Technical office for system and plant engineering

The technical office is responsible for the planning and implementation of new process engineering systems in the CCLab and the conversion modification of existing systems.

This includes optimization of the plant technology, planning and supervision of extensions for scientific purposes as well as supervision of control systems units and process control systems. Examples include upgrading the high-pressure entrained-flow gasifier (HP-EFG) from biomass-based to plastic-based pyrolysis oils and project planning for the fluidized bed pyrolysis plant for plastics.

The group also supports operations in the planning and implementation of campaigns.

  • Planning methodology and tools
  • Preparation of planning documents (RI, installationplant layout, interlocking matrix)
  • Procurement of components (inquiry, offer evaluation)
  • SIL consideration, CE certification 
  • Programming and support of process control systems
  • Construction supervision; deadline tracking
  • Commissioning
  • Operating manuals and instructions
     

  • Optimization of the quench circuit (system operating time)
    Adaptation of the filter surface and pore diameter for longer service life and adaptation of the equipment for safe replacement of the filter basket during operation.

  • Optimization of wastewater treatment (throughput, treatment capacity)
    Adjustment of wastewater temperature via closed circuit management and additional heating, increase in ammonia separation capacity due to additional treatment column, operation optimization by integration of the control system into the process control system (PCS).
     
  • Planning and implementation optical probe system (observation of gasifier flame in reactor)
    Viewing angle can be rotated and adjusted at shutdown, integration in explosion-protected environment, protection of the pressure-resistant glass disc against gas leakage, optimization of glass flushing to enable longer recording times.
     
  • Optical access to pressurized reaction chamber
    Installation of pressure-resistant glass discs and protection against gas leakage (quick-closing valves), optimization of glass disc flushing to enable longer recording times, movable unit to enable alternative acoustic measurements.
     
  • Laser system for 3D-measuring of the cooling screen 
    Laser system for recording the internal geometry of the cooling screen to determine the slag thickness in the cold state
     
  • Optimization of slag discharge system
    Replacement of slag lock valves and slag lock from 135 to 350 mm free passage
     
  • Conversion of gas heater and hot gas cleaning reactor
    Replacement of horizontal gas heater by a vertical gas heater including a reaction section for higher gas temperatures
     
  • Integration of a micro gas turbine (MobGT) into the bioliq plant network
    Coupling of a micro gas turbine to the synthesis gas line of the HP-EFG 
     
  • Hydrogenation
    Planning of a plant for the hydrogenation of pyrolysis condensates (upgrading of chemical properties)
     
  • Fluidized bed pyrolysis for plastics
    Planning and realization of a fluidized bed pyrolysis for the thermal decomposition of mixed plastic waste. As residues from mechanical recycling processes, these types of material streams cannot yet be recycled in the sense of a circular economy. Pyrolysis is therefore a supplement to established processes and can increase the proportion of recycled waste
