What is Absorption

Due to more stringent emission regulations, very efficient emission control technologies are required adopting National IPPC Permits based on BAT Conclusions. Some abatement techniques are operating inside IPPC plants based in Italy. This paper include the results of a screening of Italian IPPC Plants up to day, trying to highlight operating conditions of abatement devices and possible already existing improvements for several compounds removal. The abatement techniques analyzed operate mainly on VOC content reduction or on inorganic compounds abatement. ISPRA experience has allowed to analyze different operative conditions, related with abatement techniques and their application in IPPC permitted plants. The results of this analysis allow to suggest a possible reconsideration and new assessment for some end-of-pipe devices, in order to find other better defined operational contexts, different from actually Italian provisions and an evaluation of current operational performances of the devices, in order to improve their environmental conditions, consistently with BAT application.
