Influence Of Aerosols During Amine-Based Co2 Capture: Evolution And Control, David Immanuel Arthur Dhanraj
Influence Of Aerosols During Amine-Based Co2 Capture: Evolution And Control, David Immanuel Arthur Dhanraj
McKelvey School of Engineering Theses & Dissertations
Driven by escalating concerns on global warming and climate change, significant efforts have recently been initiated to reduce atmospheric CO2 concentration. Power generation from fossil fuels is the largest source of anthropogenic CO2. The US government has incentivized carbon capture through Section 45Q Tax code, which provides US$50/tCO2 (per metric ton) of qualified carbon dioxide captured and sequestered, as tax credits. The cost for carbon capture, transport and sequestration is US$75 – 150/t CO2, with the state-of-the-art capture technology costing between US$20 – 100/t CO2. Amine based post-combustion CO2 capture is the most economic technology suited for large power plants. …

Role Of Submicrometer Particles In Advanced Technologies Of Carbon Capture, Zhichao Li
McKelvey School of Engineering Theses & Dissertations
Oxy-combustion and post-combustion carbon capture technologies are two of the most promising strategies for carbon capture and storage (CCS), which is a commonly accepted approach to address the challenge of climate change. Pressurized oxy-combustion has been actively studied due to its great potential to enhance the power plant energy efficiency by recovering latent heat from water vapor condensation without incurring additional gas compression cost. On the other hand, amine-based CO2 scrubbers have been demonstrated to have high removal efficiency of CO2 with the possibility to recycle amine solutions, which makes the technology a promising candidate for post-combustion carbon capture. Nonetheless, …

Process And Reactor Level Simulations Of Calcium Looping Combustion, Wei Dai
McKelvey School of Engineering Theses & Dissertations
Calcium looping (CaL) is a recent technology for carbon capture from coal fired power plants which consumes less energy than other approaches such as oxy-fuel. In the first part of this thesis, a system level model is developed in ASPEN PLUS to calculate the energy penalty of introducing Calcium looping in a coal fired power plant. Several simplifications and assumptions are made to model the Calcium looping process. The relationship between the energy penalty due to CaL and carbon capture efficiency is used to validate the process model for both pre-combustion CaL and post-combustion CaL; it agrees well with the …
