Abstract:
A method for filling one or more cylinders with a process material using a filling apparatus comprising a source of purge gas, a source of process materials, and a manifold in fluid communication with said source of purge gas with said source of process material, and with a holding tank, said manifold operatively connectable to said cylinder and said manifold are in fluid communication, said method comprising the steps of:(a) pressurizing said manifold with said purge gas; (b) depressurizing said manifold; (c) connecting at least two cylinders to said manifold; (d) displacing said purge gas within said process material; and (e) filling at least one of said at least two cylinders, leaving at least one cylinder unfilled; (f) sealing said manifold from said source of process material (g) depressurizing said manifold by flowing said process material into at least one of the unfilled cylinders connected to said manifold; and (h) disconnecting tile filled cylinders from said manifold.
