EVALUATION OF SUB-PROCESS POLYPROPYLENE PURIFICATION UNIT DUE TO INCREASING OF FEED CAPACITY AND FEEDâS COMPOSITION CHANGE
Feed of purification unit at polypropylene production is the output of Fluid Catalytic Cracking Unit (FCCU). At this time reliability of FCC unit has obstacles so that FCC unit development program (revamping) is carried out. This revamp cause capacity increase and change of propylene purification...

description |
Feed of purification unit at polypropylene production is the output of Fluid
Catalytic Cracking Unit (FCCU). At this time reliability of FCC unit has obstacles
so that FCC unit development program (revamping) is carried out. This revamp
cause capacity increase and change of propylene purification unit feed’s
composition. So, performance evaluation need to be conducted at propylene
purification unit.
This study focused on evaluating capacity change and composition change of the
propylene purification unit’s feed after revamping of FCC Unit as the main source
of Raw Propane Propylene (Raw-PP). The purification unit in the polypropylene
refinery is used to purify Raw-PP to produce high quality propylene with
composition of 99.6% propylene. This is intended to meet feed specifications of
polimerization unit, so that propylene could be polymerized in the next unit.
Feed after revamp scope are increasing of volumetric flowrate and composition
change. Analysis of this study use simulation and modelling by Aspen HYSYS V10
based on operating condition and process equipment.
Result shows that this system could process feed after revamp after some
modification. Existing operating condition could be maintained but feed should be
limited its H2S content from 6000 ppm-mol (existing) to max 2750 ppm-mol and
CO2 content from > 1000 ppm-mol (existing) to 250 ppm-mol. However, process
equipment need to be modified including installing new dryer unit with minimum
capacity 3.4 ton/h and Depropanizer column modification by adding minimum 20
number of theoritical trays.
