Abstract
A supply system is disclosed for continuously supplying a liquid for in-plant use comprising a stationary liquid supply tank connected to an in-plant pumping or receiving system. The liquid supply tank is periodically refilled from a transport tank which is positioned on top of the supply tank and connected to the supply tank via a hose assembly connecting a bottom discharge in the transport tank to a top inlet in the supply tank. A sight tube is provided in the lower supply tank for visualizing the liquid level in the supply tank, and a vapor return tube is provided for removal of vapor from the supply tank to the transport tank as the transport tank contents are drained into the supply tank. Once the contents of the transport tank have been emptied into the supply tank, the transport tank is removed and returned to the liquid supplier for recycling. The supply tank is never completely emptied thereby enabling the flow of liquid to continue uninterruptedly for use in the plant.
