Dr. M. J. Plodinec

There are large uncertainties in the climate change debate that reflect the absence of the engineering community.

Study of CaO Carbonation for CO2 Capture Process

Oct 18, 2011

Loïc Favergeon

Anthropogenic carbon dioxide (CO 2 ) emissions, major contributors to the greenhouse effect, are considered as the main cause of global warming. So, decrease of CO 2 emitted by large industrial combustion sources or power plants, is an important scientific goal. One of the approaches is based on CO...

A-Priori Estimation of Reactive Amino Acid Based Ionic Liquids for CO2 Absorption

Oct 18, 2011

Johannes Voelkl

The separation of CO 2 is an important topic in thermal separation science. The scrubbing of carbon dioxide from exhaust gases has gained more interest in the last years to reduce the emissions of green for counteracting global warming but is also an important process step in biogas upgrade to...

Imidazole and Imidazole-Amine Hybrid Solvents for CO2 Capture

Oct 18, 2011

Jason E. Bara

Imidazoles and imidazole-amine hybrids are unique classes of organic solvents that feature properties similar to aqueous amine solvents and ionic liquids (ILs), both of which have received a great deal of attention for CO2 capture applications. However, to date, the utility of the imidazole...

Kinetics of CO2 Absorption Into Aqueous Potassium Carbonate Solution Promoted by Carbonic Anhydrase Enzyme

Oct 18, 2011

Xinhuai Ye

A novel Integrated Vacuum Carbonate Absorption Process (IVCAP) for post-combustion CO 2 capture is being developed at the University of Illinois at Urbana-Champaign. A key technical aspect of this process is to employ a biocatalyst, carbonic anhydrase (CA) enzyme, to enhance the rates of CO 2...

Synthesis of Optimal Adsorptive Carbon Capture Processes

Oct 17, 2011

David C. Miller

Solid sorbent carbon capture systems have the potential to require significantly lower regeneration energy compared to aqueous monoethanol amine (MEA) systems. To date, the majority of work on solid sorbents has focused on developing the sorbent materials themselves. In order to advance these...

The Application of a Model Predictive Control-Based Approach to CO2 Capture Processes: Towards Operational Cost Minimisation

Oct 17, 2011

Alicia Arce

Amine-based chemisorption of CO 2 is a promising near term option for the decarbonisation of large, fixed-point CO 2 emission sources [1] . However, the operational expenditure (OPEX) associated with this technology imposes a significant energy penalty on the power plant. As it is the solvent which...

Completing the Cycle: Capturing Gaseous Waste Carbon As Fuel/Chemicals

Oct 17, 2011

Michael A. Schultz

The world currently faces an enormous energy challenge. LanzaTech responds to this challenge by capturing and beneficially reusing waste carbon to make low carbon fuels and chemicals. The International Energy Outlook, in its 2010 reference case, projects that world primary energy consumption will...

A Methodology for Risk Assessment of CO2 Sequestration Based On Surrogate Models of Detailed Simulations

Oct 17, 2011

Yan Zhang

Large scale implementation of CO2 geologic sequestration requires detailed uncertainty analysis and risk assessment for leakage potential. Probabilistic risk assessment based on Monte Carlo simulation is one option for quantifying the risk. It involves repeated random realizations of a simulator to...

Development of An Integrated CO2 Capture, Transportation and Storage Infrastructure for the UK and North Sea Using An Optimisation Framework

Oct 16, 2011

N.V.S.N. Murthy Konda

Carbon Capture and Storage (CCS) is widely regarded as an effective medium-term CO 2 abatement technology. However, high cost of the capture technologies, at their current state of the art, and the huge upfront costs of the CO 2 transport pipelines and storage facilities are hindering the large-...

CO2 Chemical Absorption Based on Self-Heat Recuperation Technology for Pre-Combustion Process

Mar 15, 2011

Akira Kishimoto

Coal has performed an important role as the primary energy source since the industrial era in the eighteenth century. Recently, the importance of coal has been growing in the world. In fact, IEO2010 reports that energy consumption of coal is growing from 132 quadrillion Btu to 206 in 2035. The...

Investigation of the Adsorbed Species of CO2 on Mg(OH)2

Mar 15, 2011

James C. Fisher

Introduction Fossil fuels supply a majority of the world's energy needs. However, the combustion of fossil fuels is one of the major sources of the greenhouse gas CO 2 . Integrated gasification combined cycle (IGCC) is one the most efficient power generation systems that use coal. However, because...

The Role of Heat Exchangers In Post-Combustion CO2 Capture

Mar 14, 2011

Warren H. Ziegler

The role of heat exchangers in post-combustion CO2 capture Warren Ziegler Motivation: The overall energy penalty for post-combustion carbon capture by aqueous amines as well as solid sorbent systems can be reduced significantly by recovering heat from the lean/hot solvents coming out of the...
