  • Heat integration steps can present control problems

    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.

  • Fieldbus improves control system reliability

    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.

  • Energy savings are often disguised as problems

    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.
