ASPEN PLUS® / HYSYS®
ACCE + OPTIPLANT 3D

Advanced Process Modelling, Optimization and Engineering Solutions

At P&P Industries AG, we combine in-depth process engineering expertise with advanced simulation and engineering tools such as Aspen Plus®, Aspen HYSYS®, Aspen Capital Cost Estimator (ACCE), and OptiPlant 3D.

Our engineering approach goes beyond process simulation. We develop realistic process models, evaluate design alternatives and translate complex calculations into practical engineering solutions, optimized plant concepts and reliable investment decisions.

Whether for an existing plant, a revamp or a new project, our focus is clear: improve process performance, reduce technical risk and identify economically attractive solutions.

Aspen Plus & Aspen HYSYS Process Simulation

From Process Models to Practical Engineering Decisions

We use Aspen Plus and Aspen HYSYS process simulation to model individual process units as well as complete industrial processes.

Depending on the application, our process modelling and simulation services can help answer key engineering questions:

How can plant efficiency and process performance be improved?
How will a process modification affect the overall plant?
What are the optimal operating conditions?
Where are the process bottlenecks?
Which design alternative provides the best technical and economic solution?
How will changes influence energy consumption, OPEX and CAPEX?

Our objective is not simply to deliver a simulation model. We turn simulation results into clear engineering conclusions and actionable recommendations.

Process Optimization & Plant Performance Studies

Improve Efficiency, Capacity and Operating Performance

Process simulation provides a powerful basis for evaluating new operating scenarios and identifying optimization potential.

P&P supports clients with:

  • Process optimization and debottlenecking
  • Operating scenario analysis
  • Mass and energy balance development
  • Vapor-liquid equilibrium calculations
  • Energy optimization
  • Process modification and revamp studies
  • Equipment performance evaluation
  • Technical comparison of alternative process concepts

This allows potential improvements to be evaluated before modifications are implemented in the actual plant.

Feasibility Studies & CAPEX Estimation

Technical and Economic Evaluation from an Early Project Stage

A technically attractive solution must also make economic sense.

By combining process engineering and process simulation with Aspen Capital Cost Estimator (ACCE) and OptiPlant 3D, P&P can support the technical and economic evaluation of project alternatives.

Our services can include:

  • Early-stage project evaluation
  • Feasibility and FEL studies
  • CAPEX estimation
  • Evaluation of major project cost drivers
  • Comparison of alternative plant concepts
  • Process equipment sizing
  • Preliminary plant layout development
  • Technical and economic optimization
  • Investment decision support

This integrated approach creates a stronger basis for selecting the right concept before moving into the next project phase.

Heat Exchanger Design, Rating & Optimization

Thermal and Hydraulic Engineering for Industrial Applications

P&P also provides engineering support for the design, rating and optimization of industrial heat exchangers.

Process simulation can be combined with thermal, hydraulic and mechanical engineering considerations to evaluate equipment performance within the overall process.

Typical applications include:

  • Heat exchanger sizing and rating
  • Thermal performance evaluation
  • Pressure-drop analysis
  • Operating scenario evaluation
  • Heat recovery optimization
  • Integration of heat exchangers into existing process systems

The result is not an isolated equipment calculation, but an engineering solution considered within the context of the complete process.

Specialized Process Modelling for Sulfuric Acid & Gas Treatment Applications

Process Expertise for Complex Industrial Systems

P&P's process engineering experience is particularly suited to technically demanding applications such as sulfuric acid plants, sulfuric acid regeneration, absorption systems and industrial gas treatment.

Advanced modelling approaches can be applied where conventional equilibrium calculations alone are not sufficient, including rate-based modelling of industrial absorbers and complex gas-liquid systems.

This combination of process know-how and advanced simulation is particularly valuable when evaluating existing plants, revamps and new process concepts.

Integrated Aspen-Based Engineering Services

Services can be provided for a specific engineering challenge or as part of a larger feasibility, FEED or project development study.

Depending on the project and engineering phase, P&P can provide:

  • Aspen Plus process modelling
  • Aspen HYSYS process simulation
  • Process model validation
  • Mass and energy balances
  • Vapor-liquid equilibrium calculations
  • Process optimization and scenario studies
  • Heat exchanger design and rating
  • Equipment sizing
  • Energy optimization
  • CAPEX and economic evaluation
  • Feasibility studies
  • Technical reports and engineering documentation
  • Support for revamps and new plant concepts
