Monitoring system for laboratory scale digestion system
Abstract:
A monitoring system for laboratory scale digestion system was designed and installed for
experiments. The system was designed to measure biogas production and system parameters. These
included flow rate, temperature, methane concentration and level of water. The main objective was to
collect real-time data during digesting period. The digestion system consisted of seven digestion tanks
which were placed in a controlled temperature water tank. Each digestion tank had a volume of 20 liters.
Seven flow meters, seven thermocouples, one methane concentration sensor and one optical level sensor
were installed. The monitoring system was controlled by two Microcontrollers. Data were collected using
a Visual C# program. The monitoring system was calibrated after installation. The monitoring system
was tested by operating the digestion system using Napier grass as feedstock. Data collection during one
month digestion period was performed. The monitoring system was able to measure data from different
transducers satisfactory.
