Although ammonia is still made by the near-century-old Haber-Bosch process, today’s ammonia plants bear little resemblance to those early units — now literally decorating the lawns outside BASF in Ludwigshafen, and Dechema in Frankfurt, Germany. For one thing, the efficiencies of this energy-intensive, brute-force reaction of hydrogen and nitrogen have increased dramatically, especially...

A method for identifying less-expensive catalysts, compared to commercial, precious-metal-based ones, is starting to deliver results by researchers at the Center for Atomic-scale Materials Design, Dept. of Physics, Technical University of Denmark (CAMD; Lyngby; www.camd.dtu.dk) and their collaborators. The computer-aided method ultimately generates a plot of cost-of-metal versus heat of adsorption for the...

The Lawrence Berkeley National Laboratory (LBL; Berkeley, Calif.; www.lbl.gov) has developed a new xenobiotics bioremediation system that can be used to treat contaminated soil and water. Whereas conventional bioelectrical remediation methods rely on the addition of chemicals to provide electron donors or acceptors to stimulate the remediative organism’s metabolic process, LBL’s system uses an...

Since the original invention of the steady-stream eyewash over 50 years ago, the accepted practice in the chemical process industries (CPI) and other industrial circles has been to flush the eyes with two, separate, arc-shaped water streams, each one flowing from the outside corner of the eye inward (diagram). A little-known, but potentially serious problem with this approach, says Michael Markovsky, vice...

Liberty Engineering (Hamburg, N.Y.; www.libertypsa.com) has developed a bioremediation system that fully removes carcinogens from soil in 90 days. The process is based on microbial oxidation of organic compounds by petrophyllic pseudonomads in an oxygen-rich environment. The bacteria are specifically isolated for their affinity to metabolize heavy hydrocarbons, aromatic compounds and organic solvents...

Last month, what is claimed as the first pilot plant in the world to demonstrate carbon-dioxide capture and storage (CCS) based on oxy-combustion came onstream next to Vattenfall´s 1,600-MW, lignite-fired Schwarze Pumpe power plant in Germany. The 30-MW pulverized-coal demonstration...

Algae constitutes roughly half of the Earth’s photosynthetic activity and undergirds the food chain for approximately 70% of the world’s biomass. With over 100,000 strains ranging from microscopic single-cellular organisms to seaweed species miles in length, algae would seem to hold almost unlimited potential for biochemical engineering and bio-refining applications. Though they have formed a...

Accuracy and reliability, ease of use, the ability to handle special materials and compactness are all factors to consider when purchasing weighing, proportioning and feeding equipment for use in the chemical process industries (CPI). Because each CPI application differs, there’s a host of new technologies available to suit a variety of needs. Presented here is a round up of the latest developments...
