To avoid such Received 5 December 2011 situations, a considerable amount of effort has been devoted to the development of reliable techniques Received in revised form for detecting gas leakage. As knowing about the existence of a leak is not always enough to launch 30 April 2012 a corrective action, some of the leak detection techniques were designed to allow the possibility of Accepted 21 May 2012 locating the leak. The main purpose of this paper is to identify the state-of-the-art in leak detection and localization methods. Additionally we evaluate the capabilities of these techniques in order to identify Keywords: the advantages and disadvantages of using each leak detection solution. Gas leak Leak detection
