  • Training and technical support to start
  • Accompaniment during startup of the plant
  • Support to plant operations
  • Troubleshooting
  • Research team specialized in anaerobic digestion
  • Evaluation of the potential technologies (pretreatments, digesters, biogas valorization)

 

Exemple of CNETE equipment for process control

Anaerobic digester of 4500 liters

Pilote 4500

 

Specifications

  • 1 digester of 4500 L, with volume of useful work of 4000 L
  • 1 pretreatment/storage tank of 1500 L to feed the digester
  • Programmed automaton for continuous 24h digester feeding
  • Agitation of the 2 tanks with Netzsch progressive cavity pump, connected to the automaton
  • Variable feed rate from 50 L/min to 500 L/min
  • Completely sealed, made of stainless steel
  • 4-inch input and output with pneumatic valves for inputs and discharge of digestate
  • Heating by double wall coil, ranging from 21°C to 70°C
  • Gas outlet to a flare, with flow measurement and gas collection for analysis
  • Qualitative analysis of biogas (O2, N2, CO2, CH4, H2S) with a Sewerin Multitec 540 portable analyzer

 

Examples of application

  • Pilot scale process development, continuous (Fed-batch)
  • Optimization of mechanical parameters of methane production (OLR, HRT)
  • Optimization of physicochemical parameters of methane production (pH, T°C, etc.)
  • Toxicity and inhibition tests of some inputs/co-inputs
  • Evaluation of biogas production with preprocessed input (enzymatic/thermal/chemical)

 

In addition, through its extensive knowledge and expertise, the CNETE team has developed a software tool, Biometh i+, that functions as a decision-simulator for calculating the feeding stream of the digester and acts as a tutorial for decision making and conducting daily operations. This tool allows among others to calculate the mixture and the optimal dilution of inputs upon insertion in the process. In addition, this tool tags operations considering over 14 physical and chemical parameters simultaneously and makes recommendations in case of non-compliance levels of these parameters at the time of their determination.
