Optimal heat exchange network synthesis for a heat and water recovery system with multiple flue gas streams of a petroleum refinery |
| 초록 |
Petroleum refinery is one of the major CO2 emitters in the global industry sector. Also it consumes a large amount of industrial water as feedstock for utility. In particular, for those located in the Middle East area which is arid, supply of the water resource turns out to be a serious problem, so it is highly demanded to utilize the water resource more efficiently. To reduce CO2 emission as well as water consumption, the heat and water recovery (HWR) system has been proposed for the steam plant of the petroleum refinery. The system allows recovering heat energy of hot flue gas streams to heat the condensate water through heat exchangers. Moreover, the flue gas streams are further cooled below the water dew point to obtain water. The goal of this study is to formulate and solve an optimization problem for the design of the HWR system. Transshipment model is applied for the HEN synthesis which affects the CO2 reduction ability of the system. The condition of flue gasses and an equation of water recovery rate according to the cooling temperature are obtained using commercial process simulators. The objective function is max profit and CO2 constraint are considered. |
