    摘要： Disclosed is a method for operating an IGCC power plant, wherein the coal gas from a gasifier, comprising CO and hydrogen, is supplied to at least one shift stage, wherein this is converted primarily into CO2 and hydrogen and the coal gas is subjected to at least one gas cleaning step. The coal gas is conducted over a membrane, which at least partially selectively separates the hydrogen from the coal gas. In order to achieve driving potential in the membrane, a flushing gas is used on the permeate side. The hydrogen depleted retentate is fed to a CO2 conditioning process, while the separated hydrogen is fed together with the flushing gas to a gas turbine as fuel gas. The flushing gas used for the membrane is a component of the waste gas produced in the gas turbine after the waste gas has left the waste heat recovery boiler, which is connected downstream of the gas turbine. In the power plant, the gas turbine also functions as a means for providing the flushing gas. The power plant comprises a line from the waste heat recovery boiler connected downstream of the gas turbine to the permeate side of the membrane.

    摘要： Provided is a power plant for generating electrical energy comprising a combustion chamber for producing steam, at least one downstream flue gas purification stage, a separation stage for CO2, a recycling circuit for the flue gas, and a high-temperature O2 membrane, which is connected upstream of the combustion chamber. The high-temperature O2 membrane has an inlet and an outlet on the feed side which are thermally coupled by way of a heat exchanger. On the permeate side, the high-temperature O2 membrane has only an outlet which is connected to the combustion chamber and/or the flue gas recycling circuit and a means for cooling and/or compression which is disposed in this outlet. The power plant, in which coal is burned using substantially pure oxygen, and in which the combustion waste gas is purified and partially recirculated to the combustion process, is operated in such a way that the oxygen that is used is obtained by separation from air using a high-temperature O2 membrane, wherein the membrane is operated with atmospheric air at a pressure of up to 2 bar on the feed side and a negative pressure of between 0.02 and 0.5 bar is applied on the permeate side.

    摘要： Until now, additional components such as afterburners, reformers or heat exchangers are arranged as separate units and, as a rule, are connected to the high-temperature fuel cell stack by means of pipes. The disadvantage of this construction method is that it requires a large constructional volume and high investment costs to install said components. The invention relates to a high-temperature fuel cell system that is modularly built, wherein the additional components are advantageously and directly arranged in the high-temperature fuel cell stack. The geometry of the components is matched to the stack. Additional pipeworking is thereby no longer necessary, the style of construction method is very compact and the direct connection of the components to the stack additionally leads to more efficient use of heat.

    摘要： A method for separating carbon dioxide from a flue gas using a membrane (membrane module) is characterized in that the flue gas is at temperatures above the condensation point of the water vapor before entering the membrane separation stage. In this way, condensation of any potentially entrained water vapor out of the flue gas is avoided, so as to consistently prevent clogging of the membrane pores. The high temperatures can be achieved in different ways. The temperature of the flue gas can easily be increased to the necessary temperatures by way of an upstream heat exchanger or a burner. A compressor, which is connected upstream of the membrane module and also advantageously increases the CO2 partial pressure, brings about the necessary temperature increase at the same time. As a further alternative for the invention, the CO2 separation is performed even before desulfurizing the flue gas. This notably has the advantage of the flue gas in this process stage still being at temperatures above the condensation point of the water vapor, and thus not having to be heated separately, in addition to which, it generally carries little water vapor at this stage of the scrubbing operation.

    摘要翻译： 使用膜（膜组件）从烟道气中分离二氧化碳的方法的特征在于，在进入膜分离阶段之前，烟道气处于高于水蒸汽冷凝点的温度。 以这种方式，避免任何潜在夹带的水蒸气从烟道气中冷凝，从而始终防止膜孔堵塞。 高温可以通过不同的方式实现。 烟气的温度可以通过上游热交换器或燃烧器容易地增加到必要的温度。 连接在膜组件上游的压缩机也有利地增加CO 2分压，同时带来必要的温度升高。 作为本发明的另一替代方案，即使在烟道气脱硫之前也进行CO 2分离。 这显着地具有在该工艺阶段中的烟道气仍然处于高于水蒸气冷凝点的温度的优点，因此不必单独加热，除此之外，其通常在该阶段几乎没有水蒸汽 擦洗操作。
