Anaerobic Digestion Modeling

Anaerobic digestion modeling is the primary focus of our Modeling and Simulation (ModSim) service. We analyze all types of data and operating parameters of a biodigester or biogas plant to optimize its design and performance.

Our mathematical modeling and simulation approach represents different processes through equations, including the mass and energy balances of the system and phenomena such as chemical equilibrium, reaction kinetics, inhibition, and gas transfer.

At ProCycla, we leverage known models or develop customized versions to meet the unique needs of each project. Our SCR® monitoring and control system is the backbone of our service.

We offer flexibility in software usage, utilizing commercial tools like Matlab® and open-source programs such as Octave or Python.


How can we help you with MoDSim?

Prediction of new operating scenarios

To achieve optimal biogas production and digestate quality, biogas plants must assess the impact of various factors, such as changes in organic substrates, addition frequency, and temperature.

Our ModSim service provides accurate estimates and degrees of confidence in digester operation under these new conditions.

Diagnosis of the current operational status

Using an appropriate model, we can predict the current status of unmeasured variables related to microbial populations and intermediary compounds. This can help anticipate inhibition events, microbial richness, and/or accumulation of unwanted compounds.

Operator training

Our mathematical models can be used to create simulators to train operators to operate biological processes such as anaerobic digestion. This training provides an efficient and risk-free way to introduce new personnel entering a biogas plant.

Experimental design

Our modeling techniques enable virtual testing of different operating conditions, which eliminates the need for extensive setups and saves significant human, economic, and physical resources.

Digester design and operation

We use computational fluid dynamic (CFD) modeling and simulation to evaluate digester design factors such as mixing type, intensity, and substrate inlet or outlet configuration. In addition to fluid flow, we can incorporate heat transfer, the presence of other species, and other phenomena to achieve a complete system analysis.
