Development of a Van-Portable Remote-Sensing Laser System for Selective Detection of Natural Gas Leaks

摘要

The overall objective of this multiphase project is to develop a mobile leak-survey system for gas mains buried in the street that is faster and more efficient than existing systems. The objective of this Phase I study was to demonstrate the feasibility the laser remote-sensing technique for selective detection of leaking natural gas. A laser breadboard system was developed using a spectral differential absorption technique for detection of ethane from natural gas leaks. The system was then successfully demonstrated using an outdoor simulated gas leak. To estimate system performance, a preliminary system analysis was performed.
