Abstract

A method and apparatus for recycling streams in a separations process comprising: determining a measured reading of a parameter of the separations processor is in a suboptimal range; separating, via a separation unit having a volume of contact fluid, the inert gas from the pollutant gas in the inlet flue gas stream to form a clean gas stream and a purified pollutant gas stream; removing at least 1% of the volume of contact fluid to form a removed volume of contact liquid; performing some unit operations on the removed volume of contact fluid; injecting the clean gas stream into the inlet flue gas stream to form a flue gas stream of lower pollutant concentration; and, repeating at progressively lower pollutant concentration, as the inlet stream until the processor determines that a measured reading of the parameter has been returned to a substantially optimal range.
