Process Control Automation
Process Control is the automating (monitoring and controlling) of any type of industrial process, continuous or batch, and typically comprised of streams of gases, liquids, powders, slurries, or melts. Batch processing refers to products/materials produced in specific limited quantities such as pharmaceutical or food & beverage products. Continuous processing involves a steady stream of material or product as encountered in mining or wastewater treatment.
Process variables could involve chemical composition, heat, pressure, time, level, flow, concentration, or any combination thereof. Our objective in process automation is to help you maximize quality and productivity of your processes, while also paying attention to energy and raw material efficiency, always putting safety first. Our experience with process controls spans the full range of our focus industries and many types of raw materials.
Our goal with process control automation is to help you meet your plant-level objectives, which may include the following:
- Meeting product specifications
- Minimizing waste
- Minimizing environmental impact
- Minimizing energy use
- Maximizing productivity
- Maintaining consistency of the product/process
All of these are components of producing profits, and that is obviously critical to your business’s success.
Good process control system design requires first and foremost an understanding of the process itself. We must know the inputs, the expected output, and the specs for both. Knowing the process variables and their effects on the process set point, individually and collectively, is critical to applying the PID control design criteria, and all of the associated programming. And our breadth of experience in our focus industries provides us with that understanding and expertise.
Examples of processes we have experience with are as follows:
- Water and wastewater treatment
- Mineral processing
- Frac sand sizing and treatment
- Carpet dying
- Natural gas odorizing and pressurization
- Boilers/steam generation
