AIChE Webinar
Oct 3, 2012
Jessica Gray

This webinar provides background on how water is used for drilling and hydraulic fracturing and includes a review of hydraulic fracturing fluid composition and flowback and produced water quantity and composition.

Institute for Sustainability (IfS)

IfS is an umbrella organization encompassing a broad spectrum of activities related to sustainability. It has three sub-entities: the Sustainable Engineering Forum (SEF), the Center for Sustainable Technology Practices (CSTP), and the Youth Council on Sustainability Science and Technology (YCOSST). It also provides oversight to the AIChE Sustainability Index (sm).

Environmental Division (ENV)

The ENV division provides relevant programs on current environmental topics and non-confidential information concerning all aspects of environmental activity. The division promotes publication of papers of interest to chemical engineers in environmental activities as well as coordinates the Institute’s activities with other related societies.

BIOCORE - On a Paradigm for the Design and Synthesis of Real-Life Biorefineries

Oct 19, 2011
Aikaterini D. Mountraki
As oil is a fast depleting resource (BP, 2010), much is expected by the production of biofuels as valid options to replace fossil-oil transportation fuels. Biorefineries are not an entirely new concept. Many of the traditional biomass conversion technologies such as the sugar and paper industries...

Cellobiose Hydrolysis Using Acid-Functionalized Nanoparticles

Oct 18, 2011
Leidy Peña
Mineral acids have been used effectively for the pretreatment of cellulosic biomass to improve sugar recovery and promote its conversion to ethanol; however, substantial capital investment is required to enable separation of the acid, and corrosion-resistant materials are necessary. Disposal and...

Beyond Water: Expanding the Spectrum of Efficient Large Scale Separations

Oct 18, 2011
William J. Koros
Innovations in membrane materials, structures, modules and system design have fundamentally changed the water purification industry over the past four decades. Revolutionary reductions by a full order of magnitude in energy consumption per unit of delivered product were achieved by substituting...

An Osmotic Membrane Dehumidifier

Oct 17, 2011
Arthur S. Kesten
OSMOTIC MEMBRANE DEHUMIDIFIER It has long been known that relying on a vapor compression system to cool air down to the dew point in order to dehumidify is expensive to build and uses far too much energy to operate. The ability to dehumidify independently of cooling provides substantial advantage,...

Thermochemical Hydrogen Production by Alkali Metal Oxides

Oct 16, 2011
Hiroki Miyaoka
In this work, we have focused a thermo chemical hydrogen production from water by using alkali metal oxides. This system consists of three step reactions. First one is H 2 generation by the reaction of hydroxide and metal 2MOH+2M→2M 2 O+H 2 (endothermic). From the oxide as the product of first...

Forward Osmosis: Potential Use In Desalination and Water Reuse

Oct 16, 2011
Ali Altaee
Abstract There has been a recurring interest in using Forward Osmosis (FO) process in water treatment and desalination. The recent advance in membrane technology has encouraged further investment in the process technology. Despite the promising results from pilot and bench scale experiments the...

The Destruction of Dioxins In Fly Ash by Using Gliding Arc In Tornado

Mar 14, 2011
Liang Yu
The characteristic of gliding arc in tornado was investigated under different experimental conditions and the destruction of PCDD/Fs (polychlorinated dibenzo-p-dioxins/polychlorinated dibenzofurans) in medical waste incinerator fly ash by using a dc gliding arc in tornado reactor was studied in the...

The Energy Challenge: Providing Sustainable Supplies to Meet Growing Demand

Mar 13, 2011
F. Emil Jacobs
As economies grow and living standards improve, the world faces a dual energy challenge: meeting the growing demand for energy while mitigating emissions and their impact on the environment. ExxonMobil believes that addressing this dual challenge requires an integrated set of solutions which...

Design Enhancements of a High Temperature, Ceramic Micro-Channel Heat Exchanger

Nov 9, 2010
Merrill Wilson
The recent developments in the energy and process industries have lead to more efficient, higher-temperature processes and compact equipment. By using small features such as micro-channels, pin fins or plate fins the length scale for which transport occurs is minimized and thus increases the heat...

A Compact Integrated Warm Syngas Overall Cleanup System

Nov 8, 2010
Liyu Li
Gasification of coal or biomass to syngas followed by catalytic synthesis of ammonia, hydrocarbons or oxygenates provides a feasible strategy to meet the increasing demand for fertilizers and transportation fuels. This syngas has many impurities, including As, Be, Cd, Cl, Cr, Hg, K, N, Na, P, Pb, S...
