Aeration System of biodiesel reactor
The diagram above allows us to have a brief understanding of how the biodiesel reactor works. However, glycerol which is a side product of the transesterification reaction is denser than biodiesel and will settle at the bottom of the reactor. This might cause clogging of the aerator and cause the aeration system to be ineffective thus different aeration systems have to be investigated.
In the above diagram, The aeration system 4 aeration rings labelled 15,16,17 and 18 are used. This provides more reliable aeration as if one aeration ring is clogged there are others that can still function. More aeration rings would allow more and even bubbling throughout the waste cooking oil thus allowing more surface area for transesterification to take place. It can be suggested for a side glass window to be installed to as to monitor glycerol level in reactor, as well as a drainage valve to be installed at the bottom of the reactor to drain away glycerol that settles at the bottom of the tank.
The above article provides information about Spargers which can be used in the aeration system of the biodiesel reactor as an alternative to aeration rings.
An aeration system is required in the biodiesel reactor to bubble waste cooking oil so as to increase surface area for transesterification reaction between waste cooking oil and methanol. Thus a suitable aeration system has to be sourced.
