Feasibility of polymer membranes for carbon dioxide recovery from flue gases

Abstract The feasibility of polymer membranes for the recovery of CO 2 from flue gases of a power plant is examined. With a computer program based on the cross flow permeation model for membranes, several parameters are optimized to obtain the lowest specific CO 2 mitigation costs. With gas separation membranes commercially available, the minimum attainable specific mitigation costs are calculated to be US

Carbon dioxide recovery from industrial processes

48 per tonne of CO 2 avoided (at 50% CO 2 purity, 75% CO 2 recovery). When restrictions are posed to the purity of CO 2 (95%) and the degree of CO 2 recovery (90%), this figure is much higher: US

Underground storage of carbon dioxide

71 per tonne of CO 2 avoided. Cost reduction possibilities and perspectives are discussed. Our analyses shows that membranes with a selectivity of at least 200 are required to make membranes a serious competitor of other separation techniques.

Carbon dioxide recovery using a dual gas turbine IGCC plant

The ongoing human-induced emission of carbon dioxide (CO2) threatens to change the earths climate. One possible way of decreasing CO2 emissions is to apply CO2 removal, which involves recovering of carbon dioxide from energy conversion processes and storing it outside the atmosphere. Since the 1980s, the possibilities for recovering CO2 from thermal power plants received increasing attention.In this study possible techniques of recovering CO2 from large-scale industrial processes are assessed.In some industrial processes, e.g. ammonia production, CO2 is recovered from the process streams to prevent it from interfering with the production process. The CO2 thus recovered can easily be dehydrated and compressed, at low cost. In the iron and steel industry, carbon dioxide can be recovered from blast furnace gas. In the petrochemical industry CO2 can be recovered from flue gases, using low-temperature heat for the separation process.Carbon dioxide can be recovered from large-scale industrial processes and in some cases the cost of recovery is significantly less than CO2 recovery from thermal power plants. Therefore this option should be studied further and should be considered if carbon dioxide removal is introduced on a wide scale.

Regulation for combined heat and power in the European union

To prevent recovered carbon dioxide from entering the atmosphere, it must be disposed of or stored. In this chapter the global potential for storing carbon dioxide underground is discussed together with the associated costs. Special attention is given to the injection of carbon dioxide into former hydrocarbon reservoirs and in aquifers.

Carbon dioxide recovery from flue gases of a conventional coal-fired power plant by low-temperature distillation

A new scheme is described for electricity production based on coal gasificiation with recovery of CO2. Coal is gasified into a synthesis gas, mainly consisting of hydrogen and carbon monoxide. After clean-up, this synthesis gas is separated by a membrane into a carbon-rich gas and a hydrogen-rich gas. The hydrogen-rich gas is fed to a conventional gas turbine. The carbon-rich gas is fed to another gas turbine, where it is fired in a mixture of oxygen and CO2. The exhaust of the latter is almost pure CO2 and can be stored outside the atmosphere. The CO2 emissions of this plant are about 10% of the emissions of an IGCC plant without CO2 recovery, and the conversion efficiency is approx. 6% lower. A first estimate is that the electricity production costs are about one third higher. It is found that the specific emission reduction costs can be limited to about

16 per tonne of CO2 avoided. The main technical problem of this new scheme is the development of a new type of gas turbine with CO2 as working fluid.

Simulation and optimization of carbon dioxide recovery from the flue gases of a coal-fired power plant using amines

Combined heat and power generation (CHP) is an important option for reducing the primary energy consumption. The share of CHP-related electricity production in the EU-12 decreased from 8% to 6% of the total produced electricity. Exceptions to this trend are Denmark and The Netherlands. The increase is mainly stimulated by the energy companies, which invest in CHP for their own risk. Additionally, in Denmark also a number of standard settings are used, especially for district heating.

Carbon dioxide recovery from an integrated coal gasifier combined cycle plant using a shift reactor and a scrubber

To reduce the emissions of carbon dioxide to the atmosphere, carbon dioxide can be recovered from flue gases of power plants and stored. In this chapter, we examine the feasibility and costs of recovering carbon dioxide from the flue gases of a conventional coal-fired power plant using a low-temperature distillation method. This kind of plant is chosen because of the high concentration of carbon dioxide in the flue gases, which reduces the energy consumption per tonne of carbon dioxide recovered.
