Engineering technology know-how

As a long-term partner of industry having comprehensive process expertise, we have gained experience in implementing technology know-how for about 50 years.

We accompany our clients during engineering technology independently and individually from feasibility study to implementation stage. In doing so, we deal with complex procedural basic design incl. process simulation, materials and energy balance, P&ID and execution basis of design for subsequent trades.

Our services for process engineering

  • Simulation of new plants and optimisation of existing plants
  • Preparation of materials balances
  • Preparation of block flow diagrams, PFDs, P&IDs
  • Hydraulic design and optimisation
  • Design and recalculation of shell and tube heat exchangers
  • Design and retrofitting of equipment
  • Design of I&C and safety-relevant valves, like control valves and safety valves
  • Design and optimisation of flare systems
  • Safety considerations for process plants
  • Authority engineering
  • Process descriptions and operating manuals
  • Operator training and start-up support

Electrolysis and power-to-X units

The sectors of green technology and H2 also benefit from our comprehensive competence in the field of technology development.

As Griesemann Gruppe, we make our contribution to realising future-proof projects for electrolysers, hydrogen units and power-to-X units by engaging the existing processes early and intensively.

Thanks to our approach throughout all trades, long-time experience in project control and interface management as well as using all engineering and installation trades in-house, we set standards in the field of integrated project implementation, too.
