Even more relevant, Optical Gas Imaging devices are pointed by the international authorities (EEA, EPA, etc.) as the Best Available Technique (BAT). This fact confirms that the classical EPA Method 21 (based on sniffers) is being replaced by Smart LDAR (based on OGI).
However, the industry in whose processes SO2 gas leaks occurs, has not yet taken the step. SO2 is present in the chemical, copper, food, paper and food industries. It is also found in the production of sulfuric acid for metallurgy as a drafting agent. Its greenhouse effect is well known, sulfur dioxide has a harmful effect on the environment, causes acid rain and is highly toxic.
The same forces that drive the implementation of Smart LDAR in other fields apply in the sulfuric related industry. However, the factor that has avoided incorporating the use of OGI in LDAR tasks in this industry has been the lack of equipment. CAROLINE Y comes to fill this gap.
