摘要

Ory-coal combustion is one of the technical solutions for mitigating CO_2 in thermal power plants. Many processes have been evolved in past the decade to capture CO_2 from process industries. Researchers at the National Energy Technology Laboratory (NETL) have patented a process, integrated pollutant removal (IPR), that uses off the shelf technology to produce a sequestration-ready CO_2 stream from an oxy-combustion power plant. The IPR process as it is realized at the Jupiter Oxygen Burner Test Facility is a spray tower (direct-contact heat exchanger) followed by four stages of compression with intercooling. To study the energy flows of the oxy-combustion process, a IS MW_(th) oxy-combustion pulverized-coal-nred plant integrated with the IPR system was simulated and analyzed using ASPEN Plus and ASPEN energy analyzer. This paper discusses flue-gas recycle, energy flow, recovery, and optimization of IPR systems. ASPEN models of heat- and mass-transfer processes in a flue-gas-condensing heat-exchanger system were developed to predict the heat transferred from flue gas to cooling water. The flue-gas exit temperature, cooling water outlet temperature, and energy flows of IPR streams were computed using ASPEN models. Pinch principles are deployed for targeting design and operation-guiding purposes and balancing the heat and mass transfer in the IPR system. The results are expected to support sophistication of the IPR system design, improving its application in a variety of settings. They open the door for valuable IPR efficiency improvements and generalization of methodology for simultaneous management of energy resources.
