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).
Claims20
A production plant, comprising:
- a primary-process system including a furnace which combusts fuel to further production of electrical power by heating water/steam in a primary-process fluid line which conveys the water/steam through a closed turbine cycle operably connected to a main generator, a stack through which flue gas exits the production plant, an exhaust line extending from the furnace to the stack, and a scrubber which introduces water into the exhaust line;
- and
- an energy-recovery system including an energy-recovery fluid line for conveying a medium and a heat exchanger placing the energy-recovery fluid line in heat-transfer relationship with the exhaust line downstream of the scrubber.
A production plant comprising:
- a primary-process system including a furnace which combusts fuel to further production of a primary product, a stack through which flue gas exits the production plant, an exhaust line extending from the furnace to the stack, and a scrubber which introduces water into the exhaust line, and
- an energy-recovery system including a fluid line for conveying a medium and a heat exchanger placing the fluid line in heat-transfer relationship with the exhaust line downstream of the scrubber;
- wherein the scrubber causes pollutant particles within the flue gas to be captured in liquid droplets and/or pollutant gasses within the flue gas to be dissolved or absorbed into the liquid;
- and
- wherein the flue gas exiting the scrubber is at water-saturation conditions.
