| Description |
Lube refineries in India are facing pollution problems
associated with the occasional loss of furfural
from their solvent recovery column bottoms in the
extraction plant, which constitute both an economic
loss and an environmental hazard. Although earlier
studies on furfural removal by adsorption on polymeric
resins concentrated on equilibrium and kinetic/
breakthrough measurements in small diameter
columns in the adsorption, the regeneration of the
loaded resin adsorbent has not been given adequate
attention. This paper focuses on these issues and
also includes studies on larger diameter columns
with a view to provide data for design of a pilot
scale plant for furfural recovery to be set up in a
lube complex. The experimental data from adsorption
cycle studies indicate that the resin bed is able
to treat 28 bed volumes of furfural laden water
bringing down the furfural concentration from 500
ppm to less than 10 ppm. The regeneration data
indicate the recovery scheme produces an aqueous
stream which contains 3% furfural which has to be
taken back to the solvent recovery column in the
extraction complex. Adsorption and regeneration
data have been simulated respectively by the LDF
and diffuse wave model. 2008 American Institute of
