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 […]

Adaptive Advanced Control in DCS or PLC

Advanced Process Control in Chemical Plants Advanced Process Control (APC) is now commonly used in most chemical plants. APC consists of math and logic algorithms that reside in a DCS or PLC or on a host computer. These algorithms monitor process variables and move the plant towards the direction of increasing profit. Benefits of APC […]

Does your process really need MPC (model predictive control)? Check out DCS-based APC (advanced process control) before you decide.

Beware of Model Predictive Control (MPC) and Distributed Control System (DCS) companies trying to sell you expensive software that you do not need. We live in a world full of products and services. Many products and services are good and fall in the win-win category where the customer needs them and the supplier provides them. […]
