Thanks for the useful info. Would it work better for me if I drop the pressure to 800 psi or so before I send it through an orifice?

I can always power an engine-driven genset with the gas - I just don't have a continuous application for electricity. Plus I didn't want to maintain...
I have a large volume of (free) natural gas sitting at 5,000 psi. I'd like to pass the gas through an orifice, give it room to expand on the backside, and use that to chill glycol. I would like to drop the output pressure to 100 psi in the process.
I wish to use the chilled glycol to cool...
