If the apparatus necessary for the process cannot be calculated with the simulation program, it is defined with own programs. Heat exchangers are calculated with the integrated software and made available to the design department.

With our software package we are able to calculate heat exchangers of all types and to optimize them constructively. In particular, the required exchange surface and design aspects such as the occurrence of vibrations are weighed against each other and the operating media and parameters are considered when dimensioning pipes and internals.

For precipitators and absorption columns we have developed our own programs based on our experience and empirical data, which take into account all hydraulic and process engineering aspects. After the basic dimensioning, internals are defined which are adapted to the process task and at the same time take maintenance aspects and costs into account.

Besides the new design of process plants and their components, existing plants can also be modelled with the simulation software. This model can then be used to investigate specific changes in operational parameters and modifications.

When debottlenecking or expanding the capacity of plants, the optimum adjustments can thus be determined, and the process-related effects quantified.

In decomplexing, the simulation model can be used to reliably predict the process-related effects of dismantling sub-systems or apparatus.

Thus, velocities in pipelines, pressure losses, blow-out quantities or expansion temperatures and pressures can be calculated e.g. in order to have a reliable basis for decisions on improvement measures in case of operational problems.

In the second step, the process engineering changes can then be calculated on the new heat, material and emission balances or the installation of additional equipment.

The results of the static investigations are forces, loads and moments in the system itself and at the interfaces to apparatus, machines, and steel structures. With this data, bearing concepts are developed and e.g. thermal expansion arcs are defined. Dynamic analysis can be used to determine the effects of pressure surges and vibrations and, as the overall result of the investigation, the entire piping system can be optimised.

By using the standardized interfaces of our 3D design programs, the calculation results are directly integrated in the design. They are the basis for the design of spring hangers and expansion joints or the development of special designs and ensure that the permissible stresses according to ASME or the relevant DIN EN regulations are complied with.

In branched networks with several feeders, branched piping systems and different design cases, we can use internationally recognized software tools to analyse the system, identify weak points and plan expansions.

During the simulation of possible operating conditions such as general incidents, fire, power failures, etc., the process engineering parameters (flow velocities, pressure losses, flow rates, temperatures and pressures) are determined and serve as a basis for the evaluation of existing systems and their adaptations.

If flares are installed and media fluids are burned during expansion processes, the simulation of the combustion processes not only enables the thermal characteristics to be determined, but also allows emissions to be predicted. These calculations are also used in the design of combustion plants of all kinds.
