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

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

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

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

Ron's Response:

Curiosity is the cornerstone of a problem-solving mindset. It’s about asking “why” at every opportunity—not just when something goes wrong but to understand the deeper principles at play. Simulation training nu

Ron's Response:

To answer this question let us approach this from three different perspectives. There are three powerful perspectives that form the foundation of this mindset:

1. Curiosity and Openness to Possibil

Greg's Response:

Temperature RTD sensors should use 4 wires and TC sensors should use extension wires of same material as sensor with length as short as possible to minim

Greg's Response:

Temperature is often the most important of the common measurements because it is an indicator of process stream composition and product quality. Temperature

Ron's Response:

Let us first look at a definition from Kumar Dey “Centrifugal compressor surge is a characteristic behavior of the compressor t

Greg's Response:

Lime feeders have a transportation delay that is proportional to the length of the feeder divided by its speed. This transportation delay may be several min

Ron's Response:

Whenever an incident occurs the investigators freeze time and slowly break down the sequence of events—viewing it from all perspectives. If only we co

Greg's Response:

A common misconception is that the slope of the titration curve and, therefore, the system sensitivity can be decreased by reagent dilution. Reagent di

Greg's Response:

If the reagent pipeline is partially filled or empty or a dip tube is backfilled with process fluid, the regent delivery delay becomes the biggest sour

Greg's Response:

For a reagent dose to be precise enough, the reagent’s logarithmic acid dissociation constant (pKa) should be close to the pH set point so that it tends to f

In the last pod we discussed how stress can impact performance and what are some of the physiological responses to stress.

Stick and slip generally occur together and have a common cause of friction in the actuator design, stem packing, and seating surfaces. Rotary valves with

Capt. Chesley “Sully” Sullenberger was quoted as saying that the moments before the emergency water landing of US Airways Flight 1549 were "the worst sickening, pit-o

Greg's Response:

Static mixer have noisy pH measurements. Signal filtering can help but a downstream volume is needed to provide smoothing of pH oscillations that can be large

Ron's Response:

Developing a simulator program involves a financial commitment and resources to be successful. This continues after the initial installation of the facility. One

Greg's Response:

pH systems are extremely sensitive to the vessel design. A poor design can make good pH control impossible in nearly all systems despite the use of the most adva
