    LPG line Pressure Drop Calculation

    Hi Latexman, Pls find attached my calculations. The schematic diagram had been attached in my earlier post as shown above. Hopefully, some comments would shed light if my calculations was done on the right path. Many thanks...

    LPG line Pressure Drop Calculation

    Many tnx for the prompt reply, Latexman. Actually, what will be discharge first from the cargo ship to the Jetty manifold is refrigerated Propane which has a boiling pt. of -42deg.C then, followed by Butane. From the Jetty it will drop down to seabed where it will be heated by the seawater temp...

    LPG line Pressure Drop Calculation

    Hi Biginch, - belated Happy New Year! I would like to agree with you but there's no way to escape something embedded and left undone at the back of my mind. Pablo is great but he's also human,.....is to err!

    LPG line Pressure Drop Calculation

    Hi Latexman/Cloa - indeed, many tnx for the prompt reply. I just had a meeting with our client and there have been several developments/options in the project. I'll get back to you after I had consolidated all the data and the sketch. And yes,sorry,it's 2,000 meters (now 2,900 approx.). Propane...

    LPG line Pressure Drop Calculation

    Happy New Year to my colleagues! I was given an assignment to calculate the pressure drop on a 10"ND pipeline where 600MT/hr of refrigerated Propane (-42deg. C) would be discharge from an LPG cargo vessel (via 2,000 KM of submarine pipeline) at the Jetty then, goes 45deg upwards diagonally then...

    LPG Unloading

    Hello dear colleagues, The scenario is unloading of LPG from a cargo vessel(ship?)to several LPG Storage Tanks (bullets)at a distance of approx. 4,000meters. - do we need a reheater and booster pump? - do we need an Ethyl Mercaptan Injector? - do we need a mixing tank? Many thanks indeed.

    Oil & Water Separation

    Hello to my colleagues, Whilst waiting for some data from my client, I had a chance to talked to an Operator of an Oil Depot which consist of several storage tanks for different petroleum products. I was told that during product offloading from the tankers at the pier, some water is picked-up...

    Oil & Water Separation

    It was indeed quite a substantial saving opting for the atm tank! Does this cost include a Pre-treat tank? I'll get back to you when I had received the data that I had requested from my client. Many thanks again, David!

    Oil & Water Separation

    Thanks much indeed David, for the gun barrel pics. So, both gun barrel tank & 2 phase separator work on the same liq/liq separation principle? Am I right? Appreciate your comments on what basis and justification do I have to choose one from the other? Though not important, am also thinking why...

    Oil & Water Separation

    Hi Shahyar, As of this date,I am still waiting some feedback from the client regarding the required parameters (capacity, temp., pressure, viscosity, density, etc.)for the design of the Processed Used Oil System. As I initially understand, the term "Processed Used Oil" means that the oil (used...

    Oil & Water Separation

    Hi David, It was great relief knowing none of those I thought of in separating oil & water is recommendable. I'll appreciate it much if can go further in providing some more details on how to instal a weir gate or weir nipple and an oil skim line. Sorry for the inconvenience but honestly, I've...

    Oil & Water Separation

    Hello, I am designing a system where Processed Used Oil will be shipped via a Lorry and will then be pump to an atmospheric storage tank. From the tank, it will finally be delivered to the end-user for use as Fuel Oil. I am not sure whether to provide an oil & water separator upstream of the...

    Decommissioning Procedure for Cryogenic Tanks

    Many thanks again, dcasto. Actually, it's an ethylene and a propylene storage tanks that will be decommission for preventive maintenance with some repairs to be done. I understand your advice but it's too generalized. Appreciate if you have a more detailed procedure from your Operations group...
