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) or Pressure Reducing Desuperheater Station (PRDS) situated downstream of the boiler. The ECS, configured in the above arrangement is able to smartly...

Global Resource Corp. (GRC; West Berlin, N.J.; edlinks.che.com/6897-534) is commercializing a technology that converts auto shredder residue (ASR) into combustible gases, liquid fuels and scrap metal using microwaves. The use of microwaves to achieve this goal has been attempted in the past, but GRC is one of the first to succeed at an economically viable level, says GRC’s chief engineer Hawk Hogan. Unil...

Polylactic acid (PLA) is a commercially available biodegradable polymer used in many nonfood products as an alternative to petrochemical-derived polymers. However, PLA's physical properties limit its use in many applications. Scientists at the USDA’s Eastern Regional Research Center (ERRC; Wyndmoor, Penn....

            Many coal-fired power plants make gypsum and construction materials. But they should also consider manufacturing hydrochloric acid and ethanol. Furthermore, they should consider substituting biomass and waste organics for up to 10% of the coal. The combination of these initiatives would make coal plants much “greener.” Coal is the cost effective way to...

The rise of the salty water table in many areas of Australia is threatening a large area of agricultural land. In a two-year research, development and demonstration project, scientists have been looking for ways to solve the problem by producing fresh water as a valuable byproduct of salinity mitigation. The Renewable Energy Group of RMIT University's School of Aerospace, Mechanical and Manufacturing...

    For companies in the chemical process industries, water is an indispensable utility. But the growing scarcity of quality industrial water, combined with stricter environmental regulations and the rising cost of wastewater treatment, have encouraged the conservation of water as a key utility in process plants. Concurrently, the development of systematic techniques for water reduction has made...

      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...

Most of today's solar cells are made from silicon wafers cut from blocks of crystals. The wafers are typically 0.2-0.25-mm thick, yet most of the photon-to-electricity conversion takes place in the outermost 0.02 mm of the wafer. In an effort to reduce the amount of Si required (and thus the cost) for solar cells, BP Solar (Frederick, Md; edlinks.che.com/6517-538) is supporting a three-year research...

    Solvents have been used for centuries and in all type of industries for the processing, manufacturing and formulation of goods. In the chemical process industries (CPI), solvents are used in various process-operation steps such as separation (of gas, liquid and/or solid), reaction (as reaction medium, reactant, and carrier), degreasing, washing and many more. As part of product formulations...

    Fuel costs rose sharply in 2005 because of hurricane damage to U.S. interests in the Gulf of Mexico, and international developments in the oil supply market. Competing fuels — coal and natural gas — rose in price in lockstep. Natural gas has risen in cost, and has been reported to be as much as $17/MM Btu in December 2005 for industrial use in the northeastern U.S. As operating...
