Thermodynamic cycles with diluent that produce mechanical power, electrical power, and/or fluid streams for heating and/or cooling are described. Systems contain a combustion system producing an energetic fluid by combusting fuel with oxidant. Thermal diluent is preferably used in the cycle to improve performance, including one or more of power, efficiency, economics, emissions, dynamic and off-peak load performance, temperature regulation, and/or cooling heated components. Cycles include a heat recovery system and preferably recover and recycle thermal diluent from expanded energetic fluid to improve cycle thermodynamic efficiency and reduce energy conversion costs. Cycles preferably include controls for temperatures, pressures, and flow rates within a combined heat and power (CHP) system, and controls for power, thermal output, efficiency, and/or emissions.

Thermodynamic cycles with thermal diluent

Combustion gases with relatively high levels of carbon dioxide (CO), steam, and/or hot water, may be used to improve recovery of heavy hydrocarbons from geologic formations and/or from surface mined materials. These gases reduce the viscosity and/or increase hydrocarbon extraction rates through improvements in thermal efficiency and/or higher rates of heat delivery for a given combustor an capital investment. Such high water/COcontent combustion gases can be formed by adding water to combustion gases formed by burning fuel. The pressure to inject the combustion gases and extract heavy hydrocarbons may be provided by diverting high pressure expanded gases from wet combustion in a gas turbine, or by reducing the pressure drop across a turbine and using the expanded hot gases for extraction.

Hot fluid recovery of heavy oil with steam and carbon dioxide

A thermally diluted exothermic reactor system is comprised of numerous orifices distributed within a combustor by distributed perforated contactor tubes or ducts. The perforated contactors deliver and mix diluent fluid and one or more reactant fluids with an oxidant fluid. Numerous micro-jets about the perforated tubes deliver, mix and control the composition of reactant fluid, oxidant fluid and diluent fluid. The reactor controls one or more of composition profiles, composition ratio profiles and temperature profiles in one or more of the axial direction and one or two transverse directions, reduces temperature gradients and improves power, efficiency and emissions.

Trifluid reactor

A remediation system for decontaminating a polluted site that delivers a remediation fluid to the polluted site and receives a contaminated effluent from the polluted site. The system includes a reactor that receives the contaminated effluent and generates an exit fluid stream and a first flow control mechanism coupled to the outlet of the reactor that releases a controlled portion of the exit fluid from the system, and delivers the remaining portion of the exit fluid as the remediation fluid, or delivers the remaining portion to a second flow control mechanism for combination with a controlled quantity of the second reactant to form the remediation fluid.

Thermogenerator to remediate contaminated sites

A thermodynamic system that produces mechanical, electrical power, and/or fluid streams for heating or cooling. The cycle contains a combustion system that produces an energetic fluid by combustion of a fuel with an oxidant. A thermal diluent may be used in the cycle to improve performance, including but not limited to power, efficiency, economics, emissions, dynamic and off-peak load performance, and/or turbine inlet temperature (TIT) regulation and cooling heated components. The cycle preferably includes a heat recovery system and a condenser or other means to recover and recycle heat and the thermal diluent from the energetic fluid to improve the cycle thermodynamic efficiency and reduce energy conversion costs. The cycle may also include controls for temperatures, pressures, and flow rates throughout the cycle, and controls power output, efficiency, and energetic fluid composition.

Thermodynamic cycles using thermal diluent

Diluted wet combustion forms a hot process fluid or VASTgas including carbon dioxide (CO) and fluid water which is delivered to geologic formations and/or to surface mined materials to reduce the viscosity and/or increase hydrocarbon extraction. High water and/or COcontent is achieved by reducing non-aqueous diluent and/or adding or recycling CO. Power recovered from expanding the VASTgas may be used to pressurize the VASTgas for delivery by partial expansion through a Direct VAST cycle, and/or by diverting compressed oxidant through a parallel thermogenerator in a Diverted VAST cycle. Pressurized VASTgas may be injected into a well within the hydrocarbon formation or with mined material into a heavy hydrocarbon separator vessel to heat, mobilize, solubilize and/or extract heavy hydrocarbons. Light hydrocarbons may be mixed in with the hot process fluid to enhance hydrocarbon mobilization and recovery. Microwaves may further heat the VASTgas and/or hydrocarbon. Sulfur oxidation, calcining limestone and/or recycling may increase CO. Oxygen enrichment may increase the specific power. VASTgas may be delivered through and back injection wells and/or production wells, and/or between sequential injection wells in alternating and/or paired zigzag formations with multiple wells per VAST combined heat and power recovery system.
