Abstract

A production plant comprises a primary-process system (10) and an energy-recovery system (100). The energy-recovery system (100) includes a fluid line (110) for conveying a medium and a heat exchanger (120) placing the fluid line (110) in heat-transfer relationship with an exhaust line (40) upstream of a scrubber (70). The heat exchanger (120) causes condensation of water vapor within the exhaust line (40) and transfers heat to the medium within the fluid line (110).
