Modular Dams for Reduced LCOE Low Head Hydropower

Modular Dams for Reduced LCOE Low Head Hydropower

Modular Dams for Hydropower U.S. Department of Energy (DOE) sponsored studies show that new stream reach hydropower potential in the U.S. is about 460 TWh/yr., but most of the available sites have environmental and social sustainability challenges that can be partly addressed by run-of-river (ROR) projects, which are considered environmentally friendly because of the modest impoundment and the requirement that the flow upstream of the project is matched by the flow downstream. One of the major ...

Passing the Torch: Alden Names New Gas Flow Systems Engineering Director

Holden, MA | November 8, 2016 Alden Research Laboratory, Inc. (Alden) of Holden, Mass., has announced that it has named David White Director of Gas Flow Systems Engineering (GFSE).  Mr. White has worked at Alden for 13 years, where he has been a leader in project management, modeling and analysis. The GFSE group grew out of an Alden acquisition in 2001, when Accentech in Cambridge, Mass. sold its DynaFlow group to Alden.  The group was focused primarily on optimization of air polluti...

Scale-up of a Biopharmaceutical Chromatography Column

Scale-up of a Biopharmaceutical Chromatography Column

A great many drug production processes rely on chromatography, which is a method used for separating chemical components – in this case monoclonal antibodies – which are a specific class of proteins used throughout the pharmaceutical industry.  Chromatography works by passing liquid from a cell culture (analyte, or mobile phase) through a column (see Figure 1).  The column is typically packed with small porous particles (media, or stationary phase) that have more affinity f...

Improved Air Pollutant Removal at Genesee Generating Station

Improved Air Pollutant Removal at Genesee Generating Station

Genesee Generating Station is a coal fired station jointly owned by Capital Power  and TransAlta , located near Genesee, Alberta, Canada, about eighty kilometers southwest of Edmonton. Two Spray Dryer Absorbers (SDA) on Unit 3 are designed to remove Sulfur Dioxide from the flue gas stream.  Atomizers eject droplets of lime slurry, which evaporate while the solid particulates react with the Sulfur Dioxide in the flue gas to form Calcium Sulfate, which is then captured in a downstream fa...

Flying Sturgeon? EPRI and Alden Evaluate the Passage of an Ancient Fish through The Whooshh Fish Cannon

Flying Sturgeon? EPRI and Alden Evaluate the Passage of an Ancient Fish through The Whooshh Fish Cannon

What happens when a fish that was swimming in our rivers at the same time dinosaurs were roaming the earth meets a fish passage technology developed within the last several years?  The answer is successful transport of an ancient species through a semi-rigid tube that uses a pressure differential to push fish from one end to the other.  This tube is known as the Whooshh fish transport system (also referred to as a salmon or fish cannon) developed by Whooshh Innovations of Washington St...
