Hi all,
Does anyone have some experience with a reliable pump type (and possibly reputable manufacturers) for high pressure/relatively low flow applications. I require one to pump 2 m3/hr (9.2 US gpm) of 90°C (194°F) water and generate a head of 750 m (2460 ft) ~70 barg. It will run 24/7, be...
Hi all,
If a conventional valve is set pressure of 10 barg and has a 10% blowdown, it operates with a superimposed backpressure of 0barg, it should reseat at 9barg.
What if the exact same valve now has a superimposed backpressure of 0.5 barg, would it still reseat at 9barg or would it reseat...
Hi,
Does anyone have a sterile vent filter on any of their vessels vents?
How long do they last until they block-up and what are the inflows and outflows from the tank?
I understand that there are more factors that will affect how quickly the filter would block but I just need a very rough...
Hi all,
I am considering a shell and tube heat exchanger with water in the tubes at 4 barg and hot oil in the shell at 1.5 barg. In case of tube rupture, I know water will flow from the tubes into the shell containing hot oil at around 250 degrees celsius. For pressure relief of the shell in...
Hello all,
I have a pressure filter vessel with a PSV mounted on a 7" long spool from the vessel. As the vessel is a filter, solids-rich liquid (especially filter-aid) gets trapped in the spool and over time, the spool gets clogged with solids to the point that valve operation is compromised...
Hi,
Can anyone help me with this problem:
Batch of liquid product in elevated tank needs to be filtered through plate and frame filter to barrels. Currently, gravity is used to drive the liquid through the filter but there's usually some left in the filter and pipework afterwards and I need to...
