Short Educational Video on Transfer Function Identification: Is it possible to visually identify second-order transfer function parameters?

Welcome to the fourth video from PiControl Solutions on practical Industrial System Identification and Process Control as we continue with a series of short, practical, and useful educational videos. Second-order processes on step tests react in two very original shapes: S-shape and a Wavy shape. But it is sometimes very difficult to distinguish it from […]

Best PID Tuning Optimization, APC And MPC Software Using Novel, New Technology

CNRL continues to use PiControl’s PITOPS PID tuning software for entire plant-wide application. PITOPS PID tuning software is integrated with APC design (advanced process control design) and MPC implementation techniques (model predictive control). The model improvement functionality uses the new and improved GRG optimization technique (generalized reduced gradient method of optimization) that proves to be […]

DCS-APC (Advanced Process Control) a better and superior option to MPC (Model Predictive Control) in olefins plants

In recent times, most olefins plants crack ethane that is more readily available than a few decades ago.  Olefins plants built during the 1970s to 1990s were often more complex.  The olefins plants were equipped with more complex furnace configuration than today.  The older olefins plant furnaces were designed for a lot of flexibility; they […]

Textbook APC (Advanced Process Control) for Urea Plant

Typically, urea is manufactured by reacting liquid ammonia and carbon in an autoclave, where ammonium carbamate is formed.  Ammonium carbamate is dehydrated in the synthesis reactor to molten urea.  The product is fed to vacuum evaporator for concentrating the slurry.  Slurry is dried in a prilling tower and passed from the top of the tower […]

Powerful DCS-based APC (Advanced Process Control) for Ammonia Production Plant

A typical modern ammonia-producing plant first converts natural gas, liquified petroleum gas, or petroleum naphtha into gaseous hydrogen. Starting with a feedstock heavy in methane as a main component. The initial step in the process is to add steam, and the mixture goes to two reformer reactors where hydrogen plus carbon monoxide is formed. Air […]
