  Large reductions in the emission of pollutants have been reported in the operation of a novel type of municipal solid-waste treatment plant. A group from the Hong Kong University of Science and Technology’s Dept. of Chemical Engineering ( has reported test results recently conducted on a municipal-solid-waste (MSW), co-combustion pilot plant — a novel design...

    The process industries are extensive users of energy. But it is now clearly established that a large amount of this energy is wasted, essentially in the form of heat rejected to the environment through gaseous or liquid effluents. The temperature level of this heat makes it of no use by the process; and at the same time, in many cases, it cannot be economically upgraded. Examples of...

    Provided that they are updated when appropriate to keep them relevant, time-tested heuristics rules based upon experience, also referred to as rules of thumb, can be useful for the design, specifying and operation of several kinds of equipment used in process plants. The first and foremost heuristic rule is that the engineer should not shy away from using heuristics - and the second rule is...

This month, JFE Steel Corp. (Tokyo, Japan; started up a new production plant that produces 100 m.t./yr of solar-grade (SOG) silicon (Si) from crude Si metal. The company also started to design a 500-1,000-m.t./yr plant for making SOG Si, and plans to start operations by March 2008. Up to now, JFE Steel used directional-solidification (DS), which aligns the Si...

      Biomass has come center stage in the pursuit of reduced dependence on finite - not to mention geopolitically sensitive - quantities of fossil fuels such as petroleum, coal and natural gas. And while ethanol produced from corn is one promising path for biomass, it is by no means the only one. The number of known viable raw materials is vast, and the assortment of feasible downstream...

Researchers at Kanagawa University (Yokohama, Japan; have developed a three-phase emulsification technology for making stable emulsions of diesel-fuel oil in water. Tests with the emulsion (involving a 30-ton truck) show that fuel-combustion efficiency is increased by 10-15% compared to conventional diesel fuel, and the emissions of dust and nitrogen oxides are reduced by 95 and...

Brown coal accounts for about half the world’s coal reserves. Although it contains less ash and sulfur than bituminous, brown coal contains more water, which reduces its heating value. To take advantage of this “greener” source of fuel, Kobe Steel Ltd. (Tokyo; has developed the upgraded brown coal (UBC) process, which increases the heat value of standard brown...

    Heat transfer takes place in every plant in the chemical process industries (CPI), and in a significant proportion of individual equipment items. And of the many varieties of heat exchanger, shell-and-tube versions must surely be the most traditional. Doyle & Roth Mfg. Co. Inc. (New York) has been serving the process industries since 1932, and supplies a full range of shell-and-tube...
