    Jacking Oil Pump Air Lock Bleed Valve

    Hi, A few comments: -Nothing wrong to start a pump from field, except for lazy operators, -To me the location of the bleed is wrong, assuming centrifugal pump, should be on the discharge line of the pump, between the manual valve (isolation valve) and the check valve this will allow to bleed...

    Gas Pipeline faces Higher velocity in pipeline network.

    Hi, Consider this document to support your analysis. About formula of velocity in SI units, consider this one: Velocity(m/s) = QM (kg/s) *Z*R*T (K)/ [Mw (kg/mol) *P(Pa)*A (m2)] with R=8.314 (SI) Mw molecular weight. Pierre

    Gas Pipeline faces Higher velocity in pipeline network.

    Hi, Where are the data coming from? Calibrated sensors? Did you perform a mass balance to confirm/consolidate the values? Can you sketch your system for us to visualize better? Do you have operation issue or it's just for clarification? Pierre

    Dew point for RNG

    Hi, Consider these resources to support your work. Note: I'm not sure about the issues being Analyzers or Process. You may need to consider in line analyzer to monitor H2O content (infra-red sensor) and or GC (talk to representative from Perkin Elmer). Pierre

    Is there a comprehensive chemical odor threshold database?

    Hi, For the reasons explained above by Matt, I relocated a plant from Australia (Melbourne area) To Thailand. The chemicals were Ethyl acrylate and other acrylates. Pierre

    Real or ideal cp/cv for orifice sizing

    Consider the document attached in particular slide 7. Your statement about safety valve and use of ideal values of Cp,Cv is incorrect. Pierre

    Real or ideal cp/cv for orifice sizing

    Hi, Yes, must be real exponent k=Cp/Cv. You may want to use an EOS like Peng Robinson to calculate them. Pierre

    U-bend before pump suction inlet.

    Hi, I don't think the diameter of the pipe is big enough to be a priming pot! http://www.rhodekpumps.com/priming-pot.html Pierre

    Process Chill Water Loop for Multiple Machines with varying requirement.

    Hi, nice bow ties on your drawing, kidding! You need to perform a full hydraulic study, 2 inches pipe for header is too small. Pressure on the return line should me manage (PCV) to ensure all users get sufficient enough water. My 2 cents Pierre

    Wet scrubber - what happens if you continue to re-circulate a scrubbing liquid?

    Hi George, It was also one of my questions (last post), should be hPa m3/mol. https://www.henrys-law.org/henry/ I believe the OP is a student ...... Pierre

    Two Pumps of Different Product and Ratings Pumping into a Common Header

    Hi, Agree with Snickster. Start from scratch! Why does this job not handle by the process engineer? Share with us a relevant sketch and process data, the way works engineers. This will save words and mitigate errors. Good luck Pierre

    Is there a comprehensive chemical odor threshold database?

    Hi, Some data about acrylic esters. Those materials, in particular EA, have a strong odor at very low concentration. Try this link: https://aiha-assets.sfo2.digitaloceanspaces.com/AIHA/aihaconnect/Educational-Books-Preview/Odor-Thresholds-for-Chemicals-43-PREVIEW.pdf another reference : Odor...

    Wet scrubber - what happens if you continue to re-circulate a scrubbing liquid?

    Hi, Did you hear about Google? https://www.kianresin.com/userfiles/files/eastman_Dimethylformamide%20(DMF).pdf many more data are available! Do you know that Henry's coefficient has a unit? Did you check the MSDS of your product and acceptable threshold for releasing this material to atmosphere...

    Compensating pressure in Cryogenic Storage Tank

    Hi, To add to my previous reply: https://www.pijttersen.nl/downloads/CO2%20Design%20Guide%202-9-2012.pdf. Take also a look at air Product paper, they mentioned coil pressure built up. You may want to contact them. Pierre

    Wet scrubber - what happens if you continue to re-circulate a scrubbing liquid?

    Hi, Probably good for you to review this document. If you don't add make up water, the level of water in the sump will decrease because the gas leaving the tower is saturated. You will damage the pump soon or later. Other consequences, viscosity, charge of pollutant, superficial tension will...
