    keyword=Tech: ethane/argon gas pressure

    The ethane/argon mix passes through a low-pressure regulator sitting on the BB stack before it is fanned out to the three chambers. The pressure gauge on that regulator is only 1psi (on a scale from -30 psi -- +30 psi) with the regulator full open.

    This must be the source of the problems. The pressure from the gas shed is so low that atmospheric fluctuations play a huge role. The flowmeter on the fridge in the shed is also pretty much fully open.

    Can we increase the ethane/argon pressure in the line to get at least 5--10 psi down at the stack? We will have to pay attention when we do this (of course) or we run the risk of blowing the oil out of the bubblers since all the valves downstream of the gas shed are pretty wide open.
