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： The present invention relates to a method for treating synthesis gas, from an indirect or direct gasifier; the method including steps for: allowing the gas within a predetermined entry temperature range to flow into a first heat exchanger, allowing the gas to flow through the first heat exchanger while exchanging heat to a first medium, allowing the gas to transfer from the first heat exchanger to a subsequent last heat exchanger, allowing the gas to flow though the last heat exchanger while exchanging heat to a last medium, and allowing the gas to exit the last heat exchanger for being available to a further treatment, such as a cleaning treatment, within a predetermined exit temperature range, preferably below an ash or mineral solidification point. Furthermore, the present invention relates to a cooling system for cooling of synthesis gas and to a gasification system.

摘要： Methods are provided to prepare a low sulfur fuel from hydrocarbon sources, such as light tight oil and high sulfur fuel oil, often less desired by conventional refiners, who split crude into a wide range of differing products and may prefer presence of wide ranges (C3 or C5 to C20 or higher) of hydrocarbons. These fuels can be produced by separating feeds into untreated and treated streams, and then recombining them. Such fuels can also be formulated by combinations of light, middle and heavy range constituents in a selected manner as claimed. Not only low in sulfur, the fuels of this invention are also low in nitrogen and essentially metals free. Fuel use applications include on-board large marine transport vessels but also on-shore for large land based combustion gas turbines, boilers, fired heaters and transport vehicles and trains.

摘要： A method may include, but is not limited to: providing a volume of feedstock and a volume of oxygen-enriched air to a thermal reformer; reacting the volume of feedstock and the volume of oxygen-enriched air with the thermal reformer at an operating temperature to produce a raw syngas stream; removing particulate matter from the raw syngas stream with a two-stage cyclone assembly, wherein the two-stage cyclone assembly comprises a first cyclone and a second cyclone; scrubbing the raw syngas stream received from the two-stage cyclone assembly with a quench scrubber to produce an engine gas stream; and providing the engine gas stream to a CHP genset to be used as fuel.

摘要： A gasification system and a method for gasifying a particulate carbonaceous fuel are disclosed. The gasification system has a gasification chamber with an upper section and a lower section with a fuel inlet for injecting a particulate carbonaceous fuel and oxidant into the upper section whereby, in a thermo-chemical reaction, synthesis gas and residual char is generated. The gasification system further includes a separator configured to receive the synthesis gas and to separate residual tar form the synthesis gas. Further, there is a char bed disposed in the lower section formed by residual char generated in the thermo-chemical reaction and a gas-inlet at a bottom portion of the lower section for injecting gas into the char bed. The residual tar is injected into the char bed whereby, in a thermal cracking process, the residual tar is converted into synthesis gas. Hereby, it is possible to utilize the otherwise lost energy contained in the residual tar, and thereby achieve better efficiency in a gasification system, in a cost-effective and simple manner.

摘要： A system and process is provided for generating power from a syngas fermentation process. The process includes contacting hot syngas having a temperature above about 1400° F. with cooled syngas to produce a pre-cooled syngas having a temperature of 1400° F. or less at an inlet of a waste heat boiler. A waste heat boiler receives the pre-cooled syngas and is effective for producing waste heat boiler high pressure steam and a cooled syngas.

摘要： Systems and methods are provided for integrating a fluidized coking process, optionally a coke gasification process, and processes for production of additional liquid products from the coking and/or gasification process. In some aspects, the integrated processes can allow for conversion of olefins generated during a fluidized coking process to form additional liquid products. Additionally or alternately, in some aspects the integrated processes can allow for separation of syngas from the flue gas/fuel gas generated by a gasifier integrated with a fluidized coking process. This syngas can then be used to form methanol, which can then be converted in a methanol conversion process to form heavier products. In such aspects, olefins generated during the fluidized coking process can be added to the methanol conversion process to improve the yield. Additionally, in various aspects, the off-gas from the integrated conversion process can be used as an additional paraffin feed that can be recycled to one of the heat integration conduits in the fluidized coker for additional generation of olefins. This can provide a further increase in liquid yields using a carbon source (C4− paraffins) that is conventionally viewed as a low value product from coking.

摘要： Method of combining industrial processes having inherent carbon capture and conversion capabilities offering maximum flexibility, efficiency, and economics while enabling environmentally and sustainably sound practices. Maximum chemical energy is retained throughout feedstock processing. A hybrid thermochemical cycle couples staged reforming with hydrogen production and chlorination. Hydrogen generated is used to upgrade feedstocks including bitumen, shale, coal, and biomass. Residues of upgrading are chlorinated, metals of interest are removed, and the remainder is reacted with ammonia solution and carbon dioxide to form carbonate minerals. The combination provides emissions free production of synthetic crude oil and derivatives, as well as various metals and fertilizers. Sand and carbonate minerals are potentially the only waste streams. Through this novel processing, major carbon dioxide reduction is afforded by minimizing direct oxidation. Supplemental heat to run the reactions is obtained through external means such as concentrated solar, geothermal, or nuclear.
