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 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

The Integrated Gasification Combined Cycle (IGCC) is a promising technology for the future use of coal to provide energy. During this process, many of the trace elements present in coal are volatilized, and remain in the gas phase through the gas turbine, only to be released in the flue gas....Read more
Complimentary Theoretical and Experimental Studies: CO2 Capture with Supported Ionic Liquid Membrane
In order to capture the carbon content of coal, one option would be to gasify it with mixtures of, e.g. steam, CO2 and O2, to produce synthesis gas: the water-gas shift (WGS) reaction, CO + H2O <--> CO2 + H2, could then be used to increase the yield of hydrogen. In principle, if the WGS...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
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
Gas Technology Institute (GTI) and PoroGen Corporation are jointly developing a novel hybrid membrane – absorption process for pre- and post-combustion CO2 capture (Carbo-Lock™ process). The novel Carbo-Lock™ process combines advantageous features of both absorption and membrane processes to...Read more

This paper reports on recent results relating to high temperature sorption of metallic mercury on MinPlus sorbent, an inorganic substrate derived from paper recycling residues. Results from a packed bed reactor as well as in-flow dispersed phase reactor are reported. A new type of packed bed was...Read more
The Integrated Gasification Combined Cycle (IGCC) is a promising technology for the future use of coal to provide clean energy in a more efficient manner. During this process, many of the trace elements present in coal are volatilized, and remain in the gas phase through the gas turbine, only to...Read more
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

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
Global climate models indicate that acting rapidly to reduce carbon dioxide emissions will provide greater benefits to the environment than delaying action; however, new technologies, currently under development, may be significantly less costly than those currently ready to be deployed. This...Read more
Energy efficient capture of CO2 from coal-fired power plants is one of the grand challenges for the U.S. both to end dependence on imported energy and to reduce greenhouse gas emissions. Nalco Company and Argonne National Laboratory received a Department

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
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
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 power

In the carbon capture and sequestration (CCS )scenario, vapor liquid equilibrium (VLE) curves represent the theoretical relationship between local gaseous CO2 vapor pressure and the respective carbon loading in solution for a given operating temperature. It determines the maximum carbon content...Read more
Gasification of coal – a low-cost and abundant domestic feedstock – and subsequent conversion to hydrogen and energy with simultaneous CO2 capture can improve national energy security in an environmentally responsible manner. To fulfill the promise of clean energy production through gasification...Read more
We describe a new class of porous metal-adeninate crystalline materials. We describe the syntheses of these materials and discuss strategies for optimizing the capacity of these materials as selective sorbents for carbon dioxide. In particular, we describe how we can control the coordination...Read more
