Well, I had planned to abandon my Propane refining and just buy some real HC refrigerants. In Aus we have a company by the name of HyChill that sells the real stuff, and will let it go in 9KG bottles, so I got in contact with them in order to purchase some. The thinking of course was that it's simple hydrocarbon gas, however at $50 per Kilo + $150 per 9KG cylinder (they wanted over $900 for a 9KG of R290 and a 9KG of R600a), I'll keep doing it myself.
Hells bells.. I can buy R22 on the black market for less than that! If that's the price of Hydrocarbon refrigerants, it's no wonder fridgies keep selling the flourinated stuff. There's no cost incentive to change at all.
My filtered and cleaned BBQ propane works out at $27 for the gas, and $50 for a very large filter drier, plus some time. Now as this is a hobby I can write off my time, and come out with "clean enough" gas at less than $9 / KG
