1. A system for regenerating a wash solution utilized to remove gaseous contaminants from a gas stream, the system comprising:
a regenerator; a first portion of a used wash solution provided to the regenerator at a first location; a first heat exchanger for heat transfer between a regenerated wash solution and a second portion of the used wash solution to form a first portion of a first heated used wash solution, wherein the first portion of the first heated used wash solution is provided at a second location; a second heat exchanger for heat transfer between the regenerated wash solution and a second portion of the first heated used wash solution to form a second heated used wash solution, wherein the second heated used wash solution is provided to the regenerator at a third location; and wherein the second heated used wash solution has a temperature greater than the first portion of the first heated used wash solution and the first portion of the first heated used wash solution has a temperature greater than the first portion of the used wash solution.
