Steam Turbines Offer a Green Solution

While the Pennant ECS can be put to multiple applications, multi-bagger benefits accrue with its ability to convert both saturated and superheated steam into clean electrical energy. Typically, the ECS is used in parallel with a Pressure Reducing Valve (PRV)…

Scaleup is planned for a process that yields a fuel oil substitute from low-rank coals

  Silverado Green Fuel, Inc. (Vancouver BC, Canada; edlinks.chemengonline.com/6900-533) has entered into a memorandum of understanding with the Mississippi Development Authority (Jackson) to build a demonstration plant in Choctaw County to produce a clean-burning “green” liquid fuel from the state’s…

Food processing aid

The U.S. Dept. of Agriculture (Washington, D.C.) has launched a new Internet resource to help smaller companies answer food-safety questions and help food processors make science-based food-production decisions. Available at www.ars.usda.gov/naa/errc/mfsru/portal, the portal is said to be one of the…

This hydrotreating process saves hydrogen, catalyst and energy

DuPont (Wilmington, Del.; edlinks.chemengonline.com/6900-531) has acquired hydrotreating technology for desulfurizing motor fuels and hydrocracking intermediate refinery streams from Process Dynamics, Inc. (Fayetteville, Ark.). The IsoTherming Hydroprocessing Technology differs from other hydrotreating processes in that hydrogen is dissolved in the liquid…

This new diesel engine boosts fuel efficiency, slashes PM and NOx emissions
