*Modular System for Direct Conversion of Methane into Methanol via Photocatalysis* This two-year, proposed by Stanford University, will develop a process for photocatalytic activation of methane at a gas-water interface such that methanol can be formed at ambient temperature. The modular reactor will be developed to use pressurized gas through a photocatalytic membrane wall supported on nano-porous polyethylene. Under standard ultraviolet light, hydroxyl radicals will be generated that then create subsequent methyl radicals that can be synthesized to methanol by a co-catalyst also in the reactor wall. The methanol then dissolves into the liquid phase portion of the reactor to avoid over-oxidation. This project’s task list includes optimization of the bi-functional catalyst to achieve high selectivity and methane conversion efficiency at ambient temperatures. *Key advantages of the proposed method include:* • Methane to methanol conversion demonstrated with 90 percent methanol selectivity, 5 times higher than other state-of-art liquid phase reactions. • Overcomes reaction kinetics limitations and water extraction requirements of gas-phase reactors that employ stepwise oxidation of methane to prevent over-oxidation. • Liquid-phase solvation helps stabilize products and critical intermediate compounds. • Use of photon energy allows for low-temperature reaction. Reactor layout and process diagram are shown above.

#thoughtfulthursday Inspired by the story of Einstein and his teaching assistant. You know the one... where the assistant asked Einstein why he gave the same test to the same class 2 years in a row, to which the genius replied… “Because the answers are different.” Now, before you all start piling on, I know I’m no Einstein, but here’s the thing. We can all be inspired to revisit stuff we know to see if there’s an alternate, better option, to do best for your customers. Enough rambling… 25 years ago, the best solution to scaling induced by high pH H2S scavenger application on sour gas production was to add a scale inhibitor into the formulation. SPE Paper Number: SPE-71541-MS. Referenced many times as the industry-leading solution to a tricky problem. If you think it might be too difficult to read, try running the field trial, managing the application, and co-authoring the paper. #iykyk The only issue was the fixed ratio of scavenger to inhibitor that had the potential to still do the job required, but tricky to optimise on a well-by-well basis. So, 25 years on… what if I suggested you could potentially ditch the combo chemical and use only the H2S scavenger in an optimised application. What about mitigating the scale, you ask… Well today the answer may well not be a chemical inhibitor but ClearWELL™. If you want to know more click on the links here or DM me. Happy to chat and see if we can assist you.

Recent advancements in magnetic separation technology have significantly enhanced its application across various industries, including oil and gas, manufacturing, and power generation. For instance, a study published in the Journal of Petroleum Technology highlighted the use of magnetic nanoparticles to remove dispersed oil from produced water, demonstrating the potential of magnetic separation in improving water management practices in the oil and gas sector. https://lnkd.in/eVvzjiN6 Additionally, the U.S. Environmental Protection Agency has explored the application of high-gradient magnetic separation to fine particle control, indicating its effectiveness in removing small, weakly magnetic particles from nonmagnetic materials. https://lnkd.in/eaMiruWC These developments underscore the growing importance of magnetic separation technology in enhancing operational efficiency and environmental compliance across multiple industries. #MagneticSeparation #TechnologyInnovation #OilAndGasIndustry #EnvironmentalTechnology #WaterManagement #IndustrialEfficiency #CleanTech #Nanotechnology #EPAResearch

STRIPPING TECHNOLOGY FOR LIQUID AND GAS TREATMENT: HOW DOES IT WORK FOR WASTEWATER AND CRYOGENIC GAS CONDENSATION? Stripping is a process in which wastewater interacts with a gas stream to transfer volatile pollutants from the liquid phase to the gas phase. However, these pollutants, which can be solvents or a mixture of substances, cannot simply be released into the atmosphere and must be treated appropriately. This conversion from liquid to gas is often advantageous because treating pollutants in the gas phase can be simpler, especially when they are diluted in water. A notable example is the combination of stripping with cryogenic condensation ❄️, as illustrated below. This method is particularly effective when dealing with chlorinated or fluorinated organic compounds in water, whose treatment in the gas phase using other technologies can be challenging. By using liquid nitrogen in the condensation stage, nitrogen gas is produced, which can then be reused in the stripping process in a closed-loop system. In a study led by Sadeghifar and colleagues, a mathematical mass transfer model was developed to assess the potential of packed towers in lowering contaminant concentrations to permissible levels. The model uses a resistances-in-series approach and accounts for liquid-vapor equilibria through temperature-dependent Henry's constants. It was validated against various experimental data. The study valuated the effects of key parameters like: 🎯 Column pressure 🎯 Temperature 🎯 G/L ratio 🎯 VOC inlet concentration 🎯 Tower height Each of these factors plays a crucial role in the process. For example, column pressure can significantly affect the efficiency of VOC removal. The higher the pressure, the less effective the stripping process tends to be. Temperature also has a profound impact. Generally, higher temperatures increase the VOC transfer to the gas phase. These parameters interplay to influence the design and operation of this type of towers. The study investigate the importance of tailoring each of these factors to specific requirements for optimal VOC removal. 📚 Discover more about recent trends on cryogenic technologies in my Linkedin article: https://lnkd.in/eMEqbmRe #StrippingTechnology #WastewaterTreatment #CryogenicCondensation 👇 I find this integration and scenario interesting.
