| Abstract | This study introduces the possibility of using a
refrigerant- filled collect or for the recovery of solvents from
vegetable oils . Due to the high boiling points of classical
solvents , a high operating temperature is required. Thus , the
thermodynamic properties of freon which is the chosen heat
transfer fluid was investigated at different temperature
conditions . A selection was done on the appropriate collector
configuration which satisfies the requirement o f the application
being considered in this study. The importance and methods of
calculating the heat transfer coefficient of a two-phase flow
were also analyzed since this affects the design of the heat
transfer equipment.
A purely hypothetical system was established for the
vaporization of a pure solvent, hexane . The heat transfer medium
for the solar collector was R - 11 3 after conducting the
investigation on its thermodynamic properties . A computer model
written in Turbo Pascal was for mulated by The basic energy
balances to simulate the performance of the system. A non - linear
model of the over-all heat loss coefficient adapted from CSIRO
(1976) was also incorporated in the computer model.
Th e results showed that the production of vapor was
affected by the amount of solar irradiation, the heat transfer effectiveness , the losses to the surrounding , and the load in the
boiler where the vaporization of the solvent takes place . |
