EU’s climate policy is focused on the reduction of harmful emissions. The energy sector put a great emphasis on the reductionof emissions of sulfur oxides SOx, nitrogen oxides NOx, carbon monoxide CO, particulates and carbon dioxide CO₂ . Mitigation of CO₂ emissions is the challenge of the power sector, because just under 80% of the electricity generated in Poland is powered by coal-fired power plants. Technologies reducing greenhouse gas emissions, including technologies, CO₂ capture and storage (CCS – Carbon Capture and Sequestration), are becoming increasingly important, according to the introduction of CO₂ emissions trading system – EU ETS. The Carbon Capture and Storage (CCS) technology is one of the key ways to reconcile the rising demand for fossil fuels, with the need to reduce CO₂ emissions. Globally CCS is likely to be a necessity in order to meet the Union’s greenhouse gas reduction targets Post-combustion process like amine based chemical absorption CO₂ is ideally suitable for conventional power plants. There are still only a few facilities worldwide in which this technology is actively being practiced and the demonstration phase of CCS technology needs more activity – the biggest one in Europe have 280 t CO₂ /d yield and is located in Mongstad in Norway. This paper presents the progress of the CO₂ capture from the flue gas research implemented within the framework of the Strategic Research Programme “ Advanced technologies for energy generation: Development of a technology for highly efficient zero-emission coal-fired power unitswith integrated CO₂ capture”. Some of the experience of the researchers performing CO₂ capture plants on a laboratory, semi-technical and pilot scale are presented. First pilot tests of CO₂ capture from coal- fired flue gas in Poland were carried out in cooperation with TAURON Polska Energia and Tauron Wytwarzanie, at Laziska Power Plant for six months of 2013 year. The Pilot Plant was connected to the hard coal-fired boiler. The plant is able to receive about 200m3/h of real flue gas that contains different types of pollutants such as SOx, NOx and particles. The Pilot Plant consists of flue gas pre-treatment unit – deep desulfurization, and CO₂ capture unit – consist of absorber and desorber columns. The Pilot Plant operates 24 h per day, 5 days per week. Because the CO₂ concentration in flue gas to be treated consequently fluctuates round the clock operation allows for extended evaluation of the solvent, and capture process efficiency on real work parameters of the boiler. Over 500 h, 81 tests and more than 20 t of separated CO₂ were achieved during the operation with 30 wt% MEA (monoethanolamine). The unique design of the Pilot Plant allowed for the evaluation of various process modifications. Process modifications such as split stream and heat recuperation had been evaluated with the plant. The effect of heat recovery – recuperation can easily be seen in Fig.5. Achieved efficiency of CO₂ separation was above 85% and the lowest noticed energy demand of sorbent regeneration was 3,6 MJ/kg CO₂ – for MEA as a sorbent, and heat recuperation evaluated – Fig. 3. Those power required for regeneration comprise the energy requirements of the process subsequently determining the operating and maintenance costs – about 50–60% of OPEX. The main noticed operational problem of the CO₂ capture plants was corrosion of the some devices, that means how important is the right material choosing during plant designing stage.
