Advanced CO2 Capture Pilot Plant at Tauron's coal-fired Power Plant: Initial Results and Further Opportunities

AbstractInstitute for Chemical Processing of Coal in cooperation with industrial partners: TAURON Polska Energia S.A. and TAURON Wytwarzanie S.A. designed, constructed and operated pilot plant at Łaziska Power Plant in Łaziska Górne, Poland.The carbon capture facility is based on amine post-combustion process technology and used 30 wt% aqueous ethanolamine solvent. Approximately 1000 kilograms of CO2 can be captured per day from flue gas stream of 200 m3/h of a 225MWe hard coal fired boiler. The plant captured its first tonne of CO2 in August 2013. The purpose of this study is to present initial results from tests carried out at Łaziska Power Plant using different process flow sheets: heat-integrated stripping column and split flow process.The tests provide valuable experimental evidence for modifications described in the literature, mainly through modelling and demonstrate that flow sheet modifications, despite the increase in plant complexity, are worth to consider

Nitrosamines and nitramines in Carbon Capture plants

The use of amine absorption in carbon capture technologies is related with the formation toxic and potentially carcinogenic amine degradation products such as nitrosamines and nitramines. These substances can be created within both the solvent and the atmosphere when air components (mainly NOx) and amines react with each other. These substances may pose environmental and health risks depending on the level and duration of the exposure. In this paper, formation and occurrence of nitrosamines and nitramines in carbon capture plants were described. Emission reducing technologies have been also mentioned. Furthermore, an overview of experimental data of emission of nitrosamines and other major degradation products has been pointed out
