Abstract
Unit destilasi minyak mentah adalah unit pertama yang digunakan dalam industri penyulingan minyak.
Dari unit distilasi, fraksi minyak bumi seperti nafta, minyak tanah, solar dan
minyak gas dapat diperoleh untuk pasokan listrik dan sebagai umpan di industri lain. Tujuan dari
Makalah ini untuk mendapatkan suhu pengumpanan dan posisi penari telanjang yang dapat memberikan
keuntungan tertinggi di kilang. Simulator Aspen Plus digunakan untuk melakukan
simulasi. Temperatur tungku pada kolom Preflash dan posisi strippers
pada kolom Pipestil adalah variabel desain. Kualitas ujung yang ringan, berat
naphtha dan diesel dalam 95% ASTDMD86 ditetapkan konstan pada 130ᵒC, 190ᵒC dan
222ᵒC masing-masing. Kondisi optimum ditentukan berdasarkan maksimum
keuntungan dan itu terjadi ketika suhu dalam tungku kolom preflash
345ᵒC sedangkan posisi pengupas pada pipestil adalah S1p.5-4, S2p.14-13 dan S3p.1918

==============================================================================================
The crude distillation units are the first units used in oil refinery industry.
From distillation units, petroleum fractions such as naphtha, kerosene, diesel and
gas oil can be obtained for power supply and as feed in other industries. The aim of
this paper is to get the feed temperature and strippers position which can provide
highest profit in the refinery. Aspen Plus simulator was used to perform the
simulation. The temperature of furnace on Preflash column and strippers position
on the Pipestil column are the design variables. The quality of light ends, heavy
naphtha and diesel in the 95% ASTDMD86 was set constant at 130ᵒC, 190ᵒC and
222ᵒC respectively. The optimum condition was determined based on the maximum
profit and it happened when the temperature in the furnace of preflash column was
345ᵒC while strippers’ position on pipestil was at S1p.5-4, S2p.14-13 and S3p.1918
with
a
profit
of
USD54.93/m³.
No

when
the feed temperature or stripper position was changed. The deviation that
occurred was normal, therefore CDU operation was satisfying for all cases
