The proposed are an imaging system and method for detecting hydrogen sulfide (H2S) in a safe distance. The imaging system includes an infrared (IR) imager capable of capturing an image of a scene that includes a gas plume, and a narrow bandpass filter installed in the infrared imager. The narrow bandpass filter has a spectral window. A width of the spectral window is in the range of 100 nm to 300 nm. The spectral window is included in a wavelength range between 2.5 μm and 2.8 μm, a wavelength range between 1.5 μm and 2.0 μm, or a wavelength range between 7.0 μm and 10.0 μm."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus for imaging hydrogen sulfide plume and method of the same","description":"As hydrogen sulfide is toxic and widely present in many oil and gas facilities, it is highly desirable to use an infrared camera to detect the presence of a hydrogen sulfide (H2S) plume from a safe di","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9671331","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
