How to handle on-site exhaust gas for hydrogen sulfide analyzers?

Thread Content

Recently, for a project, I lost a lot of hair on my head; it’s some kind of technical challenge I guess； Here’s the situation: It’s a gas mine that needs to have its hydrogen sulfide levels tested, and those levels are quite high. There are many instruments available on the market for such testing, but the owners are not satisfied with the solutions available for dealing with exhaust gases ； 1. Generally speaking, all hydrogen sulfide analyzers operate at atmospheric pressure; it is difficult to conduct measurements under pressure. Therefore, it is definitely not practical to reinject the gas back into the original pipeline ； 2. In the past, some manufacturers took advantage of loopholes in industry regulations by diluting the sample gas before discharging it on-site; but with stricter environmental regulations in place, this is no longer acceptable ； 3. The tested sample gas is directed to a low-pressure vent point, such as a flare; however, there is no flare on site. Additionally, it is said that not all gases can be sent to a flare – only those with a calorific value that meets the requirements can be used ； Instrument manufacturers sometimes also advise against accessing the venting device, as unstable back pressure downstream can lead to unstable measurement data ； 4. Using the conventional alkali solution absorption method, the owner mentioned that the facility is located quite far away; it is an unattended station at present, so replacing the alkali solution is a hassle, and these devices do not have any automatic alert function ； 5. When using a Venturi ejector, on the one hand, pressure is limited; on the other hand, instrument air is required on site, and moreover, other gas components may be introduced into the pipeline, which also has an impact on the components and their parameters that we have already measured or plan to measure. Dear experts, I think this is a promising research direction. I come from Sichuan Tailand Technology Co., Ltd., where we specialize in gas analysis instruments and various types of integrations. I believe that if this issue can be resolved properly, there is great potential in the market. I welcome everyone’s feedback and suggestions, and feel free to get in touch with me. Is there a loss-free, physical method for treating exhaust gases? Or is our conventional approach simply wrong in terms of strategy? I welcome any suggestions ；
