Abstract:
1. A hazardous fluid transfer system for transferring fluid within a closed environment, the system comprising: a source storage container for carrying a hazardous liquid therein; a target storage container for receiving the hazardous liquid; a liquid conduit communicating between the source storage container and the target storage container for delivering a liquid therebetween; a vapor conduit communicating between the source storage container and the target storage container for delivering a vapor therebetween; a pump operable with the liquid conduit for pumping the liquid from the source storage container to the target storage container during actuation thereof; a flow sensor operable for monitoring flow in the liquid conduit; a first pressure sensor operable for monitoring pressure within the liquid conduit; a valve operable with the vapor conduit for controlling vapor flow therethrough; a second pressure sensor operable with the vapor conduit for monitoring pressure therein; a vapor accumulator operable with the vapor conduit between the valve and the source container for accumulating vapor therein during periods when the valve is in an open position and allowing the accumulated vapor therein to flow into the source container during periods when the valve is in a closed position; and a controller operable for receiving input signals from the sensors and automatically actuating the pump responsive thereto.
