Assuming that the information is accurate, I have been pondering over a few more issues. Assuming that the "petroleum based hydrocarbons " are in the air from the compressor, do the hydrocarbon particles stick to the walls of the tank or do they remain suspended in the gas? Plus how much "petroleum based hydrocarbon" is required to be present for chemical ignition to occur, i.e. will one little particle do it? My concern isn't so much the minute detail, but if the hydrocarbons don't stick to the walls of the tank by draining the tank would it eliminate the contamination issue if hydrocarbons for some reason are present? Or if they do stick to the tank then should the concern be whether the air is filtered clean, rather than whether the tank is clean? Or am I totally off base here?
