摘要:
A system for producing high-quality gas includes a heat carrier hoist, a coke feeder, a heat carrier heating furnace, a gas mixer, a high-temperature induced draft fan, a heat carrier storage tank, a dryer, a hopper, a concentrating solar collection pyrolysis-gasification reactor having a double-tube structure, a three-phase separator and a coke collecting bin. The system may use an adjustable concentrating solar collection technology in combination with a heat carrier circulation heating process, so as to effectively solve heat requirements of the waste pyrolysis and gasification process, reduce the waste material consumption caused by energy supply, and improve the effective utilization of raw materials.
摘要:
This invention relates to a power recovery process in waste steam/CO2 reformers in which a waste stream can be made to release energy without having to burn the waste or the syngas. This invention in some embodiments does not make use of fuel cells as a component but makes use of exothermic chemical reactors using syngas to produce heat, such as Fischer-Tropsch synthesis. It also relates to control or elimination of the emissions of greenhouse gases in the power recovery process of this invention with the goal of producing energy in the future carbonless world economy.
摘要:
Energy-efficient gasification-based multi-generation apparatus, facilities, or systems, and methods of modifying existing gasification-based multi-generation apparatus and the various conventional thermal coupling arrangements, are provided. Apparatus for managing waste heat recovery through integration of a gasification-based multi-generation facility or other multi-generation system with a hydrocarbon refining facility or other hydrocarbon refining system and methods of providing the respective integration are also provided. An exemplary apparatus includes an integrated site energy management system configured according to one or more process-based thermal coupling schemes comprising one or more thermal coupling arrangements between a gasification-based multi-generation system or facility and a hydrocarbon refining system or facility. The gasification-based multi-generation system or facility can include an acid gas removal system or plant configured to remove acidic contaminants from a raw syngas feed to thereby provide a treated syngas feed, the acid gas removal system or plant containing a separation section including a solvent regenerator, and a gasification system configured to generate the raw syngas feed from a carbon-based feedstock. The hydrocarbon refining system or facility can include an aromatics system or plant containing a xylene products separation section including one or more of the following: an Extract column and a Raffinate column. The integrated site energy management system can include a hot-water system extending between the separation section of the acid gas removal system or plant and the xylene products separation section of the aromatics system or plant, and a plurality of added heat exchanger units providing various advanced thermal coupling arrangements.
摘要:
A solid gasification apparatus includes a reaction chamber thermally insulated by a heat insulating material, a heat beam fluid heat exchange apparatus that produces a first heated gas and a second heated gas, and a unit that includes a gas flow path. The unit spays the first heated gas against a material solid in a reaction chamber to heat the material solid, and, simultaneously, makes the material solid react with the first heated gas to produce a produced gas containing the element of the material solid. The unit makes a second heated gas contact and react with the produced gas.
