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

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-...

A Novel QbD Tool for Statistical Data Analysis

Oct 30, 2012
Linas Mockus
One of cornerstones of Quality by Design (QbD) is Design of Experiments (DoE). However, in addition to DoE, ICH Q8 (R2) recommends an enhanced approach to product and process development which is based on mechanistic first principle models. Such predictive models require parameters such as kinetic...

NETL CO2 Injection and Storage Cost Model

Oct 30, 2012
Tim Grant
The U.S. Department of Energy’s National Energy Technology Laboratory (NETL) has developed a model to estimate the costs of storing captured CO 2 . This model includes the range of costs from initial regional geologic evaluation through site characterization, permitting, injection/MVA operations,...

Variable Selection in Multivariate Modeling of Drug Product Formula and Process

Oct 30, 2012
Yong Cui
Multivariate data analysis methods such as partial least square (PLS) modeling have been increasingly applied to product development, particularly in the quality-by design paradigm. This study applied the PLS modeling to analyze a product development dataset combining a design of experiment study...

Vision-Based Solar Irradiation Prediction for the Control of Solar-Thermal Reactors

Oct 30, 2012
Elizabeth Saade Saade
One of the biggest challenges that solar thermochemical processes face is dealing with the intermittent nature of solar irradiation. Changes in solar irradiation directly affect the performance of solar-thermal reactors causing unnecessary shutdowns and start-ups, complications in the purification...
