Solutions for a Sustainable Tomorrow

Jan 30, 2013
James Porter

This presentation focuses on the critical components of a truly sustainable operation . . . safety, environment, energy, capital management, and asset productivity.

Leadership Is Everyone’s Responsibility

Feb 20, 2013
Greg Shaffer

This webinar discusses the “hidden leadership” opportunities that are woven into everyday roles, how to recognize these opportunities and take advantage of them.

Emissions of Mercury and Other Air Toxics: Compliance Strategies for Coal Combustion

AIChE and A&WMA Web Forum
Jan 23, 2013
Bob Fraser, Constance Senior, Nick Hutson

What do you need to know about mercury, HCI, metals and other toxics control? This webinar will address technical and permitting issues from two perspectives: what is required (by Nick Hutson of USEPA) and what strategies could you adopt (by Bob Fraser of ERM).

Coupling Industrial Carbon Mineralisation and Ocean Alkalinity Enhancement

Oct 30, 2012
Phil Renforth
Coupling industrial carbon mineralisation and ocean alkalinity enhancement Introduction The ocean carbonate system has the potential to store ~10 2 - 10 3 billions of tonnes of CO 2 as a stable bicarbonate solution. Some propose that this system can be manipulated by the addition of oxide and...

Assessing Anhydrous Tertiary Alkanolamines for Gas Purifications

Oct 30, 2012
David J. Heldebrant
Assessing Anhydrous Tertiary Alkanolamines for Gas Purifications Paul M. Mathias, Kash Afshar, Satish Reddy, Arnold R. Smith, Rubin J. McDougal Louis V. Jasperson, Phillip K. Koech, Mark D. Bearden, Charles J. Freeman, David J. Heldebrant Anhydrous tertiary alkanolamines chemically react with CO 2...

Creep and Aging of Phbv-Natural Fiber Composites

Oct 30, 2012
Sabbie Miller
A biobased composite composed of poly(β-hydroxybutyrate)-co-(β-hydroxyvalerate) (PHBV) matrix and natural reinforcing fibers has a potential closed-loop life cycle as their constituents can potentially produce their own feedstock carbon upon anaerobic degradation to produce more polymer. These...

Insights From Glucose Pyrolysis for Cellulose Pyrolysis

Oct 30, 2012
Patrick J. Fahey
Experimental and predicted kinetics of glucose, the monomer of cellulose, provides quantitative and qualitative insights into the pyrolysis of cellulose. This finding is somewhat surprising, as the monomer does not have the β-1,4-glycosidic linkage between rings that is characteristic of cellulose...

Pressure Swing Adsoprtion: Design and Optimization for Pre-Combustion Carbon Capture

Oct 30, 2012
Alexander W. Dowling
Pressure Swing Adsorption (PSA) is an efficient method for gas separation, and is a potential candidate for carbon dioxide (CO 2 ) capture from power plants. However, few PSA cycles have been designed for this purpose and the optimization of PSA systems for CO 2 capture remains a very challenging...

CO2 Mineralization Using Reactive Species

Oct 30, 2012
Roe-Hoan Yoon
Abstract While geologic sequestration method may be used to store large volumes of CO 2 , it involves two distinct steps, i.e., capture and storage, with the former being a more costly step. Also, finding suitable storage sites, pumping supercritical CO 2 , safekeeping it underground, and handling...

Kinetic Modeling of Syngas Production From Bio-Oil Gasification

Oct 30, 2012
Fariba Seyedzadeh Khanshan
Gasification of bio-oil is a desirable process to produce syngas as a renewable resource with no net greenhouse gas emissions. Bio-oil is a mixture of hundreds of chemicals derived from fast pyrolysis of biomass. Production of syngas from bio-oil is usually a high pressure (26 bar) and high...

Microchannel Rapid Temperature Swing Adsorption of CO2 for Methane Production

Oct 30, 2012
Kriston Brooks
A rapid thermal swing adsorption system combined with Sabatier reactor was developed to demonstrate the applicability of a NASA microchannel Mars In Situ Propellant Production (ISPP) system. A thermal swing adsorption pump was designed to collect and compress CO 2 by rapidly temperature cycling...

Optimal Design of Transient Microreactor Experiments

Oct 30, 2012
Spencer D. Schaber
Development of synthetic routes for active pharmaceutical ingredient (API) synthesis is increasingly performed using microreactors, because their use can reduce experimental cost (both time and material use), make hazardous reactions safer, and enable more precise control [1,2]. While microreactor...

Dependence of Hydrogen Adsorption on the Structural Properties of Carbons

Oct 30, 2012
Ali Qajar
Dependence of Hydrogen Adsorption on the Structural Properties of Carbon; Deviation from Graphite: Good or Bad? Ali Qajar, Maryam Peer, Ramakrishnan Rajagopalan, Henry C Foley Abstract: Adsorption of hydrogen on a series of carbons with different structural properties is studied. PFA-derived carbon...

A Monte Carlo Approach for Estimating and Validating Contingencies for CCS

Oct 30, 2012
Paul Worhach
The AACE International recommended practice for estimating process and project contingencies provides a set of contingency factors to be applied to total process capital cost, as a function of process technology development and class of estimate. Process contingency ranges from 0 to 10 percent for...
