There have been many attempts at solving this problem, but with limited success. This paper proposes a wireless gas leak detection and localization solution. With a monitoring network of 20 wireless devices covering 200m2 , 60 propane releases are performed. The detection and localization algorithms proposed here are applied to the collected concentration data, and the methodology is evaluated. A detection rate of 91% is achieved, with seven false alarms recorded over three days, and an average detection delay of 108 seconds. The localization results show an accuracy of 5 meters. Recommendations for future explosive gas sensor design are then presented.  \nI. INTRODUCTION  \nThe number of gas leaks that occur every year on industrial plants is unknown. Most of these leaks, even if detected, go unreported when they don’t directly lead to tangible accidents. Environmental Protection Agency (EPA) reports estimate that, in the United States alone, these plants emit close to one billion cubic meters of methane (not taking any other gas into consideration) . Most of these losses (around 80%) seem to come from leaky compressors, valves, seals and connectors [1] . In 2012, approximately 2,200 million metric tons of CO2 equivalent were accidentally released from petroleum systems and other chemical processes necessary for the production of plastics, cement, iron and steel [2] . It is estimated that around 800,000 to 900,000 leaks are investigated each year on refineries, with between 200 and 300 of them having directly resulted in loss of life, injuries, damaged equipment, or operational losses [3] . In short, industrial gas leaks present a major challenge in the quest for safe, environmentally-friendly, and cost-effective plants.  \nIn this paper, we present a distributed wireless sensor approach to the problem of gas leaks in large industrial spaces (chemical plants, refineries, oil rigs, etc.) . The objective is to detect and localize “refinery-like” gas leaks within seconds of their occurrence. With many corporations upgrading their facilities with a low-power wireless infrastructure (WirelessHART) [4], a leak detection system that simply connects to the wireless umbrella would be a desired addition to the existing safety framework. Our goal is to study the feasibility  \nF. Chraim and K.

In section II we will review some of the available solutions to the problem at hand, both at the academic level and commercially. Our approach is then presented in section III, where we look at the system architecture, the hardware and the detection/localization algorithms. Our experimental results are shown in section IV, in which we validate our approach using real Propane leaks.
