“…The selectivity of membranes for gas separation depends primarily on the properties of the material from which they are made; the higher the values of both parameters for the separated components, the better the separation process. Usually, however, with increasing selectivity, permeability decreases, and vice versa [28,29]. Among different types of membranes, currently, the most commonly used are polymeric membranes, which are characterized by a selectivity of not more than 100.…”

“…Most of the carbon capture technologies are known at present, but they are used on a limited scale (mainly in the chemical, petrochemical and food processing industries), and these carbon capture technologies are not presently sufficient for application in full-scale power plants [7]. A vast number of post-combustion technologies for carbon dioxide removal exist in industry: physical and chemical absorption, adsorption, membrane processes, cryogenic and electrochemical processes [1].…”

With regard to the climate policy that has been adopted, the implementation of the carbon capture and storage and carbon capture and utilization technologies seems to be the unavoidable solution to reduce emissions from the energy sector. As most Polish energy is derived from coal, the government has taken steps to reduce CO 2 emissions by initiating a strategic research program-"Advanced technologies for energy generation: Development of a technology for highly efficient zero-emission coal-fired power units integrated with CO 2 capture." This paper presents the results of an investigation of a process for continuous removal of CO 2 from the gas stream on a laboratory unit. This study was conducted at the Institute for Chemical Processing of Coal in Zabrze, Poland. The purpose of the tests that were conducted was to establish the effect of the sorption column load on CO 2 recovery and on the process regeneration heat duty. In the second part of the paper, a simple comparison of three amine solvents is presented as a part of the solvent selection process for further pilot plant tests.

“…Their separation is the primary task of a carbon dioxide capture (CC) unit used in post-combustion technologies. Separation involves chemical absorption (mainly 30 percent solution of MEA or MDEA) Piptone and Bolland, 2009;Skorek-Osikowska et al, 2012b) and membrane separation with relatively cheap membranes (Janusz-Szymańska and Kotowicz and Janusz-Szymańska, 2011) for CO 2 capture. The main advantage of these technologies is simple integration of CC unit with currently exploited power plants.…”

In this paper an air separation unit was analyzed. The unit consisted of: an ionic transport membrane contained in a four-end type module, an air compressor, an expander fed by gas that remains after oxygen separation and heat exchangers which heat the air and recirculated flue gas to the membrane operating temperature (850 °C). The air separation unit works in a power plant with electrical power equal to 600 MW. This power plant additionally consists of: an oxy-type pulverized-fuel boiler, a steam turbine unit and a carbon dioxide capture unit. Life steam parameters are 30 MPa/650 °C and reheated steam parameters are 6 MPa/670 °C. The listed units were analyzed. For constant electrical power of the power plant technical parameters of the air separation unit for two oxygen recovery rate (65% and 95%) were determined. One of such parameters is ionic membrane surface area. In this paper the formulated equation is presented. The remaining technical parameters of the air separation unit are, among others: heat exchange surface area, power of the air compressor, power of the expander and auxiliary power. Using the listed quantities, the economic parameters, such as costs of air separation unit and of individual components were determined. These quantities allowed to determine investment costs of construction of the air separation unit. In addition, they were compared with investment costs for the entire oxy-type power plant.
