摘要:
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 method for removing acid gases from a fluid flow using an absorbent including an aqueous solution with at least two different amines. An amine in a proportion of greater than 50 wt. % of the total amine amount in the aqueous solution is the first amine component in the aqueous solution, and a sterically hindered amine in a proportion of less than 50 wt. % is the second amine component in the aqueous solution. The fluid flow is brought into contact with the absorbent at a partial pressure of

摘要:
The invention relates to a desulfurization process, wherein a gas mixture is subjected to a separation process to separate the acidic components of the gas, an acid gas containing carbon dioxide and sulfur compounds, in particular hydrogen sulfide, being formed in this process, the acid gas being sent to a Claus plant for separation of elemental sulfur, and the residual gas leaving the Claus plant being subjected to a further separation, in which the water formed in the Claus process is at least partially removed, only technically pure oxygen being supplied as the oxygen-containing reaction gas to the Claus plant, and carbon dioxide in a purity which allows direct sequestration or industrial utilization being removed downstream from the Claus plant.

The present invention discloses a microreactor for performing heterogeneous catalytic reactions, being of plate or stack construction for industrial use, with provision made for chambers between the plates for the chemical reaction and for the heat removal. Inside the reaction chambers, catalyst material is applied to the internal walls or filled into recesses, and in all chambers there are spacers. In particular the slot-shaped reaction chambers have channels with a hydraulic diameter smaller than 1500 μm and a ratio of free slot width to free slot height in the range of 10 to 450.
摘要:
A method for feeding back exhaust gas from a gas turbine with a downstream waste heat boiler, wherein this exhaust gas is metered into the air inflow stream of a gas turbine, with the result that the temperature and the composition of the exhaust gas can be controlled, and in this way highly concentrated carbon dioxide (CO2) is obtained which can be injected into a storage facility, so that the balance of the carbon dioxide for the entire process can be kept low or is negligible. The temperature in the gas turbine can be lowered and the proportion of carbon dioxide in the exhaust gas can be considerably increased. After combustion has taken place and heat has been exchanged, gas washing is possible, carbon dioxide can be recovered and, the proportion of free oxygen in the exhaust gas can be lowered.
