Greg's Response:

Dynamic simulations running faster than real time are key to ensuring the best column temperature controller tuning. Except for high purity

Ron's Response:

Post-Traumatic Stress and PTSD can deeply affect an individual’s ability to perform safely and effectively in the workplace. Here are some key areas where PTS can have a profound impact:

1. Impaired Decision-Making...

Russ' Response:

Test means to review the model predictions (output values) with both data and logical expectations.  If your model outputs adequately match the process data and expectations over a wide range of operating conditions, then you

Dynamic simulations running faster than real time are key to ensuring the best column temperature control strategy. The manipulation of separ

Ron's Response:

Have you ever wondered why gaining the cooperation of operators can be difficult when introducing new procedures or control system changes? You might feel like you're being interrogated in a high-pressure environment. The truth

Russ' Response:

Here are eight steps in developing a dynamic model. Details and examples can be accessed under the Modeling/Simulation menu on my web site, www.r3eda.com.

1. Inventory - Decide the inventory that

Greg's Response:

Dynamic simulations can be help ensure distillation column pressure does not cause instability from operation at the weep point or flood point. The opera

Ron's Response:

Recognizing the symptoms of PTSD early is essential for taking action and finding support. PTSD can deeply affect many aspects of life, and if left untreated, it can lead to complications like depression, substance abuse, and ev

Russ' Response:

Earlier I shared that I typically classify models as empirical or phenomenological.

In phenomenological models, the mathematical functions are grounded in a mechanistic relation. These models could be termed rigoro

Greg's Response:

Batch-operated stirred cooling crystallizers are the most common type in the industry, but they tend to yield poor quality, primarily due to the high cooling

Ron's Response:

While PTSD is often linked to severe injuries or loss of life, I will address both PTSD and PTS, focusing on the often overlooked mental health challenges that can arise from less severe but still traumatic

Russ' Response:

I would broadly classify models as empirical or phenomenological.  

Empirical models are developed by matching flexible mathematical functions to data.  The functions might be neural networks, or classic statistical power

Julie's Response:

Many years ago, one site had an incident where an interruption in the flow of an organic fuel led to a deflagration. As a result, the operators always r

Greg's Response:

The basic loop arrangement for dryer temperature control would use cascade control of outlet temperature to set inlet temperature. However, a constant outlet temper

Russ' Response:

I would broadly classify models as empirical or phenomenological.

Empirical models are developed by matching flexible mathematical functions to data.  The functions migh

Greg's Response:

In kilns and calciners, there are typically four zones. First is a drying zone of constant temperature, followed by a heating zone of rising temperature

Ron's Response:

In high-pressure situations, even the best technical knowledge is of little use without focus and the ability to manage stress effectively. Simulation training helps operators develop these essential sk

Julie's Response:

Back in 2019, the new DuPont was formed after the merger and split with Dow. Many sites were struggling to continue their migration proje

Greg's Response:

A vessel is defined here as storage, recycle, blend, or surge volume where there is no heat of reaction and no agitator. Fortunately, most vessel volumes are so la

Ron's Response:

Pattern recognition and tacit knowledge—the instincts gained through experience—are indispensable for problem-solving. But how do you cultivate these skills in a controlled environment? Simulation trai

Russ' Response:

Traditionally, process design uses steady state (SS) simulation, and it serves its purpose well.  Most analysis of processes and textbook instruction on how processes work use SS r

Greg's Response:

Flows much lower than design causes a high process gain and high process deadtime that can lead to temperature oscillations and possible instability. Low v
