I get it man. I’m busy over here too.
But you did have the time/energy to write out your whole OP.
And time to bump up other active vs passive threads while pointing people to this thread to buy your chillers.
If you pop up on the scene one day and make some new claims, it would make sense for you to respond to a rebuttal of your claims. Especially if you’re selling something.
Why not at least explain the CNG vs LNG thing?
I don’t think you’ve really provided sufficient evidence for a lot of what you’re claiming here.
Your OP just kind of stumbles into the idea of choked flow out of nowhere with no real context.
This is sounding a little like charlatanism to me. Or the confirmation bias thing.
Below is my work solving the given equation using the variables you provided for a 1/2" orifice in your last post.
The answer I get for max (choked) flow rate of butane vapor through a 1/2" orifice is 594 lbs/hr or about 10 lbs/min.
That’s not too bad by current industry standards for medium/large batch butane extraction systems, active or passive.
Most aren’t even close to that limit but some are.
I’m very confused by your chart.
For example, it looks like you are implying that the choke limit for butane vapor through a 1.5" orifice is 160 lbs/hr or 2.6 lbs/min.
If I solve the equation for a 1.5" orifice size (.001142 m2) using your given variables for pressure and density, same as I did above, I get about 5,351 lbs/hr or 89 lbs/min max butane vapor flow rate through a 1.5" orifice.
Why does your chart imply that the limit is only 160 lbs/hr (2.6 lbs/min)?
