An inexpensive imaging instrument to quickly locate leaks of methane and other greenhouse and VOC gases would reduce that cost and effort expended by industry to comply with EPA regulations. In Phase I of this SBIR program, a new gas leak visualization camera was demonstrated using Agiltron¿s infrared image sensor, which our company has under advanced development and expects to manufacture in large volumes at much lower cost than any existing technology. In Phase I, using methane as an example target gas, we were able to detect leaks on the order of 10 SCFH with only ambient IR illumination, by using our sensor together with proprietary methods of optical filtering and image processing. Building on this proof of principle, the Phase II prototype will be 10X more sensitive and entirely free of false alarms. The final product will be smaller, lighter, and much less expensive than any competing system, about $2,000 end user cost compared to $70 - 100K for currently available solutions. This will enable wide distribution in industries such as refineries and pipelines and for local businesses including natural gas maintenance, supermarkets and automotive and HVAC repair shops. In addition to methane, a wide variety of gases with absorption bans in the 6 ¿ 12 ¿m IR range can be detected including SF6 and refrigerants, supporting compliance with EPA regulations for VOC and greenhouse gases. The unit is switched in sensitivity form one gas to another with a user-changeable filter. In Phase II Agiltron proposes to develop and test a prototype methane product which will incorporate sophisticated software algorithms and optimized optical designs to reach higher sensitivities along with ruggedness and east of use. An LCD display will show an overlay of the gas leak plume with an ordinary visual image, making it easy for relatively untrained personnel to locate leaks very quickly. The performance of the instrument will be verified by a third party laboratory.
