Evaluation of Organic Rankine Cycle Geothermal Power Plant and Considerations

Oct 19, 2011

Kirtipal Barse

The objective of this work is to evaluate the feasibility of an Organic Rankine Cycle (ORC) power plant to generate electricity from low flow rates of a geothermal resource (~875 gpm) at low temperatures (T~100°C). A model of ORC was developed using HYSYS process simulator. DOE’s Cost of Renewable...

Effects of Ammonia Substitution On Stability Limits and Emissions of Premixed Hydrogen/Air Flames

Oct 19, 2011

Dong Hyun Um

The potential of partial ammonia (NH 3 ) substitution to improve the safety of hydrogen (H 2 ) use was evaluated, using premixed NH 3 /H 2 /air flames at normal temperature and pressure generated on a tube type burner. The effects of NH 3 substitution on the stability limits and nitrogen oxide (NO...

Change of Structure of Corncob with Dilute Acid and Lime Pretreatment and a Potential Process for Xylose Co-Production of Cellulosic Ethanol

Oct 19, 2011

Jihong Li

Degree of polymerization (DP) of cellulose is considered an important factor to effect on the conversion of Lignocellulose. The higher DP of cellulose, the more difficult conversion of lignocellulose is. In this study, corncobs were pretreated with dilute acid process for production of xylose, and...

Effects of Reaction Conditions On the Acid-Catalyzed Hydrolysis of Miscanthus Dissolved In An Ionic Liquid

Oct 19, 2011

Sean J. Dee

Miscanthus, a perennial grass, is an attractive biofuel feedstock compared with corn and poplar due to its high energy yield per hectare and low agricultural inputs such as water and soil nutrients. Recent studies have shown the three primary components of miscanthus, cellulose, hemicellulose, and...

Simultaneous Extracellular Polymeric Substance (EPS) and Lipid Production by Activated Sludge Via Fermentation of Glucose

Oct 19, 2011

Patrisha J. Pham

The use of activated sludge microflora to convert sugars, derived from the hydrolysis of lignocellulose biomass, into lipids for biofuel production is of current research interest in our group. Lipid accumulation in this system has been enhanced by manipulating the carbon-nitrogen (C:N) ratio and...

Towards Developing Anaerobic Digestion Based Biorefinery – Research On Food Wastes As Feedstock

Oct 19, 2011

Shulin Chen

Anaerobic digestion (AD) is a proven technology for waste treatment. However, as the organic material becomes more valuable and being treated as resources, traditional AD process is no longer adequate. The Bioprocessing and Bioproduct Engineering Laboratory at Washington State University has been...

Active Species Concentration Effects On Performance for a Non-Aqueous All-Vanadium Redox Flow Battery

Oct 19, 2011

Aaron A. Shinkle

Redox flow batteries (RFBs) are being developed for large-scale energy storage, uninterruptable grid-independent power supplies and load-leveling systems for solar or wind power. Aqueous chemistries are used for all current commercial RFBs, therefore, cell potentials are limited to the stability...

Biofuels Manufacturing: From Feedstocks to Manufacturing and End-Product Quality Control

Oct 19, 2011

Jose Menezes

Biofuels quality is related to the inherent of feedstock materials (RMs) and operating conditions used in their production. However to be used as fuel in engines biofuels must meet certain specifications regulated by ASTM or EN standards regardless of the manufacturing processes and / or the type...

Physical Properties and Rheological Characteristics of Deasphalted Oil Produced From a Solvent Deasphalting Process

Oct 19, 2011

Jung Moo Lee

Because of conventional oil being-exhausted and its increasing price, the technologies to use unconventional oil and low value crude residues, which have not been fully exploited, are receiving more and more interest. Unconventional oil contains a lot of asphaltene which hinders utilizability of...
