Abstract
A recovery system includes a special organic Rankine cycle (SORC) system, an internal combustion system, a nitrogen generator and a gas-liquid separator. The SORC system includes a first stage heat exchanger (first HE), a plurality of second stage heat exchangers (second HE), a third stage heat exchanger (third HE), a turbo-expander, and at least one condenser. A recovery method, conducted in the recovery system, includes vaporizing a refrigerant, introducing the vaporized refrigerant to the turbo-expander to generate electricity, condensing the vaporized refrigerant in the at least one condenser, collecting nitrogen from the flue gas feed in the nitrogen generator, and collecting water from the flue gas feed in the gas-liquid separator. The refrigerant is vaporized by introducing the refrigerant through the first HE, second HE and third HE sequentially, and the flue gas feed through the third HE, second HE and first HE sequentially.
