Biogest Bioquadrat, Enerfees, France: Biogas Plant for the Production of Biogas from Biomass and Manure

CHALLENGES / PROBLEMS

  • Complete automation of the entire plant: Designing software to minimize operator interaction with the system.
  • Local and remote system management: Utilizing Central WinCC SCADA and five local Siemens HMI touch panels.
  • SMS reporting for alarms and events.
  • Establishing communication and signal exchange with several different vendors.
  • Programming of hygiene systems.
  • Programming two systems for solid feeding.

SOLUTION

  • Implementing redundant software and hardware protections along with a management approach to ensure the system can safely respond to emergencies.
  • Employing Siemens WinCC SCADA as the central management system and five local Siemens HMI touch panels with secured VPN access.
  • Allowing operators to define alarms and events that can be sent via SMS messages to selected phone numbers.
  • Integrating and managing machines and devices from different vendors through Modbus TCP, Modbus RTU, and S7 communication.
  • Developing a custom solution for maintaining hygiene in the processed material using a batch system with three tanks, ensuring the appropriate temperature and total processed volume, in compliance with legally mandated treatment standards, similar to pasteurization.
  • Creating a comprehensive software solution for two solid feeders, one of which supports continuous feeding through automatic crane replenishment, facilitated by “flow” measurement of the dosed weight.

BENEFITS

  • Achieving full automation of the entire plant.
  • Attaining a high level of autonomy in plant operation.
  • Implementing redundant software protections to ensure a prompt response to emergencies.
  • Shifting the operator’s role towards material management and responding to system notifications and warnings.
