Even Multi-product Plants can be simulated

On these evaluation data, the analysis and optimization of the simulated processes is based. To spare the engineers laborious calculating, Process Edition provides a number of helpful tools, including optimization, statistical analysis, or an interface for thermodynamical databases.

As a consequence not only single processes can be described, but the simulation model can even be extended to multi-product plants. To support the users in modeling, even consulting in process engineering is provided by the company’s in-house branch.

Simulation of Separation Processes

While Inosim software is specialized in an overall plant design and optimization, the Prosim software used in the cooperation focuses on the action going on within single units of the simulated plant. Prosim Batch Column is special software for the simulation of the processing behavior of a batch distillation.

This process includes complex phenomena which make it nearly impossible to optimize the separation process without the help of simulation. Separating azeotropics or describing reactive or extractive distillations are some examples for complex phenomena which are difficult to handle.

For the simulation of the distillation process, Prosim Batch Column offers:

• A rigorous dynamic model that is configurable

• Detailed modeling of the heating system, hydrodynamics of the column condenser/decanter and associated controls

• Optimization of the most complex separation processes (azeotropic, extractive, reactive, …)

To test the integration of Prosim Batch Column with the Inosim Process Edition, as a case example a distillation of toluol from a toluol-acetonitrol-methanol-water mixture was chosen. At first, a model with a seven-step distillation protocol was implemented by using the Prosim software.

In correspondence to the Prosim simulation, the Inosim software emulated the same procedure in a production recipe. For that recipe, Process Edition’s newly featured recipe module for batch distillation was applied.

Instead of default mass and energy balances on the levels of black box and shortcut, this special module contained an interface connecting both tools.

Via this interface, the Prosim model was initialized, the simulation was triggered off, and, for the single steps of the batch distillation chain, their process durations, heating steam consumptions and the distillate’s amount and composition were transferred to Process Edition fully automatic.

Resulting from the interface, now the Inosim simulation tool possessed all data which were necessary to generate a component balance and a Gantt chart of the processes and material transfers involved.
