    • 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.
    • 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。

    • Disclosed is a method for producing semi-finished products from a shape memory alloy, particularly an NiTi shape memory alloy, wherein a powder is first produced from a shape memory alloy, and subsequently the powder is divided into a coarse fraction and a fine fraction in a separating cut T. While the fine fraction is required, in particular, for the production of a first semi-finished product, employing the metal injection molding (MIM) method, the coarse fraction can be used for the production of a second semi-finished product, employing the hot isostatic pressing (HIP) method. The advantages of the invention can be summarized as follows. The MIM method for producing semi-finished products from a shape memory alloy is qualitatively improved and more cost-effective to implement if the coarse fraction that is typically obtained during powder production, but not used for the MIM process, can advantageously be supplied to a further process, in this case the HIP process. Due to the use of particularly fine powder, the semi-finished products produced by way of the MIM method have an advantageous, powder-metallurgical microstructure. In particular, the alloying elements are distributed particularly homogeneously in these semi-finished products, casting flaws or segregations do not usually occur, no anisotropy of the structure occurs as a result of the processing steps, and ternary alloys can be processed, which due to the mechanical properties thereof, cannot be processed by way of conventional forming methods.

    • The invention relates to a method for producing highly porous, metallic molded bodies. The inventive method consists of the following steps: a metallic powder used as a starting material is mixed with a dummy; a green body is pressed out of the mixture; the green body is subjected to conventional mechanical machining, the dummy advantageously increasing the stability of the green body; the dummy material is thermally separated from the green body by means of air, a vacuum or an inert gas; and the green body is sintered to form the molded body and is then advantageously finished. Suitable materials for the dummy are, for example, ammonium bicarbonate or carbamide. The mechanical machining carried out before the sintering advantageously enables a simple production close to the desired final contours, even for complicated geometries of the molded body to be produced, without impairing the porosity, and without high wear of the tools. The workpiece is advantageously sufficiently stable in terms of pressure for the green machining as the dummy material is still present in the pores of the green body during the machining.
