Abstract
A cost-effective and rapid method is used for the removal of volatile organic compounds (VOC) from gaseous emissions. This involves the use of a sandwich filter made of polymetaphenylene isophthalamide (Nomex) based nonwoven fabrics loaded with a thin layer of activated carbon. The optimum mass of activated carbon per unit area of the fabrics and fabric thickness are 2.89 (mg/cm2), and 4.8 mm, respectively. The air permeability of these filters is 0.5 cm3/cm2/s. The filters are incorporated in simple equipment provided with solid-state sensors to monitor the concentration levels of VOC before and after removal by the filters. Data transfer on 2G mobile phone networks performed using a General Packet Radio Service (GPRS) link and a Global System for Mobile Communications (GSM) network are used to provide internet access for mobile. Testing of the proposed filtration system design with the exhaust gases emitted from gasoline combustion engines reveals at least 95% removal efficiency of VOC within 10 min
