Alfa Laval AB (Lund, Sweden; has developed a new reactor system, called Alfa Laval Plate Reactors (trademarked as ART), which combines the high-heat-transfer capabilities of plate heat exchangers with the efficient mixing and reaction control typical of microreactors into a single unit. Because of the high heat and mass transfer achieved in the system, the working inventory of...

Continuously measure chlorine in water The Model TCL (photo, upper left) is a complete system for the measurement of total chlorine in water. Comprised of a sample conditioning system, an analyzer and a sensor, this system provides continuous measurement and was designed to minimize maintenance requirements and operating costs. The sample conditioning system continuously injects a solution of acetic acid...

    Typical process utilities include electricity, process steam, refrigerants, compressed air, cooling water, heated water, hot oil, process water, demineralized water, municipal water, and river, lake, or ocean water. For preliminary cost estimates, waste disposal cost can also be treated like a utility expense. Unlike capital, labor, and other expenses, utility prices do not correlate simply...

    It’s not a question of whether the world supply of fossil is going to run out; its just a question of when, says professor Colin Webb, head of the chemical engineering department at the University of Manchester (England), who was addressing several hundred delegates at a Thursday-afternoon colloquium on biorefineries last month at Dechema e.V (Frankfurt, Germany). That’s why most...

    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...

    While politicians and research institutes debate about a future hydrogen economy, plant contractors and industrial gas suppliers are working overtime to build bigger, more efficient hydrogen plants to meet the immediate demands. The fact is, there doesn’t seem to be enough H2 around to meet the growing demand for clean fuels and basic chemicals. This is the first time in the market...

    Immersion heaters are used in a wide variety of applications in the chemical process industries (CPI). Knowing which heater to specify for a particular application and how to maintain it can make a manufacturing process more cost-efficient. This article describes the types of immersion heaters available, explains how to select them and provides guidance on installing and using the heaters. As...

    In process engineering and design, thermodynamics theory is applied to real and complex chemical-process applications. Software design simulators, such as HYSYS, PROII and Aspen Plus, serve as powerful tools that simplify process thermodynamic calculations. They eliminate the need for the engineer to solve complex differential equations, and they allow the application of variety of property...

WOW Energy (see item above) has also developed a patented process that uses commercial, off-the shelf components to reduce the FG temperature to near ambient, while converting the extracted thermal energy into electricity. The cascading closed-loop cycle (CCLC) does this by using a hydrocarbon (propane) working...

      Although water and steam are the ideal media for heat transfer, there are often situations when other heat-transfer fluids are called upon to perform this function in the chemical process industries (CPI). Thus there are, at the very high-temperature end, various types of heat-transfer fluids, such as molten salts and even molten metals. At the lower end of the temperature scale we...
