Abstract:
An injection system for injecting one or more additives into at least one pressurizable container for use in combination with a filling system, said filling system providing a flow of fluid from a tank of fluid to said at least one pressurizable container through a conduit, said injection system comprising:a delivery system adapted for transferring at least one additive from a source of said one or more additives to at least one portal; andsaid at least one portal operatively connected to said delivery system and said filling system, said portal comprising at least:a chamber defining an internal space having an upstream end and a downstream end relative to the flow of fluid provided by said filling system;a first valve having a first end connected to said upstream end of said chamber, a second end connected to said delivery system, and a third end connected to at least a portion of said conduit, said first valve having at least a first position and a second position, in said first position, said delivery system is in fluid communication with said chamber and said filling system is fluidly isolated from said chamber, in said second position, said delivery system is fluidly isolated from said chamber and said filling system is in fluid communication with said chamber; anda second valve having a first end connected to said downstream end of said chamber and a second end connected to a conduit which leads to said at least one pressurizable container, said second valve having an opened and closed position;when said first valve is in said first position and said second valve is closed, said portal has a first configuration in which said chamber is adapted to receive said one or more additives from said delivery system while being fluidly isolated from said filling system;when said first valve is in said second position and said second valve is opened, said portal has a second configuration in which said chamber is in fluid communication with said filling system while being fluidly isolated from said delivery system wherein the flow of fluid provided by said filling system enters said upstream end of said chamber and exits said downstream end of said chamber, thereby forcing said one or more additives deposited in said chamber to be carried into said at least one pressurizable container by the flow of fluid provided by said filling system.
