    H2S Levels in Natural Gas

    Important, Thanks for the info re your gas specs. What Trond mentioned above is what I do. Chemical Engineer for a Canadian chemical company specializing in H2S sweetening. While your H2S concentration is feasible to treat via scavenging technology your volumes(200MMscfd) are significant. Ball...

    H2S Levels in Natural Gas

    There are many ways to sweeten varying in capital and op costs...what's your concentration, gas flow and pressure? CMo

    Cooling of Exothermic liquid reaction

    Wow, Thanks Art, good information to absorb. In regards to the heat rate, the 8 MMBtu/hr quoted above is not enough? I can try to track down more info. You are correct that we don't have access to CWS. Also our ambient temps have the potential to reach -40C at some points in the winter which...

    Cooling of Exothermic liquid reaction

    Sorry I'll try to add a little more detail. To sets of liquids are contacted via a static mixer from separate tanks, cooled and returned to a third separate tank. From the heat of reaction ~600 kJ/gmole we are experiencing a high temperature increase when we are attempting to keep the bulk...

    Cooling of Exothermic liquid reaction

    Hey There, I have a liquid reaction that needs to be cooled. I deal with natural gas processing but need a more tailred cooling process for this liquid medium. Any suggestions on type of cooling application to implement and some fabricators who build them North American based? Thanks in...

    H2S Levels in Natural Gas

    Trond, I deal with processing and sweetening marginally sour gas throughout Western Canada in concentration of H2S similar to yours as well as +/- an order of magnitude. While all gas plants and most remote locations have lel monitors on the ceiling and H2S monitors on the floor it is mandatory...

    H2S Levels in Natural Gas

    Trond, Meeting NACE standard will be your biggest concern since you can have corrosion issues, stress cracking specifically. I believe the standard is that the partial pressure of H2S must be below 0.05 psia for sweet service equipment. That means at 600 ppm your overall pressure must be...
