Abstract
A method of introducing flue gas, from a flue stack in a steam-assisted production facility, into a heat exchanger. The flue gas comprises boiler combustion products selected from at least one of commercial pipeline gas and produced gas. The method begins by cooling a portion of the water vapor in the flue gas in the heat exchanger to produce flue gas water. This flue gas water is then collected and removed as make-up water.
