A Primer on Patent Law

    Chemical engineers, whether directly engaged in R&D or not, routinely deal with situations that are new and different, not only to them, but to those in the chemical process industries (CPI) as a whole. Quite often, the way…

Greenhouse Gases An Effective Strategy for Managing GHG Emissions

  Climate change has become an important strategic issue for many operating companies throughout the chemical process industries (CPI). Public interest is increasing,1 shareholder interest continues to mount,2 and climate policy discussions are actively taking place at the state, regional,…

VLE Calculations in Multicomponent Systems

    In multicomponent systems, equation-of-state (EOS) methods generally do a good job of determining vapor-phase properties. But accurate determination of properties for the liquid phase is much more difficult, especially when the liquid contains dissimilar molecules, polar molecules such…

Filtration in the spotlight

    In the chemical process industries (CPI), pressure is constantly on to improve filtration. The filtration step has to be performed quickly (time is money), efficiently (product loss is money lost), and effectively (energy costs for pumping and drying…

U.S. EPA Honors Green Chemistry

For the 12th straight year, the U.S. Environmental Protection Agency (EPA) has recognized efforts in developing less-toxic alternatives to existing technologies and reducing or eliminating waste in the manufacturing process. The 2007 Presidential Green Chemistry Challenge Awards, which are described…
