Lowering pressure for LPG
Lowering pressure for LPG
(OP)
What process or machine are used to separate propane or butane from LPG?
Is there a machine or process that lower a LPG pressure?
The current state of the LPG is 21% Propane & 79% Butane. It range from 6 bar - 7.5 bar, sometimes even higher. Is there any way to lower it below 4?
Thank You

RE: Lowering pressure for LPG
To reduce pressure increase Butane in the mixture, or lower the mixture's temperature and ... keep it low.
see the attached propane-butane mixture table

RE: Lowering pressure for LPG
30% Propane
70% Butane
at 80F
should be more like 55.5 rather than 45.5

RE: Lowering pressure for LPG
but the chart that you gave me is differ from the LPG pressure I'm currently using.
for example: 20/80 @ 80F 43.9 PSI (roughly 3 bar). But the one I have is 21/79 @ 80F 89.9 PSI (roughly 6.2 bar)
any explanation on the huge difference? some of the engineers i'm working with suggesting to increase the propane instead.

What is the source of your chart?

What process or machine are used to separate propane or butane from LPG? Its called distillation.
Is there a machine or process that lower a LPG pressure? Yess, it's called a refrigeration system.

Your charts may not match because of
1) what are the units of percent, weight, volume, or mole?
2) what is the butane, iso, normal, or a mix?
