Hydrocarbon leaks can disrupt recirculated cooling-water systems. Here’s an outline of effects and remedies Water is often the fluid of choice for cooling systems in the chemical process industries (CPI). Recirculated cooling-water systems are used to control the temperature of process fluids, which is necessary for process control and to achieve target product yields and specifications. Hydrocarbon...

Daihatsu Motor Co., Ltd. (Osaka, Japan; edlinks.che.com/7369-532) has designed a fuel cell for powering automobiles, using nickel and cobalt for the electrodes (instead of conventional platinum and carbon), and hydrazine hydrate (N 2H4. H2O) as its fuel (instead of hydrogen). Although hydrazine is a hazardous material, the company says the hazard level is about the same as gasoline. And unlike H2, which...

Traditionally, the cogeneration of steam and electricity has been restricted to plants that generate superheated steam, making the recovery of energy losses from saturated steam impossible for many industrial sites ranging from distilleries to pharmaceutical plants and pulp-and-paper mills. At the Chem Show (see first item above), Pennant International Corp. (Edison, N.J.; edlinks.che.com/6902-538)...

The amount of crude oil remaining in depleted oil fields has been estimated to be about 50 – 80% of the total estimated oil reserves. In the past, CO2 has been injected into such wells for enhanced-oil recovery — a technique that displaces the oil and stores the greenhouse gas. Now, a completely different approach to monetizing the carbon is being considered by Inpex Holdings Inc. (Tokyo...

In Malaysia, the raw material for biodiesel production has been palm oil. However, making biodiesel can conflict with the oil’s use as food, and growing palm oil (even for food) has caused the destruction of tropical forests in Borneo, Sumatra and other regions. A team from the Dept. of Chem. Eng. at the Universiti Teknologi Petronas, (Perak, Malaysia...

As the price of electricity, natural gas and other fossil fuels continues to climb, chemical processors are more closely examining high-temperature operations and heat-transfer systems to see if more efficiency can be had. In many cases it can, and, as a result, heat-transfer projects are not only justifiable, but downright attractive. "Traditionally we used to see chemical processors looking at their...
