FEBRUARY 2018 – THE IMPORTANCE OF ‘GOOD DATA’ WHEN TUNING PID LOOPS
Ask technicians and engineers about manually tuning PIDs. Their responses usually fall into one of the three different groups: 1) Some who will say it’s a “dark art” and won’t…
FEBRUARY 2018 – THINK YOU’VE GOT A LOT OF DATA? THINK AGAIN!
This article explores the data requirements that allow plant-wide monitoring and diagnostic technologies to accurately characterize changes in performance. In particular, it examines the requirements of key performance indices (KPIs)…
JULY 2017 – PROCESS OPTIMISATION: BIG DATA SHINES LIGHT ON CONTROLLER PERFORMANCE
An engineer working at a corn milling production plant receives his daily report on specific opportunities to optimize the facility’s regulatory control systems. The facility is one of dozens owned…
AUGUST 2016 – OVERCOMING LOOP TUNING CHALLENGES
For years, it was nessesary to steady a process before tuning software could be applied successfully. Because most industrial processes exhibit some degree of ocvillatory behavior, the steady-state tuning requirement…
AUGUST 2016 – HOW TO TUNE PID LOOPS: TEMPERATURE CONTROL CHALLENGES
Temperature control applications can be broken into two main categories—fully continuous and semi-continuous (or batch). An example of a fully continuous temperature controller is a shell-and-tube heat exchanger. In this…
JUNE 2016 – CLPM: DELIVERING ON THE PROMISE OF PLANT-WIDE OPTIMIZATION
Petrochemical manufacturers experience unique challenges when it comes to maintaining effective regulatory control. As practitioners know, the dynamics of petrochemical processes are complex. From the volatility of batch reactions and…
