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.
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.
There is another side to toll processing. It involves the companies that arguably have the best possible know-how and hardware for the simple reason that they are the equipment manufacturers themselves, offering toll processing services that utilize their own products.
Automation systems have now reached such a high degree of reliability that many personnel at plants now take them for granted. Learn to use digital communication with your asset management tools to achieve predictive maintenance and substantial savings.
"Bad actor" pumps are those pumps that have trouble with frequent and repetitive failures. In many cases, the source of the problem is an ANSI pump trying valiantly to handle a liquid well beyond the range of its design rating.of 300 degs. F.
Residue curve mapping is a powerful tool to better understand the design and operation of distillation columns. This article describes how to use residue curve maps to check the feasibility of separation of homogeneous mixtures and for developing the conceptual design of towers.
British Petroleum's tragic March 2005 explosion has been well-documented through the press. Read here to find out how that tragedy spurred the development of a new program addressing management issues at BP.
