Abstract


Oil and Gas  is one of the most basic and most important sources of energy for us but of the most basic disadvantage of petroleum products usage is the releases of lots of gases and unwanted substances in air when it is burned and used . Lot of carbon and unburned hydrocarbon releases in air when we use petroleum products like diesel, gasoline or liquid petroleum gas.  if pollution level increases. VOC’S (Volatile organic compounds) is one them and it has harmful effect for human health and environment. By definition of world environmental agencies VOC’S is any compound of carbon, excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates, and ammonium carbonate, which participates in atmospheric photochemical reactions, except those designated by EPA as having negligible photochemical reactivityKeeping the above discussion in mind we have found that there is a strong need of a technology that should be easy to use, less costly and fast, for monitoring the level of VOC’S in ambient air and petroleum industry or a petrochemical plant for fugitive emissions and point source emissions. I have chosen a simple electronic sensor that responds to change in concentration in VOC’S in contact air, I have interfaced it with microcontroller, programmed it and displayed the concentration of gas on digital display, thus developing a simple instrument for current state VOC’S level at any place.
