    Compressor Settleout iteration

    Looking at determining system pressure after failure of isolation of discharge pressure to suction piping(lower pressure rating). The calculation requires finding the final pressure. T final= H/(Cp*Total mass) - at settleout with combined suction and discharge masses and volumes P final =...

    PSV Dischrage Pipe

    Is it a hard and fast rule that the PSV discharge pipe be at least as large as the PSV discharge connection? I am looking at an as-built pump skid with a blocked discharge PSV -1"x1" - with a 3/4" connection to a 2" line back to the tank. Don't have API 520 with me and no discussion I have...

    Residence time for production test

    Greetings, I am in need of appropriate sources and assumptions to evaluate the residence time needed for producing a shallow sands oil to a test separator already serving test production from a deeper, warmer, less viscous oil. A cursory look at shallow well rates for oil, water, and gas...

    GVF vs GLR or GOR

    GVF is Gas Void Fraction not FVF.

    GVF vs GLR or GOR

    We found the definition of GVF, but it still didn't answer this question. What is GVF in comparison to GOR?

    API-14C

    Friends, I am designing well trunk and lateral systems and was wondering if there was a link to API-14C and was wondering if there was any other useful information outthere regarding design of oil production systems.

    Pipe length for tank for heating

    Patrickraj, Don't have that book. My fax is 907-273-3990 if you can spare a copy.

    Pipe length for tank for heating

    Saxon- I wouldn't mind having a copy of that for documentation. Mind sending a fax or snail mail? Mrepp

    Pipe length for tank for heating

    Thanks for the info Saxon, and you summarize the condition correctly. I was looking for something other than a derivation for this, count on Crane to get you a nomograph or something "practical" considering time given to do our "art" these days. Do you remember what the...

    Pipe length for tank for heating

    I am specifying a heater for a new tank. My bright idea was to use the glycol available at 180 F and route it through the interior of the tank in 2" welded pipe and coil it until the appropriate BTU's are transferred. Considering the tank has no mixing, assuming the fluid is stagnant, how...

    PD pump pulsation

    Trying to add a servuce to an existing PD pump. I am sizing a PSV off the pump and am pinched between it and the MAWP of the pipe to the point where the magnitude of the pulsation might not allow the PSV setpoint to be within the allowable 10% overpressure. Any relationship to predict the...

    Water Saturation at low temperatures & high temperatures

    Thanks 25362, that is the data I needed. I was looking at crane (which is most of the time), and it has limited data, my Perry's has some dust on it. Morten, good point, we should consider providing guidance for operating when the mol sieve drying unit is down in the winter time. We already...

    Water Saturation at low temperatures & high temperatures

    At 450 PSIG and -60 F what is the saturation concentration/ partial pressure of water? We trying to reduce the water content of a stream to prevent hydrate formation. It our understanding that water needs to be present to create hydrates. The HYSYS model runs out of significant figures for...
