MEA-based CO2 capture integrated with natural gas combined cycle or pulverized coal power plants: Operability and controllability through integrated design and control

摘要: Abstract Post-combustion solvent-based carbon capture is a promising technology that potentially can offset the greenhouse gas emissions from fossil-driven power generation systems. The challenge CO2 absorption (similar to other CCS technologies) imposes energetic penalties, and constrains operational flexibility. In this paper, we build upon our recent contributions in field (Sharifzadeh et al., 2016; Sharifzadeh Shah, 2016), study dynamic response of such process electricity load changes plant. key research question investigate if steady-state integrated design control framework applied previous studies, also ensure controllability under wide range disturbances. present considers mutual interactions between plant process. Other features interest include implications decisions as reboiler temperature, solvent circulation flow rate, concentration rate change or setpoint tracking for flexible operation. results suggest exhibits high degree flexibility could be enabler commercialization post-combustion capture.
