treats the biomass.

Abstract: Apparatus and methods to eliminate PFAS from wastewater biosolids through fluidized bed gasification. The gasifier decomposes the PFAS in the biosolids at temperatures of 900-1800° F. Syngas exits the gasifier which is coupled to a thermal oxidizer and combusts at temperatures of 1600-2600° F. This decomposes PFAS in the syngas and creates flue gas. Heat is recovered from the flue gas by cooling the flue gas to temperatures of 400-1200° F. in a heat exchanger coupled with the thermal oxidizer. Various methods inject moisture into the gas stream, controlling temperature through evaporative cooling and/or injecting chemicals that react with gas stream components. Cooled flue gas mixes with hydrated lime capturing decomposed PFAS molecules with spent lime filtered from the cooled flue gas using a filter system that may incorporate catalyst impregnated filter elements, eliminating PFAS from wastewater biosolids and controlling emissions in the resulting flue gas.

Abstract: An apparatus, a system, and a method for heat treating a moisture-containing or water-laden material are provided. The heat treatment can be drying for dehydration, gasification, or full carbonization. The system comprises a feeding mechanism, and a rapid compression unit (RCU) apparatus having a screw, a barrel, and one or more flow disrupters. The system can further include a reflux condenser, an aftercooler stage, a second condenser for particle filtering, and an exit mechanism. The one or more flow disrupters are located on an inner surface of the barrel and project into the passageway created by the screw and the barrel. The screw is sized to fit within the barrel such that flow disrupter does not contact the screw. The one or more flow disrupters cause the water-laden material to fold over onto its self, thereby, allowing for the occurrence of more uniform drying.

Abstract: A modular power generation system including a gasification reactor is disclosed for converting fuel, such as, but not limited to, biomass, to syngas to replace petroleum based fuels used in power generation. The system may include a reactor vessel with distinct reaction zones that facilitate greater control and a more efficient system. The system may include a sealing system for a continuous feed system of a gasifier enabling an inlet opening of a feedstock system to remain open yet seal the reactor without a mechanical system. The system may include a syngas heater channeling syngas collected downstream of the carbon layer support and to the pyrolysis reaction zone. The system may also include a syngas separation chamber configured to produce clean syngas, thereby requiring less filtering. The system may further include an agitator drive assembly that prevents formation of burn channels with in the fuel.
