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...

Azotobacter are nitrogen-fixing bacteria that do a useful job in soil by converting N 2 to ammonia. As a side reaction they also produce hydrogen, most of which they oxidize for their own energy consumption. In a project of the U.S. Dept. of Agriculture’s Soybean and Nitrogen Fixation Unit (USDA; www.ars.usda.gov) and North Carolina State University (Raleigh, N.C.), scientists have...

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...

Apilot plant that uses pressure swing adsorption (PSA) to extract helium from natural gas has been started up and is operating successfully in India at the Kuthalam Gas Collecting Station of Oil and Natural Gas Corp. (ONGC; www.ongcindia.com). Normally, helium is obtained by liquefaction of all the other components in natural gas, but this is economically impractical for the Kuthalam gas, which contains...

Fluorite, the natural mineral of calcium fluoride, is a key feedstock for making fluorochemicals. In Japan, however, the cost and availability of fluorite has become problematic due to recent restrictions on its import from China. To alleviate the problem, Organo Corp. (Tokyo, Japan; www.organo.co.jp) has developed a process that recovers CaF2 from wastewater containing high (1 – 9%) concentrations...
