PROCESS AND DEVICE FOR GASIFYING COAL

PROCESS AND DEVICE FOR GASIFYING COAL Part of the synthesis gas produced by coal gasification in an allothermiclly heated fluidized bed reactor is burned after removal of dust and sulfur and serves as a source of energy to heat the reactor by indirect heat exchange and to produce the steam required for the gasification process. The flue gas exiting from the heat exchanger of the reactor can be used to perform work in expansion turbines. The rest of the synthesis gas is available for use in downstream processes, such as iron ore reduction, or can be burned and used to perform work in turbines to produce electric current. The result is a process that is environmentally safer and operates with a better yield than direct coal burning or autothermal coal gasification, but requires no outside source of energy, such as nucler powr, as prior art allothermal coal gasification processes do.

Coal gasification and desulfurization

Electrical power generation

A method for combined cycle electrical power generation comprises utilising a coal hydrogenator 2 and a reactor 1 for producing from a methane-rich gas a hot crude hydrogen-containing gas which is fed directly (apart from an optional quenching stage) to the coal hydrogenator. The coal hydrogenator produces gaseous and liquid products which are combusted to drive a gas turbine 5 which drives an electrical generator 6. The hydrogenator also produces char which is combusted in a boiler 10 to form steam to drive a steam turbine 11 which, in turn, drives another electrical generator 12. Such direct use of the hot crude gas avoids having to pre-heat hydrogen-containing feed to the hydrogenator.

Conversion of waste carbon dioxide gas to bulk liquid fuels suitable for automobiles

Carbon dioxide gas exhausted from power stations is collected by means of absorption into an absorptive fluid. The carbon dioxide is used as the carbon skeleton for hydrocarbon oralcohol fuel. In another section, water is separated into its constituent elements, namely hydrogen and oxygen, by electrolysis. The hydrogen is combined with the carbon dioxide in an exothermic reaction to produce methanol. Methanol is a preferred automobile fuel as the pure substance or as a mixture with conventional motor fuel. If it is desired, the methanol may be converted to ethanol or conventional motor fuel. The process represents an energy conversion technology, since the carbon dioxide has no reductive (calorific) heat value, and is essentially inert.

HYBRID PROCESS USING A MEMBRANE TO ENRICH FLUE GAS CO2 WITH A SOLVENT-BASED POST-COMBUSTION CO2 CAPTURE SYSTEM

A process for recovery of COfrom a post-combustion gas includes pre-concentrating a COcomponent of the post-combustion flue gas by passing the post-combustion gas through a CO-selective membrane module to provide a CO-enriched permeate stream and a CO-lean reject stream. Next, in a COabsorber, both the CO-enriched permeate stream and COlean reject stream, fed to separate feed locations on the COabsorber, are contacted with a scrubbing solvent to absorb COand provide a carbon-rich scrubbing solvent.

Method and device for electrical energy generation (alternatives)

FIELD: electrical energy generation. SUBSTANCE: proposed method for electrical energy generation implies use of fuel suited to boilers such as cheap coal, heavy oil, or plastic wastes, as well as in some cases use of fuel suited to gas turbines. Fuel suited to boilers is first separated in proposed device into distillate and residue by partial recovery. Mentioned distillate is supplied (in some cases together with fuel suited to gas turbines) to gas turbine and burned to generate electrical energy. Then turbine exhaust gas produced due to fuel combustion is fed to boiler. After that residue is burned (in some cases together with fuel suited to boilers) to produce steam. This steam is also used for electrical energy generation. In this way electrical energy can be generated by using cheap low-grade fuel not suited to gas turbines by burning it in boilers thereby raising effectiveness of this fuel.

Methods for generating electricity from carbonaceous material with substantially no carbon dioxide emissions

Disclosed herein is a method for generating “clean” electricity from carbonaceous material, and producing high-pressure CO 2 which can be easily sequestered or utilized for a beneficial purpose, such as fuel production. This method utilizes a reformation process that reforms carbonaceous fuel with superheated steam into a high-pressure gaseous mixture that is rich in carbon dioxide and hydrogen gas. This high-pressure gas exchanges excess heat with the incoming steam from a boiler. Once cooled, the high-pressure gas goes through a CO 2 separator, after which the CO 2 -rich gas is sequestered underground or beneficially re-used. The remaining hydrogen-rich gas is used to generate power in a power generation subsystem, such as a gas turbine or a fuel cell. Therefore, carbon-free power is produced from coal, biomass, natural gas, or another carbon-based feedstock.

Two-stage coal gasification and desulfurization apparatus

The present invention is directed to a system which effectively integrates a two-stage, fixed-bed coal gasification arrangement with hot fuel gas desulfurization of a first stream of fuel gas from a lower stage of the two-stage gasifier and the removal of sulfur from the sulfur sorbent regeneration gas utilized in the fuel-gas desulfurization process by burning a second stream of fuel gas from the upper stage of the gasifier in a combustion device in the presence of calcium-containing material. The second stream of fuel gas is taken from above the fixed bed in the coal gasifier and is laden with ammonia, tar and sulfur values. This second stream of fuel gas is burned in the presence of excess air to provide heat energy sufficient to effect a calcium-sulfur compound forming reaction between the calcium-containing material and sulfur values carried by the regeneration gas and the second stream of fuel gas. Any ammonia values present in the fuel gas are decomposed during the combustion of the fuel gas in the combustion chamber. The substantially sulfur-free products of combustion may then be combined with the desulfurized fuel gas for providing a combustible fluid utilized for driving a prime mover.

Combined cycle power plant with integrated CFB devolatilizer and CFB boiler

A high efficiency economical coal fired combined cycle power generation system and process is described. The system utilizes a circulating fluid bed ("CFB") coal devolatilizer which is fluidized with recycled coal volatiles. The devolatilizer is heated indirectly with hot bed material from a conventional CFB boiler burning the devolatilized coal (char). The CFB boiler is fluidized by gas turbine exhaust gas. The ratio of high efficiency/low capital cost Brayton cycle (gas turbine) power output to lower efficiency, higher capital cost Rankine cycle (steam turbine) power output is maximized by concurrently and/or successively preheating the gas turbine compressor discharge with; (1) gas turbine exhaust (recuperator), (2) hot coal volatiles exiting the devolatilizer, (3) coal char CFB boiler hot bed material (with either an external or internal heat exchanger), and (4) CFB boiler flue gas. The process and method described produces a thermally cracked, clean product gas with a high Btu content (˜500 BTU/SCF) and is, therefore, readily usable in gas turbines which are designed for natural gas without design modification. This high Btu product gas also reduces fuel gas cleaning volume and fuel gas sensible heat loss. The product gas yield and/or the devolatization reaction temperature is increased by either partially substantially or supplementing the fluidizing gas with steam and/or air or oxygen.

Control system for a gas-turbine installation

A gas-turbine electricity-generating installation has a pressurized-air fuel (coal) gasifier for producing a highpressure combustible gas which drives a high-pressure turbocompressor, the low-pressure combustible gases emerging from this turbocompressor being delivered to a boiler for driving a steam-generating circuit.

The control system comprises a regulating valve between the gasifier and the gasinlet to the turbine of the high-pressure turbocompressor which is responsive to the output pressure at the gasifier to maintain the same substantially constant.
