    Many thanks guys!

    free chlorine measurement

    Hi, I'm struggling to find suppliers of instruments for on-line free chlorine measurement in water to ~300ppm best I can find is ~20ppm from the likes of ABB, Yokogawa, and others Before everyone says "that's helluva high", it is not for a water treatment application (is for makeup of...

    Hazardous area classification - biogas condensate lute

    Cheers Hoxton, I've got the ESA info, sadly it doesn't cover this type of arrangement.

    Hazardous area classification - biogas condensate lute

    Thanks Littleinch, I didn't think it was that rare a term! Hadn't considered using an additional restriction, will have a think about that sketch attachedhttp://files.engineering.com/getfile.aspx?folder=a439179e-dc5a-4b3e-b912-17865c4aab07&file=condensate_lute.pdf

    Hazardous area classification - biogas condensate lute

    Just reread my post and it is not the clearest ;o) Specifically, looking for any guidance or references as to how to handle zoning of a lute type arrangement, failing that opinions and/or any info on how other sites may have done this. Don't want to be chasing shadows OR missing a problem.

    Hazardous area classification - biogas condensate lute

    Hello all, I have a query for the collective minds. - UK installation - very wet biogas pipework at low pressure (~35 mbarg) - Several condensate collection pots in the piping system - Each of these has a lute i.e. there is no automatic or manual control of liquid discharge, simply the...

    flowplates / dial-a-pipes

    hi guys, thanks for taking the time to comment. Latexman - the proposed solution would eliminate the plate altogether and use routing valves so the person would not have to be anywhere near - and there would be no swingbends involved. Specific PHA / PSM requirements (I had to google) are not...

    flowplates / dial-a-pipes

    Hi Latexman, Routing manifold for transferring fluids between different locations using a swing bend or flexible hosehttp://www.pipeline-products.co.uk/media/images/news/700/94240_flow_plate_010.jpg

    flowplates / dial-a-pipes

    Hi there, I'm trying to find out if there is any guidance - regarding when it is would be recommended NOT to use a flowplate / dial-a-pipe type arrangement for routing flow. I have a flowplate in a food factory that has 4" piping and line pressures of >8 bar during the cleaning cycle (of 80...

    vent sizing

    I've not worked out how to edit posts - should have said "my poor knowledge of compressible flow" Sheet attachedhttps://docs.google.com/file/d/0B8gu7ww7yYy8MWxTMmI1LTkzR1U/edit?usp=sharing

    edit - my steam maths had an error so revisiting.

    vent sizing

    Hi all Thanks for all these replies! I've had a play about with what I can easily calculate without getting into too much complex heat transfer theory - it is a while since I had to do that kinda maths - and then come back here to see Stonecold's suggestion which is near as dammit what I came...

    vent sizing

    Hi Latexman, were it not for the fact that I have >20 existing tanks, I might agree! I know there are similar arrangements of hot CIP, cold rinse in many finished product storage tanks in the food industry, also e.g. road tankers for food products, but I can't find anything to define a sensible...

    vent sizing

    Thanks KvdW, sadly I don't think it does - the closest would be RJB32482's point but I can't see how to apply that equation to my problem (I may be daft, or over analysing it) as I think it is looking at heat losses from the tank causing the condensation, whereas I have an inflow of cold water...

    vent sizing

    Hi folks, I've been googling like mad for this, all I can find is various works for when there is cold spray on the outside of the tank surface condensing steam inside a tank... Any hints as to where I might find a solution more related to this particular problem? Cheers Col

    Vent size - vacuum relief

    Thanks guys for taking the time to view the thread. Some additional info I did not include in the original query as I thought it muddied the issue, I guess being from a food / pharma background I forgot that other industries don't necessarily have the same problems/situations and my wording...

    Vent size - vacuum relief

    cheers for that... but you can't have a manway open when you are high pressure sprayball cleaning the inside with 80 degC caustic solution...! we'd soon have a 10m spray of caustic across the roof of the factory! ;o)

    Vent size - vacuum relief

    Hello all, I've seen a few similar-but-not-quite-the-same threads so here goes. I'm trying to confirm size of a vent in a ~70 m3 atmospheric tank which sees a range of temperatures and is also cleaned at 80 degC followed by a cold rinse. (There's direct steam injection too but I'm trying to...

    316 and Brine

    thanks folks for quick response! Most valves are butterfly, no threaded bits (all welded except a couple of hygienic unions). Will keep an eye on it rather than scream!

    316 and Brine

    Hi, A contractor has installed a section of pipework, control valve, flowmeter and isolation valves in 316 stainless steel (may be 316L not sure). The duty will be saturated brine at ~10-20 degC. It is ~1" line and will see a reasonably constant flow for most of the time but possibility of...
