Boiler Steam Drum Level Control Strategies

Posted by Rohit Anantulwar on Jan 18, 2021 4:00:35 PM

Steam drum is a vital part of boiler system in chemical industries. proper and safe functioning of boiler depends on various parameters such as level of steam drum, flow of feedwater and flow of steam. The pressure, temperature and level of boiler system cannot be regulated directly but depends on the feed-water flow. The pressure or temperature in a boiler system can be maintained by controlling the flow of fuel and air whereas the level can be maintained by regulating the flow of feed water. The purpose of drum level controller is to keep the level at desired value, optimal interface level requires between steam and water within the steam drum. It is essential that the level of liquid must be low enough to assure that there is appropriate separation between steam and water and high enough to guarantee that the water exists in every steam generating tube. 

 

In this blog we will show the 3 most common drum level control schemes and what tuning strategy you should adopt for every strategy.

How LANXESS Belgium improves control with IPCOS process control tools

Posted by Christiaan Moons on Jan 18, 2021 12:13:13 PM

Leading specialty chemicals company, Lanxess Belgium, noticed the plant wasn’t working at its full potential. Many controllers were underperforming and in manual mode. Due to lack of time, the control engineers ran aground to complete optimization. A new approach was needed and Lanxess started using the IPCOS INCATools software: INCA PID tuner and INCA MPC. The first phase of tuning the PID controllers with INCA PID Tuner contributed to a
more stable plant and safer operations.

Read in this blog what benefits they gained by using the INCATools software, or download the case study to discover the process and results.

7 reasons to get INCATools PID Tuning software

Posted by Christiaan Moons on Jan 12, 2021 1:52:50 PM

When PID tuning it is done right, it can provide significant benefits to your plant. A little help from PID tuning software can help tremendously to get your tuning on track. You can find many free PID tuning software downloads on the internet, or you can find a free PID tuner in your DCS. Nevertheless, are numerous companies that provide PID software licences at a fair price. But, why would you pay for a PID tuning software licence when you can do somewhat the same with the free versions? 

The answer is simple, the most critical PID loops in your plant will get left behind when you use free PID tuning software. The freeware will stand in the way of optimization and receiving the full ROI of your plant.

PID control Equations: Do you know the difference?

Posted by Christiaan Moons on Jan 4, 2021 11:44:21 AM

The principle of PID is very simple. Three subsets (P, I, D) of one equation that each have their own task. Nevertheless, the PID formula in your DCS/PLC can have many forms. The most common equations are the series and parallel equation. In this blog we'll show you that it's extremely important to know the different formulas to tune your controller.

How PID tuning impacts furnace control in plants

Posted by Didac Recio on Dec 8, 2020 10:37:45 AM

What if you could increase your return on investment, safety, and overall plant efficiency with just one optimization? Furnace control is often disregarded as furnaces are considered as subunits that are not important to optimize. However, one cannot underestimate the impact of the furnace performance on the overall unit. In this blog, we'll explain what the consequences of bad furnace control are, what the results of optimization will be and how to tune your furnace correctly.

PID Derivative: Don’t be afraid of the D (in PID tuning)

Posted by Michiel Huizer on Nov 16, 2020 12:32:15 PM

Why and when use Derivative in PID control? The vast majority of PID controllers are tuned with Proportional and Integral action only, while in some cases controller performance could be improved by including the D-action. Read in this blog what derivative action is and what to expect of the webinar ‘Don’t be afraid of the D’.

Did you consider robustness in your PID tuning?

Posted by Michiel Huizer on Oct 2, 2020 12:24:48 PM

You've all probably been in a similar situation - you became aware of an underperforming PID loop, took immediate action, tuned the loop and at the end of the day the PID loop was still performing well. The next day the operator complains; the loop had been oscillating all night and is now in manual mode. The first thing you need to do is check the PID parameters and tune the loop again, the operator isn't happy, and neither are you. You could prevent this if you calculated the robustness of the controller. Learn in this blog how to consider robustness by looking at your PID parameters in your PID tuning.

PID monitoring in a cost-effective way

Posted by Christiaan Moons on Sep 21, 2020 12:05:01 PM

It’s no secret that well-tuned PID loops contribute to a stable and healthy plant. Once optimally tuned, only critical PID loops that cause too many alarms tend to be tuned again. Underperforming loops are often ignored. But if you frequently analyze all your PID loops you can enhance total efficiency, have less wear and tear, more overall stability, and fewer operator interventions. Read in this blog why it is essential to monitor your PID’s and how to perform monitoring most cost-effectively.
