    Booster pumping in series questions

    TDH is total dynamic head, the "total equivalent height that a fluid is to be pumped, taking into account friction losses in the pipe. TDH = Static Height + Static Lift + Friction Loss."

    Moisture Level - Carbon Steel

    "Pure water alone cannot cause corrosion" That is not entirely the case. Demineralized water, distilled water, and even good old potable water can all be corrosive to common piping materials without anything special going on.

    Campaign Plant Design

    That is correct, EmmanuelTop. Frequently employed in fine chemicals and pharmaceuticals, a product is produced for a time or batch count (the campaign) and then everything is cleaned out and a different product or variation is produced for another campaign.

    Colour used for hand marked updates to engineering drawings

    My experience matches the majority: Red to add, green to delete, blue to comment. My first Designer was adamant on the subject, and it stuck.

    Pressure Reduction in series

    Unless I'm missing something, I'm not hearing a big problem here. Variable flow, variable inlet pressure, and you've already addressed that once with the variable flow and variable inlet pressure to your main reducing station.

    Soft seat ball valves

    I'd look for a nameplate and then consult a manufacturer, vendor, or manufacturer's website.

    Can FCV replace Frequency drive

    Power consumption is the first thing that jumps to mind; running with a VFD means you are trying to target the output by modulating how you run your pump. Using an FCV means you're running your pump at speed and braking the output to push it along its curve.

    Internal lining of Steel gate valve

    I read the original requirement and your revision the as the same requirement. Lined valves demand rubber-lined wedges. If you need a lined valve due to process requirements, that valve will require a rubber-lined wedge. If steel will not withstand the process conditions, do not use unlined...

    Internal lining of Steel gate valve

    My thought is that the concern is wearing of the lining where the wedge contacts the body. A rubber-lined wedge would mitigate this.

    Reading

    I typically cover-to-cover (C2C) technical books. To keep my attention high and get the most out of my reading, I typically read them in 10-page increments and have a spreadsheet open to take notes in.

    Must have technical references for new engineers

    Like MatthewL, I have a copy of Felder and Rousseau I use frequently. I also recommend Lange's Handbook of Chemistry. For the Project Engineer, I recommend: Planning, Estimating, and Control of Chemical Construction Projects by Navarette and Cole (get the 2nd edition, not the 1st, which was...

    Good mobile apps for engineers?

    TechCalc is a good scientific calculator. Graphing, a quick converter, and a built in Periodic Table.

    hot tapping for H2S VALVES

    The bulk of your focus should be on safety. H2S is an extremely hazardous material. If at all possible, lobby to empty and purge this line before you perform this exercise.

    Total Productive Maintenance

    Books often stay at home. A smartphone's pretty much always in your pocket. It was one of the nicest things about Droids back when they had USB Mass Storage capability: you always had a thumb drive with you.
