Following the mechanical assembly of the cells, the cells are filled with electrolyte and the cell chemistry is conditioned (formation and ageing). Among other things, this produces various gaseous and vaporous process emissions, which are to be fed into a targeted and suitably designed exhaust air after-treatment system in order to permanently comply with the emission limits required by the BImschG and TA Luft.<\/p>

A solid design basis and air volume balance was developed through comprehensive research and analysis of the scientific literature as well as the collection of available process and manufacturer information. PURIFICON GmbH supported the project for more than three years, enabling the design to be continuously refined and successfully commissioned.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

The naturally grown exhaust air system with a total of five integrated radial fans and around 30 extraction points did not deliver the desired extraction performance in some places. The reasons for this were not clear at first glance. The exhaust air temperature after the gas scrubber was still too high for it to enter the biofilter.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

Comprehensive spatially and temporally resolved measurements of the indoor air parameters temperature, humidity and flow allow a comprehensive understanding of the problem. Together with IR thermal imaging, they form the data basis for creating a digital twin. Flow simulations (CFD analysis with ANSYS Fluent) were then used to simulate the actual situation and subsequently test optimization measures.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

An \u00fcber 80 Absaugstellen mit Testst\u00e4nden, Zerlege- und Waschpl\u00e4tzen gelangten VOC-haltige Abluftstr\u00f6me in das Raumluftsystem. Nach Identifikation von potenziell krebserzeugenden Stoffen in den verdampfenden Treibstoffresten sollte die Absaugung signifikant verbessert werden. Aus Gr\u00fcnden des Umweltschutzes sollte ferner ein eigenes Abluftnachbehandlungssystem konzipiert werden, um die VOC-Emission in die Atmosph\u00e4re nach Stand der Technik zu minimieren.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

The evaluations of the measurements carried out and the derived parameters of separation efficiency and loadability showed that the activated carbon was only able to selectively remove part of the mixture of substances from the exhaust air flow. Specific suggestions for optimization with regard to contact time, bulk height, etc. help to optimize the adsorber and tailor it to the process.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
