Abstract
Impure steam is partially cooled on a first side of an energy transfer dee, forming a condensate substantially free of CO.sub.2 and other non-condensible gases. The condensate is separated from the impure steam and accumulated in a separator/accumulator. The condensate stream is conveyed through a control valve back to a second side of the energy transfer device for reheating to steam substantially free of CO.sub.2 and other non-condensible gases.
Claims2
A method for removing CO.sub.2 and other non-condensible gases from steam, comprising the steps of:
- a) cooling a portion of impure feed steam to form a pure liquid condensate;
- then
- b) separating the pure liquid condensate from the impure feed steam;
- then
- c) accumulating said pure liquid condensate;
- then
- d) controlling the flow rate of said pure liquid condensate;
- then
- e) reheating said pure liquid condensate to form steam free of CO.sub.2 and other non-condensible gases.
