    Venturi Meter design guidance

    I've been reviewing the ISO standard as recommended I noticed on the first page 5167-4, note 1 gives a caution against using Venturi's in high pressure gas service. Can anyone comment on their experience with this? Also I find no such note in 5167-3 for flow nozzles, I don't understand why...

    Venturi Meter design guidance

    The service is high pressure (850 psig) hot pure oxygen, we have various line sizes that we are considering using it it but the most immediate is a 4" line.

    Venturi Meter design guidance

    I've recently come across a Flow measurement application that seems suited to using a Venturi tube as the primary element (I need low DP and now sharp edges), I've used a lot of Square edged plates in the past but have never specified a venturi I have the proper software to do the calculations...

    Low Flow, High Pressure

    Until now I hadn't heard of a pitot pump, but after some time with Google I think it looks like an interesting option (that lack of pulsation would be great for our process) I was wondering if anyone could comment on the reliability of the pitot pump compared to a piston diaphragm pump? Also...

    Low Flow, High Pressure

    I am trying to choose a pump for the following conditions: Flow: 2-10 gpm Discharge Pressure: 1000 PSI Suction Pressure: 20 PSI Fluid: Low Viscosity (1 cp) organic I'm assuming that it is a job for a PD pump but I'm not sure which style. We use PD pumps elsewhere in the plant but they are all...

    Stripping MEA with "Live" steam

    We have a MEA stripping column in our CO2 removal unit with an extremely undersized kettle reboiler, a problem that should be fixed in our next turnaround but that is 18 months away and we are looking for ways to get enough heat into the column to operate at reasonable rates until then. One...

    Increasing capacity of a co2 removal system

    I support a syngas plant that uses the sulfinol process to remove CO2 (and very small amounts of H2S) from the syngas stream. I am in the process of designing an improvemnt to the plant that will allow us to increase syngas production by about 10% but the sulfinol unit is already at full...
