Efficiency (Energy)

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...

Optimal Charge Rates for a Lithium Ion Cell Saeed Khaleghi Rahimian, Sean Rayman, Ralph E. White Department of Chemical Engineering, University of South Carolina, Columbia, SC29208, USA Abstract The optimum charge rate for a lithium ion cell at each cycle is determined to maximize the useful life...

Glycerol is a viable renewable feedstock that has emerged as a consequence of triglyceride conversion to biodiesel. In addition to glycerol conversion to commodity chemicals such as propylene glycol and epichlorohydrin, formation of higher-value specialty chemical products such as 1,3-...

A novel Integrated Vacuum Carbonate Absorption Process (IVCAP) for post-combustion CO 2 capture is being developed at the University of Illinois at Urbana-Champaign. A key technical aspect of this process is to employ a biocatalyst, carbonic anhydrase (CA) enzyme, to enhance the rates of CO 2...

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...

Three classes of nonfouling substances, poly[poly(ethylene glycol) methyl ether methacrylate] (POEM), poly(sulfobetaine methacrylate) (PSBMA), and perfluoroalkyl tagged poly(ethylene glycol) surfactants (fPEG), were covalently tethered onto the surface of Anopore TM membranes (nominal pore size 0.2...

The University of Kentucky, Center for Applied Energy Research is investigating oxygen carriers (OC) for chemical looping combustion (CLC) with the goal of developing a pressurized chemical looping combustion/gasification process for generating electricity from coal. An important issue in the...

A milestone in process safety was the 1974 Flixborough explosion in the United Kingdom the caused twenty-eight deaths. Following, the accident interest in chemical process industry safety increasd, as well as from government regulatory organizations and the general public. Since 1978, interest in...
