The more energy prices rise, the more heat integration saves. However, heat integration steps can present complex control problems. Slip-ups in putting control systems in place can make operations nearly impossible. That certainly was the case at one unit using heat recovery.

Profibus-PA and Foundation Fieldbus both reduce cabling cost by sharing wiring among several field instruments. They also save money by reducing the number of instrument interface cards required to connect field instruments to the control system. However, they all save money by being able to use the same field transmitter for a wide range of measured variables.
When processes change and plants need to install any of several types of ultra-high-purity process gases, specifying an appropriate piping system is crucial. Learn about a sound system design that maximizes efficiency, purity and safety.
The compressed air industry is taking a step that will clear the air about the performance of its equipment. For the first time, many compressed air equipment manufacturers will submit their 50 hp to 200 hp lubricated rotary-screw compressors and 200 cfm to 1,000 cfm refrigerated air dryers to an independent laboratory for performance testing.
The new market realities of higher and rising energy costs as well as global pressures to reduce fossil fuel intensity have made energy management tracking much more valuable. Learn how to keep energy productivity programs from running out of gas in Peter Garforth's latest Energy Expert column.
Faster. Smaller. Smarter. Modular. All express the future of process analytics. And un-stoppable describes the ongoing migration of process analytical instruments to continuous, online, field-mounted use at chemical plants.
While fermentation-based syntheses were once reserved for producing high-value specialty chemicals and biopharmaceuticals, bioprocess routes now are gaining increasing attention for commodity products.

Carefully managing compressed air can save money. Compressed air is often overlooked in energy studies because many people do not fully understand compressed air equipment, their own system, or what it costs to produce compressed air power.

The Restrictions of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (the RoHS Directive) is part of a growing wave of European Union product-based regulations that will profoundly impact global and United States product standards and thus the chemical industry.
