F. Guffy, while I don't want to get off the topic, before I retired, we had gone to tank bleeds which automatically would bleed the condensate (moisture) in our storage tanks. While air was used for pneumatic valves and such our biggest use was high pressure dry pumped nitrogen. Anyway, the automatic bleed systems were working well when I retired. Checking them is also part of a check list that is followed each shift change.
