Process control is essential for ensuring the safety, efficiency, and quality of chemical plant operations. However, designing a robust process control system can be challenging, as it involves ...

Troubleshooting a process control system using a diagram requires careful consideration. First, one must define the problem, collecting data such as values and statuses of input/output variables ...

Each multi-stage pressure reduction system has a unique design objective tailored to its process control requirements. For instance, in slurry transport pipelines within the mining industry, the goal ...

The precise flow control is very much dependent on detection of the flow rate and how accurately the system can move the pneumatic actuators. With 16-bit accuracy lending each step size 0.005° ...

QUESTION: I have designed a three-element control system for a boiler of 45 Kg/cm2, 40 TPH, used in a sugar factory. The problem is large fluctuations in steam flow of the boiler. I want to set the ...

Robert Ard is director of applications engineering at Valmet (www.valmet.com), a developer and supplier of process technologies, automation and services for the pulp, paper, energy, marine and other ...

The Type 8750 can store the flow leakage curve of each rotary valve so that for any given inlet pressure the 8750 knows how much additional air is required to compensate for the air lost from the ...

System identification plays an important role in system control and controller tuning. Data-driven identification provides a behavioristic model of an identified system or process that can be useful ...

Quick read. Flow Meter Design: Orifice type flow meters measure gas flow based on pressure drops, requiring accurate design conditions for molecular weight, pressure, and temperature to ensure correct ...

Process operators that embrace this new approach to SIS can realize new efficiencies in their operations and transform how they manage process safety. Here’s how. Easing equipment configuration and ...

Ratio feedforward. Feedforward control monitors variables that are known to disturb the process and will take action when these change. These are known as disturbance variables (DV). Figure 2 shows ...
