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...

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...

Mixture Component Prediction Using Iterative Optimization Technology

Oct 30, 2012
Koji Muteki
Spectroscopy techniques such as near infrared (NIR), mid Infrared (MIR) and ultraviolet (UV) are commonly used to monitor various process operations such as blending, mixing and chemical reactions in pharmaceutical development. The calibration required for a quantitative measurement can be a labor-...
