No worries here. If you're using a standard a/c compressor, they have a mini-suction-accumulator built into the muffler on the suction line. If the evaporator burps, the foamy froth goes into the bottom section of the muffler, rather than being ingested by the compressor. So unless the evaporator is vomiting, you should be OK.
Another thing to remember is that the regular, blow torch or bbq propane has "stink oil" mixed in (it is somewhat soluble/miscible with propane) the bottle. So if you don't want lots of oil, charge slowly with the bottle upright. Oil is heavier than propane, so it will sink to the bottom. If you shake the bottle, guess what happens? Lots of oil leaves with the gas.
