Vessel sizing

Vessel sizing

Vessel sizing

(OP)
Hello,

I just want to ask any process engineer as to what would be an appropriate sizing for a horizontal pressure vessel, to be put in a pit, having a nominal volume of 6.7 cubic meters.

Operating pressure : 5 Kpa
Design pressure : 3500 Kpa
Corrosion allowance : 5 mm
Specific gravity of fluid : 0.984
Heads: Elliptical

RE: Vessel sizing

What is the actual process stream the vessel is part of? What is the throughput and/or required retention time? What is operating temperature? Should be a fairly straightforward pressure vessel calc if you have all that info.

RE: Vessel sizing

Around here- probably 4' to 5' diameter in that capacity range. If it just doesn't matter, specify the capacity and let fabricators pick the most economical dimensions.
The 5 kpa operating/ 3500kpa design seems a bit odd, but can be done if desired.

RE: Vessel sizing

From the engineering point of view, the vessel size, diameter vs length, may be based on several factors, such as process condition, instrument control requirement, physical space restriction, etc. you may consult with PE as well as the ICE and Civil for a optimum solution.
