ABSTRACT OF M.TECH PROJECT

Title: Study on Evolution of Morphology during mixing
of a polymer
blend in a screw extruder

The Properties of Polymer Blends are largely
determined by the
morphological structure of the polymer combinations
that are involved. In terms
of the extruder design, this means it is necessary to
estimate the
development of the morphology over the length of the
extruder. The
formation of initial morphology and its further
development over the length of
the extruder excluding the die section was studied.
The morphology was
studied in terms of reducing striation thickness of
the dispersed
phase. In the frame work of this study, experimental
investigations were
conducted into Polypropylene/Ethylene vinyl acetate
blends with varying
compositions of 70/30;80/20/90/10. The blending
temperature was 200 C and
the screw speed was maintained at 20 rpm. The neat
polymers were
thermally characterized by DSC and TGA techniques.
They were also
rheologically characterized at the blending
temperature. Screw-pullout experiment
was carried out to obtain the samples from the screw.
The technique
polarised light microscopy with the combination of an
Image analyzer was
used to analyse the samples for measuring striation
diameters in the
melting zone of the screw where the striations are
dominant. This
analysis was carried out in each and every channel
over the whole length of
the screw. Scanning electron microscopy was used to
investigate the
morphological changes in the metering zone of the
screw. This is because, in
melting zone the morphology is coarser and in the
metering zone it is
finer. This study of blend morphology reveals the
pattern of morphology
development taking place inside the screw. The pattern
of morphology
variation inside a single channel was investigated
over the length of the
screw. The mechanical performance of the blends were
also obtained in
terms of tensile, impact and flexural properties.

ABSTRACT OF B.TECH PROJECT

Title: Manufacture of Phenol (21,000MTPA)

The Project dealt with the overall engineering
requirements for the
manufacture of Phenol (21,000MTPA). The raw materials
used were cumene,
air, alkali and Sulphuric acid, the byproduct acetone
being a valuable
one.The reaction takes place in two sequences. In the
first sequence,
cumene and oxygen react to form cumene hydroperoxide
and the latter gets
decomposed in a cleavage reactor to produce phenol
and acetone and the
reaction temperature used is 80-120 C. Phenol has an
antiseptic
property and is most widely used for medical purposes.
Phenolic resins are the
major outlet for phenol production. A detailed flow
sheet, material and
energy balances for various equipment were shown. The
design aspects of
major equipment were also shownin detail. Cost
estimation of a plant
for the production has been worked out.
