This work is focused on description of gravitation separation process of the ester
phase from the glycerol phase for biodiesel production. Four mathematical
models describing separation were created. Two independent methods were used
for monitoring of separation: the first method is based on the determination of the
time dependence of the actual amount of the glycerol phase on the bottom of a
sedimenting vessel by digital camera records. The second one measures light
absorption changes caused by the lowering of the glycerol phase during the
sedimentation. The obtained data was curve fitted by developed mathematical
models, which are (i) based on Stokes equation and proposed distribution
function, (ii) based on analogy to reaction kinetics. The distribution function has
several simplified presumptions, e.g., interactions are neglected, the function has
one peak. The obtained model parameters (from the curve fitting) can be consequently used for the quantification and the prediction of sedimentation
behaviour such as the sedimentation conditions, the size of settling devices and the
evaluation of dependences on raw material quality. |
