The topic of CO2 removal from flue gas by amine absorption is of interest to science and industry. Especially recently, studies are conducted not only on a laboratory scale, but also on a pilot scale. The aim of the research is to increase the efficiency of CO2 removal process and decrease the energy required for sorbent regeneration. For this purpose, new sorbents and modifications to existing systems are being introduced. This work presents selected technological modifications, which affect the improvement of process efficiency and energy consumption ratio, as well as presents results of research on the impact of internal heat exchange in desorption column on CO2 capture process. The studies were conducted on Pilot Installation in Łaziska Power Station – TAURON Wytwarzanie SA

Please cite as: CHEMIK 2013, 67, 5, 407?414 Introduction According to Article 10 sec. 1 of the amended Directive EU ETS 2009/29/EC, in the third settlement period (2013÷2020) of the greenhouse gas emission allowance trading scheme, auctioning shall be the basic method of allocating emission allowances [1]. An exception to this rule are the energy-intensive industries (exposed to the so-called carbon leakage), other industries (pursuant to the principle of gradual derogation from free allocation of allowances), as well as power generation industry in certain Member States subject to derogation, i.e. Bulgaria, Cyprus, Czech Republic, Estonia, Hungary, Lithuania, Romania and Poland. In return, those industries shall be obligated to invest in industry modernisation equal to the value of allocated free allowances. This means that as of 1 January 2013 the national power sector, forced to incur environmental costs related to CO2 emissions,...

Impact of the composition of absorption blend on the efficiency of CO2 removal

Andrzej WILK, Lucyna WIĘCŁAW-SOLNY, Aleksander KRÓTKI, Dariusz ŚPIEWAK ? Centre for Process Research, Institute for Chemical Processing of Coal (IChPW), Zabrze, Poland Please cite as: CHEMIK 2013, 67, 5, 399?406 Introduction The amine absorption processes are widely used in the industry to purify refinery gases, process gases or natural gas. Recently, amine absorption has also been considered for application in CO2 capture from exhaust fumes created as by-product of electric power generation from fossil fuels. Amine absorption is based on a reversible reaction between weak bases, e.g. ethanolamine, and acidic gases, including i.a. carbon dioxide. CO2-containing gas (e.g. exhaust fumes) is fed into the absorption column, where it comes in counter flow contact with unsaturated sorption solution. Carbon dioxide is absorbed by the solution, while the gas leaving the column is purified. The solution with absorbed CO2 is pre-heated with a solution regenerated in the heat exchanger, and then directed to the regenerator. In the regenerator, in the supplied heat, the amine-CO2 compound...
