摘要

Supply of liquefied gases. The plant is characterized in that: *the withdrawal outlet is provided with a transfer pump ( 16 ) and with an ejector ( 17 ) which are located upstream of the fitting ( 11 ); *the ullage space of the container is equipped with a gas phase recycling line ( 5 ) equipped with a fitting ( 15 ); and * heat exchange means ( 19 ) are interposed in order to:-condense all or a portion of the recycled gas phase from the container and reinject it in liquid form into the ejector where any further condensation is completed,-vaporize a portion of the liquid phase from the tank in order to maintain the gas phase occupying the ullage space of the latter. Application to the filling of several containers by a mobile tank.
