    Coker charge valves

    Does anyone have any experience in specifying coker charge valves? Currently our client is using Fisher CV500 ball valves, which only last about two weeks. Any information would be appreciated. --Igor

    Inherent Control Valve Characteristics

    shobi, thanks for your reply. I understand the relationship between valve opening, CV, and flow. My question is how do you determine which valve characteristic: 1) Linear 2) Equal Percent 3) Quick Opening Is best suited in an application basis. I'm not...

    Inherent Control Valve Characteristics

    Can anyone provide me with a a web link, book refrence, or any experience in how to choose an inherent valve characteristic when designing a control loop? I've posted this question in other forums only because I didn't know this forum exsisted until now. Anyway, this is what I know: Control...

    Anyone have any RECENT experience w

    I don't have any experience with Foundation Fieldbus but my supervisor does and he is a strong advocate of it. He did a SAGD project up North that was a Foundation Fieldbus project. I talked to a few people I knew at site as well as what my supervisor has stated and it seems it's the way to...

    P&ID Information

    jsummerfield, in my opinion I wouldn't go into that much detail on a P&ID. I would show the limit switches and solenoid valves, and even the manual resets but I wouldn't show where they are wired from. As far as the P&ID goes, in my opinion, that is information that isn't required. Moreover...

    P&ID Information

    RGCook, I can't send a copy of a P&ID due to licensing agreements with End-User companies. However, if you give me you're email address I'll send some PDF "sketches" showing these examples. My email is: cornejoi@bantrel.com Regards, --Igor

    Intepretation of ISO 5167-2:2003

    I would take the standard at face value if I were you. Everyone loves using orifice plates because they are supposedly cheap and nasty and accurate. This statement is not true when you consider installation costs if you require accuracy. Such is your case. The reason that I would treat the...

    Steam Mass Flow Transducer

    The problem with using Orifice plate to do ANY mass flow is the straight pipe requirements needed in order to ENSURE that you have your accuracy within the required limits (Read AGA Report # 3). Moreover, even when installed correctly and configured (You properly sized your orifice plate, the...

    Remote I/O

    Hey guys, I'm helping out in a study that's comparing Remote I/O to Fieldbus. The problem is that I don't know too much about Remote I/O. Can anyone suggest a web site that I can go to where I can read up on Remote I/O? I'm just looking for a broad overview. Thanks guys. --Igor

    Radioactive Level Measurement

    If you are looking at non-invasive technology, couldn't you also try an ultrasonic or radar mounted at the top of the tank? I've never had to specify anything in HF service, however I know how nasty it can be. How about a guided wave radar? Calibration is relatively simple, the wave guide...

    P&ID Information

    I work for an EPC company that has several end-user companies as clients (ie: Imperial Oil, Shell, Petro Canada, Chevron, Husky, ect). Each client has different prefrences of what they want to see on the P&ID's. Some client's prefer to only show the bare-minimum of what is necessary. ie...

    Straight run requirments for various flow meters

    PD meters aren't an option. It's not that I don't believe in them or anything, but I'm in an engineering consulting firm and I'm doing a project for an end-user(end-users are companies like Shell, BP, Imperial Oil, ect). End-users ALWAYS have prefrences on what type of meters they prefer...

    Straight run requirments for various flow meters

    Hey guys, I'm preparing a table my piping group so that they know ahead of time what the straight run requirements (upstream and downstream diameters) are needed for the different flow meters that we will be installing. Can anyone guide me to where I can find a good place to look up these...
