Biogas monitoring is one of the significant works that determines quality production of biogas. Every step and every biomass fed to the system is monitored to have a scientific analysis to increase the productivity of biogas from the plant. Biogas monitoring technique gives us some quality result as why some process is producing more biogas than others and many more data. There are certain methods of monitoring. I would like to mention below biogas montiroing process. These are simple chemical process or chormatography process to analyse the biogas.
1. Titration:- This is a simple chemical process which shows the value of pH in the digester. Knowing th pH value of digester and maintaining it to optimum value as per research makes most output from biomass. If pH is increased too much or reduced too much then biogas production from biomass will be affected drastically. So, measurement of pH and maintaining is necessary for digester.
2. Gas chromatography:- Gas chromatography is used to analyse the component of gas that can't be decomposed.Typical uses of Gas Chromatography of biogas include testing the purity of a particular substance viz biogas, or separating the different components of a mixture (the relative amounts of such components can also be determined). In some situations, Gas Chromatography may help in identifying a compound. Inpreparative chromatography, This helps in analyzing the biogas and deciding the purity and different contents of biogas.
3.MIMS:- which is one of the new measuring methods that the researchers expect a lot
from. The equipment is able to continually register the accumulation of fatty acids in
the gas, which means that you have time to intervene if the process shows signs of
imbalance.
4.NIR:- which like MIMS is one of the new methods that there are great expectations
for. In this case, there are also online measurements, but instead of measuring the gas
quality, you register what takes place in the reactor using infrared radiation.
