ControlSoft's MANTRA Advanced Process Control Applications

MANTRA for improving batch reactor heat transfer applications

This kind of application uses a traditional chemical reactor or autoclave chamber that is enclosed by a heating/cooling jacket. The chemical reaction, typically a batch operation, is heated or cooled according to the batch recipe. The reactor is heated and cooled by a circulating heat transfer medium that needs to operate within a wide range of temperatures to meet the requirements of each phase of the recipe.

Heat Transfer Difficulties

  • Each heating/cooling medium have different system dynamics, making difficult to tune the PID controller.
  • During a disturbance or setpoint change, each heating/cooling medium are used sequentially, which can delay a the control response.
  • When the control output moves between ranges, the differences between the heating/cooling mechanisms can cause instability of control and cycling between ranges.

Our Application Note AN316 explains how you can achieve fast and tight control of reactor jacket temperature at a wide range of setpoints by using three different heating/cooling media—while also minimizing costs and maximizing ease of use.

MANTRA for Bio Chemical Process Control

Requiring the knowledge of bioengineering, chemical engineering, fermentation engineering, enzyme engineering, and separation engineering, amino acid production is a good example of how a complex process can benefit from advanced control technology. ControlSoft's MANTRA advanced control system is used to control the complete process of amino acid production at a plant in Jiangxi, China.

ControlSoft's MANTRA's Advanced Process Control System is used to control the whole amino acid production process but particularly the temperatures and vacuum settings at desired levels to provide flexibility to meet different operating procedures. The goal of the MANTRA software is three-fold: reject any disturbances to the process, respond quickly to setpoint changes, and optimize the available controller outputs during steady-state control.

ControlSoft solutions featuring MANTRA APC technology can increase the profitability of your process.

  • Improve reaction and recovery in your application (better efficiency)
  • Improve product quality and consistency (higher percentage of on-spec product)
  • Reduce energy and material waste (save $$$)
  • Maintain your existing control system and wiring

ControlSoft advanced technology can improve your chemical reaction and recovery applications while saving time, effort, and money. To learn how, simply request a free copy of our application notes and the technical papers by selecting your choice(s) from the table below.

MANTRA for Dissolved Oxygen & Fermentation Control

Minimize waste of material and maximize quality of product by maintaining tight, responsive control of the interaction of the parameters of temperature, pressure, pH, and dissolved oxygen (DO2), which enables both anaerobes and organisms requiring high oxygen input to be grown.

ControlSoft's MANTRA's Coordinated Control (CC) function block is used to control dissolved oxygen content to desired levels. The goal of the CC block is three-fold: reject any disturbances to the process, respond quickly to setpoint changes, and optimize the available controller outputs during steady-state control.
