摘要:
Using a method and installation for separating acid components, dust and tar from hot gases of gasification installations, an economical method using a corresponding installation is to be created, which enables acid compounds HF, HCl, H2S, dust and tar to be reliably separated in the highest possible temperature range. The aim is achieved in that the media flow leaving the gasification at above 700° C. is fed with additives to a desulfurization process and subsequently to a combined cyclone 9 having associated filter cartridges 17 in a common vessel 8, and the gas is withdrawn for further use downstream of the filter cartridges.
摘要:
A method for producing synthesis gas by gasifying a biomass in a fluidized bed is disclosed wherein the biomass is fed to a fluidized bed gasifier. In order to eliminate vapor-forming alkalis produced during the gasification, the method brings the synthesis gas into contact with getter ceramics.

In the case of a device for gasification of carbonaceous fuels, having a discharge for slags into a slag bath, a solution is supposed to be created with which the gasifier discharge opening is reliably kept at a temperature that guarantees that the slag will flow out. This is achieved in that the gasifier discharge opening (6) is equipped with a ceramic drip edge (7) that can be electrically heated.

With a method for the gasification of a biomass in a fluidized bed, wherein the biomass is first pre-dried and passed to the fluidized bed gasifier, subsequently the raw gas from the gasifier impacts a recirculation cyclone and subsequently at least one raw gas cooler, the yield of such a method of procedure is supposed to be improved and the system costs are supposed to be lowered.This is achieved in that the dusts that occur in the hot gas filter that follows the raw gas cooler are recirculated into the introduction system of the biomass.

A synthesis gas (H2+CO) that comes from a gasifier is supposed to be used in more efficient and optimal manner, particularly for generating electricity, whereby then, CO2 that occurs at the same time is supposed to be passed to storage. This is achieved in that—the synthesis gas (H2+CO) and oxygen (O2) from an air separation system are combusted in a burner, and relaxed by way of a gas turbine (driving a generator), —CO2 is separated in the waste gas stream and passed to a compressor driven by the gas turbine, and—passed to CO2 storage as compressed CO2.

With a method and a system for treatment of a hot crude gas generated by an entrained flow gasification system, removal of the compounds that contain sulfur and carbon is supposed to be undertaken in such a manner that hot gas is made available for further use. This is achieved in that a desulfurization (7) follows the gasifier (2), in series, in the flow path of the hot gas, followed by a solid separation (8, 9), whereby behind the solid separation (8, 9), a partial stream (13) of the gas is provided downstream by way of a water quench (14), a Venturi scrubber (15), a crude gas cooler (16), as well as an H2O separation (17) and a compressor (18), the flow path (19) of which is passed back, cooled, into the circuit, behind the gasification (2) and ahead of the desulfurization system.

摘要:
A process for the production, treatment and combustion of synthesis gas for the purpose of generating electric power is disclosed. The synthesis gas is produced from a solid, carbon-containing fuel with the aid of an oxygen-containing gas and treated by a slag-separating device and a device separating alkalis. Subsequently, the synthesis gas produced is fed to an expansion turbine where the pressure energy is used for generating power. On account of the treatment and separation of alkalis the expansion turbine is protected from corrosion and mechanical impact. The expanded synthesis gas is then burnt under pressure and the combustion is used in a combined-cycle process using a gas turbine, steam generator and steam turbine for generating power. The process thus has an increased efficiency. Apparatus for use of the process is also described.
