Marcellus Shale Gas Wastewater Reuse and Recycle

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.

Green Design, Green Energy, and Sustainability

SEF Webinar
Jan 25, 2012
Urmila Diwekar

This webinar presents a systems analysis perspective that extends the traditional design framework to green design, green energy and industrial ecology leading to sustainability.

New Design for Advanced Zero Emission Power Plant Concept

Oct 18, 2011
Wei Chen
The most significant anthropogenic greenhouse gas is CO 2 , which arises mainly from the use of fossil fuels. A new technology called Advanced Zero Emission Power Plant (AZEP) targeting CO 2 capture and storage (CCS) is being developed. In the AZEP concept, CO 2 -diluted O 2 is used to combust the...

Comparison of Chemical and Biological Delignification of Cardboard

Oct 18, 2011
Estefania Isaza
Some processes aimed to biofuels production, use lignocellulosic wastes as feedstocks for fermentative conversion. If this is the case, pretreatment is required to make these resources fully digestible. Among a wide range of pretreatment options, this study focuses and compares oxidative-alkaline...

Reducing Process Complexity for Cellulosic Ethanol

Oct 18, 2011
L.O. Ingram
Much of the process complexity and high capital costs associate with cellulosic ethanol (dilute acid hydrolysis as a pretreatment and enzymatic saccharification of cellulose) results from side products such as furfural, acetate, and soluble lignin compounds that inhibit the biocatalysts. Inhibitor...

Biomimicry of the Fungal Consolidation of Biomass Pretreatment with Saccharification

Oct 18, 2011
Justin T. Kaffenberger
Efficient breakdown of ligno-cellulosic material prior to fermentation for bio-fuel production is a key step in optimizing bio-fuel production. Current industrial practice involves chemical pretreatment and acid or enzymatic saccharification to prepare ligno-cellulosic biomass for fermentation. The...

Pyrolytic Pathways to Advanced Biofuels

Oct 18, 2011
R. C. Brown
Pyrolysis is the thermal conversion of carbonaceous materials in the absence of molecular oxygen to liquids, solids and gases. In the most general sense, pyrolysis can occur in an inert or reducing atmosphere or within a solvent (including water); it can occur at atmospheric or elevated pressure;...
