Description |
The effects of various cooling modes such as natural cooling mode, linear cooling
mode, and controlled cooling modes type A and B in a batch cooling crystallizer
on crystal size distribution (CSD) as well as the mean crystal size have been studied
for DL-malic acid. The natural cooling mode was found to yield crystals in the range
of 250 to 1000 mm, whereas the linear cooling mode was found to yield larger crystals,
in the range of 800 to 1600 lm. The mean crystal size was found to increase in
the order of natural cooling mode, controlled cooling mode A, controlled cooling
mode B, and linear cooling mode. Since linear cooling mode was found to yield larger
mean crystal size, the effect of operating parameters such as the seed concentration
and agitation rates on CSD was assessed using the linear cooling mode.
The increase in seed concentration from 0.5 to 1% resulted in a larger mean crystal
size; while an increase from 1 to 2% reduced the mean crystal size. An agitator rate
of 90 rpm was found to yield larger mean crystal size than agitation rates of 60 and
120 rpm.
