Carbon Capture and Storage (CCS) is widely regarded as an effective medium-term CO2 abatement technology. However, high cost of the capture technologies, at their current state of the art, and the huge upfront costs of the CO2 transport pipelines and...Read more
Anthropogenic carbon dioxide (CO2) emissions, major contributors to the greenhouse effect, are considered as the main cause of global warming. So, decrease of CO2 emitted by large industrial combustion sources or power plants, is an important...Read more
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...Read more
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...Read more

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...Read more
The nation is facing a renaissance in energy technology to include dramatic changes in transportation, electricity production, distribution and use, and energy efficiency. The nation is also rapidly expanding its scientific capabilities and is currently leading the world in areas such as...Read more
Absolute and per-capita energy consumption is bound to increase globally, leading to a projected increase in energy requirements of 50% by 2020. The primary source for providing a majority of the energy will continue to be fossil fuels. However, an array of enabling technologies needs to be...Read more
In this work, we will report a new liquid/inorganic membrane product concept for CO2 separation. A liquid fluid of selective CO2 absorption properties is immobilized in a thin, inorganic substrate sheet (20~50um) of graded pore structures. CO2 selectively absorbs into the liquid fluid in the...Read more
A monumental task for improving the feasibility of carbon capture from the flue gas of coal-fired power plants is reducing the total energy cost. A generic absorption/stripping process using an aqueous amine solvent would reduce the net power production of a coal-fired power plant by roughly 30...Read more
We will discuss a history of Industrial gas usage and how they helped shape the fuels and petrochemicals Industries. A look at the ftutre of IG in F&PD will also be presented.Read more
The increase of atmospheric carbon dioxide concentrations in recent years is well documented. Its potential link to an earth wide greenhouse-like effect has led recently to tighter regulations on carbon dioxide emissions from various industrial sources. One of the most common emitters is the...Read more
The climate implications of emerging technologies that capture CO2 to produce transportation fuels (CCTF) are investigated by studying two examples: biodiesel from microalgae and Sandia National Laboratory’s S2P process. Simple performance and economic models for each...Read more
Modeling Mercury Chemistry in Coal-Fired Air Preheaters: Effects of Sulfur Trioxide and Surface Area
Mercury emissions from coal-fired power plants are a concern to both the state and federal governments in the U.S. US EPA had proposed to regulate mercury emissions from coal-fired power plants using the Clean Air Mercury Rule (CAMR). This two-phase program allowed trading of mercury...Read more
Production of power from coal inevitably generates carbon dioxide (CO2) as a by-product. To mitigate global climate change, this CO2 must be captured and sequestered. With current technologies, separating CO2 from flue gas accounts for about 70% of the total cost for CO2 capture and...Read more
Secondary Effects of Reducing Carbon Dioxide Emissions
While climate change has lost some interest to the global economy, the United States and the World continue to move forward on advancing research and technologies to capture, sequester, or reuse the green house gas carbon

Carbon dioxide is the major product from coal combustion and is released into the air and causes global climate warming which we are facing today. Current technologies for capturing CO2 including solvent-based (amines) and CaO-based materials are still too energy intensive. Hence, there is...Read more
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
Improved solvent reaction kinetics and carbon capacity continue to be a major research interest for the scrubbing of CO2 in post-combustion processes. The DOE has set a new target for post-combustion CO2 capture of less than a 35% increase in the cost of electricity, while capturing at least 90...Read more
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 CO2. Integrated gasification combined cycle (IGCC) is one the most efficient
