PCS 7 Unit Template "Polymerization Reactor" using the example of the Chemical Industry

  • Entry
  • Associated product(s)
The "Polymerization Reactor" unit template is based on a standardized and structured design of the automation program through the use of predefined equipment and the control modules. The example is used both as a basis for projects and as an overall standardization in the form of templates.

Introduction
The standardization of automation engineering for processing plants, such as in the chemical industry, is a major challenge. Different process steps and procedures, different equipment and flexibility in the production make the task even more difficult. This includes the configuring of the plant according to the physical model of the ISA 106 standard. This specifies the lower four levels, i.e. plant, unit, technical facility and control module. A plant always consists of units. The units can, in turn, comprise plant units which can be automated by equipment modules.

A polymerization reactor is an integral part of many chemical processes. Polymerization reactors can be designed for continuous as well as discontinuous operation with different volumes. The selection of a specific reactor is based on typical specifications which include:

  • Production volume and polymer formation
  • Reaction rates, aggregate states of monomers, comonomers and polymers
  • Viscosity, thermal stability

This application example contains a polymerization reactor with circulation cooling for continuous operation.

During the manufacturing process of polymers, the monomer, comonomer, hydrogen reactants as well as the catalyst and cocatalyst, among others, are added and stirred in the reactor. The use of an MPC control (Model Predictive Control), improves the quality of the manufacturing process or the product.

The unit template "Polymerization Reactor" provides a template that comprises all typical components, their open- and closed-loop control, the necessary logic and interlocking as well as the visualization. It is modularly structured and based on standardized equipment modules and process tag types.

Its utilization offers the following advantages:

  • A reduction of the knowledge necessary to develop applications
  • A decrease in the configuration effort
  • More flexible setup and adaptation due to equipment modules
  • Standardized structures
