    Storm Water Treatment

    What volume of water are we talking about. Would a surge drum between bund and separator help you out? Are they regular CS, atmospheric, ambient temperature storage tanks? How often would you expect to have the tanks exposed to high rain water level? what level of rain water (above tank...

    scrubbing bio gas

    A bit obvious perheaps but: -Have you got enough pressure to overcome the controls inside the boiler? -Have you played with the fuel to air ratio? -How is flame detection done in the boiler? Martijn

    Vapor Condesner with subcooling

    What you typically do is have a temperature controller on the outlet, which controls an upstream aircooler. Keep the cooling water flow constant. If you don't have an aircooler upstream, and the turndown on cooling water is limited, you can control the cooling water flow. (be carefull for...

    Steam Generation from Tower Condenser

    @Yitbos: because it is an existing situation. It appears something you could consider for a new project, although I've never seen it outside my fridge :-) @SShep: Regarding a vertical thermosyphon, i refer back to my previous post: have a look at the required control scheme. I don't see how to...

    Produced Water tank blanketing

    Simply relying on a pressure regulator wouldn't make me feel comfortable. I've seen several pictures of tanks looking like crushed cans...

    Produced Water tank blanketing

    The problem wth backflow from the flare is that you don't know what's in it. condensable HCs? H2S?, NH3? Other things that can pollute the water or corrode the tank? I don't think there's a general accepted standard on blanketing, it is just good engineering practice. (with API 2000 giving the...

    Produced Water tank blanketing

    I suspect you're talking about an atmospheric storage tank. Consider the following: -Tanks can't handle well negative pressure. Filling it with fuel gas makes it hard to use a straight-forward vacuum breaker (FG + air = awkward). -Hanging an atmospheric tank to a LP flare leads to a very...

    Gas treatment unit design

    I agree. I don't know how tight the required spec is, but you can better ask a pro and be sure it works, instead of DIY'ing a thing that doesn't work...

    Converting European VOC emissions to ppm

    Although I'm not the expert on this there's one obvious difference. g / m2 h is mass based. ppm (when talking about concentrations in air!) is typically volume based. Different VOC's have different molarmasses (g/mole). So unless formaldehyde is your main component which is released, you need...

    WATER COOLED HEAT EXCHANGER TEMPERATURE LIMITATIONS

    Usually it is cheaper to install an aircooler with a small watercooler behind it. (Of course depending on the size of the process flow you want to cool)

    Steam Generation from Tower Condenser

    Depends a bit on the plot layout off-course, but as gr2vessel says, you will probably end up with a BKU / NKN type condenser. I don't know what you are condensing, but have a think about the control scheme. You might want to keep your aircoolers if outlet temperature is to be controlled.

    Sizing normally dry KO Drum

    1: depends on your upstream system. Can you get liquid carry-over from an upstream drum, or is it condensation only. If you can get liquid from an upstream vessel you would take x seconds of liquid-full flow. (x depends on safeguarding) The resulting liquid volume should fit in your vessel. 2...
