Claim 0:
1. A system for removal of a flux in a gas stream, the system comprising:
a scrubber chamber having a gas inlet through which the gas stream is introduced into the scrubber chamber, and a gas outlet through which the gas stream is withdrawn from the scrubber chamber;
at least one rinse agent delivery mechanism for introducing a rinse agent into the scrubber chamber for contact with the gas stream;
a condenser portion of the scrubber chamber for receiving the gas stream at a temperature for condensing a second portion of the flux in the gas stream;
a condensed flux removal apparatus adapted for removal from the scrubber chamber of at least a portion of the rinse agent and the flux which has condensed;
wherein the condensed flux removal apparatus comprises a first liquid collector comprising:
a tank having a first compartment and a second compartment and a wall separating the first compartment and the second compartment defining a weir at an upper end of the wall;
wherein the first compartment is operative to contain a liquid containing the rinse agent and the flux received from the scrubber chamber, the liquid over a time period being separated into a flux phase disposed in an upper layer of the first compartment and a rinse agent phase disposed in a lower layer of the first compartment;
a rinse supply apparatus for introducing the rinse agent into the first compartment in an amount sufficient to cause the flux phase to flow over the weir from the first compartment into the second compartment; and
a flux waste removal apparatus for removing the flux phase from the second compartment; and

wherein the condensed flux removal apparatus comprises a second liquid collector comprising:
a valve system selectively coupled to the first liquid collector and the second liquid collector such that the first and the second liquid collectors are alternately coupled to the scrubber chamber to collect the rinse agent and the flux, while the other of the liquid collectors is decoupled from the scrubber chamber to permit removal of the flux phase from the second compartment of the decoupled flux collector.
