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,...

Rule of Thumb for Reactor Design and Process Condition for Biodiesel Production

Oct 16, 2011
Masato Kouzu
The rule of thumb for reactor design and process condition for biodiesel production is introduced. The important aspect includes type of feedstock oil, catalyst selection, methanol/oil ratio, quality of the produced biodiesel. When low quality plant oil is used as the feedstock, its pre-treatment...

Future Fuels and Chemicals: Grand Challenges and Opportunities

Apr 2, 2012
To insure a Sustainable Future, CO 2 emissions must be reduced despite strong future growth in demand. “Easy oil” from conventional production will be less abundant, though coal and natural gas, as well as unconventional hydrocarbon reserves will remain in strong supply for decades to come. Carbon...

Chemical Engineering Careers (focus on environmental consulting)

Mar 14, 2011
Kurt Rindfusz
The profession of chemical engineering offers multiple, distinct career paths. Although many young professionals entering the professional world will spend the majority of their time in an industrial setting, working in important careers such as process engineering; many alternatives present...

Evaluation of Reverse Osmosis - Electrode-ionization Pilot Project in PT Badak NGL

Apr 4, 2012
Fany Arfianto
PT Badak NGL utilizes groundwater for Plants and Community water consumption. Demineralization water production in PT Badak NGL uses ion exchange process which has high safety risk since it utilizes sulfuric acid and caustic for ion exchanger regeneration. The sulfuric acid sometimes leaks out from...

Stripper Configurations for CO2 Capture by Aqueous Amines

Mar 23, 2010
David H. Van Wagener
A monumental task for improving the feasibility of carbon capture from the flue gas of coal-fired power plants is reducing the total energy cost. A generic absorption/stripping process using an aqueous amine solvent would reduce the net power production of a coal-fired power plant by roughly 30%,...

Microreactor for Industrial Application: Technical and Economical Benefits

Nov 8, 2010
Sergio Pissavini
A glass based high throughput microreactor technology is presented illustrating the basic design window, technical data and configuration. An overview of some class of reactions performance is provided as compared to batch process. For three typical reaction a comparison between typical plant...

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...

On the Solubility of Mercury in Liquid Hydrocarbons

Mar 21, 2010
D. Gallup
The solubility of Hgo was determined in 34 pure hydrocarbons, hydrocarbon mixtures, crude oils, and water from -65oC to +65oC (where each solvent remained liquid). The solubility of HgCl2 was also quantified, but in a limited subset of the solvents. The solubility of any Hg species in its...

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;...

Wood Pellets Self-Heating During Storage

Oct 17, 2011
Wendi Guo
Accidental fires in wood pellets silos happen frequently in the last five years. Experiments were carried out in this work at temperature range of 100 o C to 200 o C to study wood pellets chemical oxidation process. A self-heating model was developed to simulate the self-heating process using the...
