METHOD AND ARRANGEMENT FOR RECOVERING ENERGY AND CHEMICALS

摘要

The present invention relates to a process for recovering energy and chemicals from a fuel comprising a part or parts of: hydrogen, hydrocarbon and hydrogen compounds by combustion/thermal decomposition during partial and/or total oxidation, in at least one reaction chamber during at least one reaction progress above atmospheric pressure after which produced gas, superheated or during partial or total moisture saturation, with the content of chemical and/or physical energy to be cleaned during the condensation of vaporized agents and compounds during the expansion cooling by at least one expansion turbine step of at least one partial step when from the fuel oxidation progress originating gas carried sub-/microscopic and visual dust particles are wetted by condensation, which condensation preferably comprises steam when appropriate also by other condensable agents and compounds as volatilizable metals/heavy metals as well as volatilizable hydrocarbons, when said dust particles constitute condensation nuclei during the condensation, whereby the weight of said dust particles is increased whereupon said dust particles are transferred from the gas phase to the liquid phase, which phases are separated by at least one separation device, simultaneously when the gas phase contains chemical energy, said energy is utilized for production of chemicals and/or energy, while the physical energy during the expansion cooling is converted into power by an expander turbine connected generator, or used for driving a stationary machine/engine or a mobile machine/engine, while further chemicals are recovered as a phase of solid and/or molten material and/or said sub-/microscopic and visual dust particles and/or in aqueous form and/or in gaseous state.
