Chemicals: Facilitating Decision-Making with Data

Mechanical issues can often go undetected for long periods of time, all the while negatively affecting a facility’s production throughput and efficiency. Although the responsibility of engineering staff is to root out and resolve such mechanical problems, they sometimes require multiple forms of proof before accepting the presence of poor process behavior.

Are Slow Cycle Times Eating Your Profits?

Although not a financial services company, Evonik Industries fully appreciates the time value of money. That’s especially true in terms of how the company manages the cycle time of its batch processes. A long cycle time often corresponds with erratic control. Evonik sees an opportunity for improvement through leveraging Control Station’s LOOPPRO PID tuning technologies to improve control and to strengthen bottom-line financial performance.

Is Your Advanced Control Full of Hot Air?

In the highly competitive world of process manufacturing even the cost of steam can be an important financial consideration. Although only a source of low-density energy, waste steam is virtually free as it’s collected from other industrial processes across the production environment. Compared to the typical cost of steam production, waste steam comes at a fraction of the cost of producing intermediate steam and can prove a valuable contributor to profitable plant operations.

Who Should Use Feed Forward Control? What applications are best for Feed Forward?

It’s not uncommon for process control discussions to focus on use of the PID to improve a loop’s ability to track Set Point. Oftentimes tweaks to controller tuning parameters either seek incremental reduction in Settling Time or strive to limit Overshoot. Indeed, many PID tuning courses position optimization of a control loop’s Set Point Tracking as the ultimate goal. Such a bias overlooks the value of other strategies like Feed Forward Control.
