Flexible dynamic operation of solar-integrated power plant with solvent based post-combustion carbon capture (PCC) process

摘要: This paper examines flexible operation of solvent-based post-combustion carbon capture (PCC) for the reduction power plant emissions while minimizing revenue loss due to reduced electricity output. The study is conducted using a model superstructure enveloping three plants; plant, PCC and solar thermal field where are operated flexibly under influence hourly market weather conditions. Reduced (surrogate) models reboiler duty auxiliary requirement generated applied simulate compare four cases, (A) with PCC, (B) assisted (C) repowering – variable net output (D) fixed Such analyses dynamic conditions including part-load varying rate optimize plant. Each case was simulated lower price $25/tonne-CO2 higher $50/tonne-CO2. comparison cases B–D found that optimal generation C can be up 42% than solar-assisted (case B). Case most profitable lowest intensity exhibit constant both prices.
