Cement Degradation Under Conditions Relevant to Geological Carbon Sequestration

Nov 1, 2012

Leopold Brunet

Assessing the potential risks of CO 2 leakage from deep subsurface is one of the major challenges for geological carbon sequestration. Injected CO 2 can dissolve into in situ brine to produce acidity for cement wellbore degradation. This degradation can potentially change the properties of the...

Enzymatic Recovery of Polyhydroxybutyrate (PHB) From Bukerholderia Cepacia by Pancreatin

Nov 1, 2012

Yuanzhen Wang

Polyhydroxyalkanoates (PHAs) are a family of polyesters synthesized by many kinds of bacteria as intracellular carbon and energy storage compounds. PHAs have similar physical properties as currently used plastics,, but they can be degraded completely into water and carbon dioxide by natural...

Assessing the Role of Thermal Stresses in Caprock Integrity During CO2 Storage

Nov 1, 2012

Gennady Gor

Deep saline aquifers provide unbeatable capacities for long term CO 2 storage, provided CO 2 does not leak. Upon CO 2 injection the pressure in the aquifer increases and induces stresses in the caprock. If CO 2 is injected at the temperature different from the ambient temperature in the aquifer,...

Bench-Scale Electrochemical Production of Synthesis Gas

Nov 1, 2012

Tedd Lister

Syn-gas is a very useful mixture of H 2 and CO that can be utilized to synthesize a great variety of commodity chemicals and transportation fuels using established methods. Conventional methods create syn-gas using fossil resources which releases carbon into the atmosphere. Electrochemistry offers...

Influence of Impeller Design On Power Input and Performance During High Solid Enzymatic Hydrolysis of Pretreated Lignocellulose

Nov 1, 2012

Benny Palmqvist

Reaching high ethanol titers after the fermentation step is crucial in cellulosic ethanol production in order to make the process cost competitive and commercially available. To achieve this, a high amount of water insoluble solids (WIS), i.e. lignocellulose fibers, is needed in the hydrolysis step...

Critical Quality Attributes (CQAs) of Biodegradable Polymer Matrices and Particles: Impact of a Recent Mathematical Model

Nov 1, 2012

Sam N. Rothstein

Long-acting controlled release formulations address the top causes of non-compliance, a problem responsible for 10% of hospitalizations and over $100 billion in avoidable annual medical expenses. These formulation are also among the most difficult and costly formulations to design and produce...

Nov 1, 2012

Naresh Pavurala

On the Modeling of Oral Drug Delivery Naresh Pavurala, Luke E.K Achenie Department of Chemical Engineering, Virginia Polytechnic Institute and State University, Blacksburg, Virginia 24060 The oral administration route is by far the most common way of administering pharmacological substances. It is...

Numerical Simulation of Reservoir-Wellbore Fluid Flow Simulations At Geologic CO2 Sequestration Sites: Coupled or De-Coupled?

Nov 1, 2012

Rajesh Pawar

Leakage of CO 2 and brine through pre-existing wellbores is considered to be one of the main potential risks at geologic CO 2 sequestration sites. To assess impacts of this potential weakness, it is critical to accurately estimate leakage rates through failed wellbores. Currently, there is very...
