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).

Assessing Excipient Variability within QbD Drug Product Development

Oct 30, 2012
Joseph Kushner
Understanding variability in excipient physico-chemical properties is becoming an important aspect of Quality-by-Design (QbD) drug product development. However, present experimental methods are only able to study a few physico-chemical properties on a few excipient lots due to time, cost, and...

Thermal Reduction of Magnetically Stabilized Ferrites Under Reduced Pressure

Oct 30, 2012
Nicholas AuYeung
Oxidation of a metal (or metal oxide) by H 2 O and CO 2 followed by a regenerative high temperature thermal reduction of the resulting metal oxide is a promising method for using concentrated solar energy to produce syngas, a precursor for liquid fuels. For such a process to become viable, the...

The Role of PAT, Condition Monitoring and Adaptive Control in Delivering QbD

Oct 29, 2012
Steve Hammond
“The Role of PAT, Condition Monitoring and Adaptive Control in Delivering QbD” Stephen Hammond, Mark Smith, Pfizer Global Supply, Peapack NJ, USA The use of spectroscopic techniques such as NIR spectroscopy to deliver greater process understanding, either providing difficult to obtain compositional...

Modelling of a Filter Drying Process

Oct 29, 2012
Mark A. Pinto
Filter drying, also referred to as vacuum contact drying, is a process widely used in the pharmaceutical industry to remove water or organic solvents. The advantage of this process over other drying operations is that it can be used to dry solids that are sensitive to oxygen and temperature. The...

Exceptional Event Managemnt Applied to Continuous Pharmaceutical Manufacturing

Oct 29, 2012
Anshu Gupta
One of the important challenges in effective real time process management is the implementation of intelligent systems that can assist human operators in making supervisory control decisions, instead of simply sounding an alarm when process variables go out of range. Operator failures to exercise...

On the Selection of Ionic Liquids for the Conversion of Cellulosic Biomass Feedstock

Oct 29, 2012
Sameer Parvathikar
The use of ionic liquids (ILs) as solvents represents a promising route for the conversion of cellulosic biomass feedstock. 1,3-dialkylimidazolium ILs in particular, have become a popular and thoroughly-studied reaction media for this. Reactions such as the dissolution and hydrolysis of cellulose,...

Random Thoughts: Inspired by Rich Felder

Oct 29, 2012
Kenny Felder, Lisa G. Bullard, Rebecca Brent
This talk is part of the invited session 'Random Thoughts: Inspired by Rich Felder'. Description: This session honors Dr. Richard M. Felder, Hoechst Celanese Professor Emeritus of Chemical Engineering at North Carolina State University. Rich has been recognized for his sustained contributions to...

A Shell-and-Tube Direct Steam Generator for Concentrated Solar Power Generation

Oct 29, 2012
Theodore Wiesner
?Making Solar Energy Economical? is one of the Grand Challenges posed by the National Academy of Engineering. However, innovation in concentrating solar power technologies (CSP) lags by considerable margins that of all other renewable energy technologies. The levelized cost of electricity (LCOE)...

A Model-Based Approach for the Construction of Design Spaces in Quality-by-Design

Oct 29, 2012
Richard D. Braatz
This presentation considers the characterization of the set of allowable real parameter uncertainties for the output of a nonlinear system to be located in a prespecified target range. This word “parameter” is used by FDA and in this presentation to refer to any variable held at a fixed value...

Scientific Validation of THz Spectroscopic Measurement and Its Pharmaceutical Process Analytical Technology (PAT) Applications: Case Studies of First Principles Modeling Approach

Oct 29, 2012
Huiquan Wu
As an emerging technology, THz spectroscopy has gained increasing attention in the pharmaceutical area during the last decade. This attention is due to the fact that (1) it provides a promising alternative approach for in-depth understanding of both intermolecular interaction among pharmaceutical...
