    Storage Tank - Extended life

    Can one apply a FRP lining (or other thick plastic liner - like a pipe liner) to a corroded tank to satisfy API 653 thickness requirement?

    Keep information in an organized form

    To be a successful Project Manager - you need to be organized. Some may agree and others disagree, but when you consider that a PM should (theoretically) control only two (2) activities-Time and Money (Budget and Schedule) it seems like an easy well paying position. BUT - most companies give...

    Fire Protection Spray Rings

    With several years of fire suppression system design under the belt a good suggestion is to start with NFPA 15 - Water Spray Fixed systems for fire protection. As the type of tank is not given - i.e. cone roof with internal pontoons, floating roof etc. the most economical (recommended) system...

    API 620 tank design

    Recently I read an "in house" storage tank specification which ended up a mixture of specifications. The intent was good, but one cannot short circuit the tank selection data, design requirements, and installation preference for any particular company. These all need to be separate, but can be...

    Pump type selection for a viscosity of 6000

    Here is the additional information - mostly assumptions as the information is from the PFD's and the process data sheets have not been developed at this stage - Pressure - 160 feet H2O column Temperature - ranges from ambient to 250°F (heated and non exothermic during mixing)

    Pump type selection for a viscosity of 6000

    Shame on you !!! This is America and the standard units for viscosity are cP (Centipoise) and for density is lbs/gal - Thanks for pointing this out. I know that there are other units and there are some who prefer to work in metric units.

    FLA on a medium voltage motor

    We have a reconditioned NEMA motor - rated at 1750 HP 6000V 3 Ph 50 Hz (overseas application). The motor is about 730 ft from the MCC which is fitted with a soft start. The electrical system is supplied by 4 Hyundai generators rated at 6550 V 3 Ph 50 Hz. The elelctric motor drives a large gas...

    Reqirement for symetrical piping on the inlet of a CDU heater

    Hello popovic, The existing piping set up is fitted with 4 independent lines from a common header. Each leg is fitted with an orifice plate and a globe valve - to allow for "fine ture" balancing in each coil. What we have deduced is that we have excessive two phase flow - 8wt% causing...

    Reqirement for symetrical piping on the inlet of a CDU heater

    Emmanuel, The existing piping configuration does not lend well to the installation of control valves. We are looking at replacing the entire inlet manifold with a symetrical configuration. Wanted to know if anyone has done this on a small process heater (20,000 BPSD crude). Regards

    Reqirement for symetrical piping on the inlet of a CDU heater

    Has anyone converted the standard inlet manifold on a crude heater to a symetrical piping layout to eliminate uneven temperatures in the passes?
