ANALISA PERFORMANCE HEAT EXCHANGER E-201 PADA PROSES PRE-TREATMENT GLISERIN DI PT SARI DUMAI SEJATI --

ABSTRAK
Analisa performance heat exchanger E-201 dapat dilihat melalui nilai Uc, Ud, Rd
dan nilai effisiensi pada heat exchanger E-201. Tujuan dari penelitian ini adalah
untuk mengetahui nilai efisiensi heat exchanger E-201 dan mengetahui pengaruh
dari laju alir dan suhu steam terhadap nilai LMTD, Uc, Ud, Rd dan pressure drop.
Penelitian ini dilaksanakan pada bulan Februari – Juli 2023 di PT. Sari Dumai
Sejati, Riau. Pada penelitian ini menggunakan alat Heat Exchanger Tipe Shell and
Tube yang ada di section 2 oleochemical plant. Adapun variabel berubah dari
penelitian ini adalah flow feed : 15.873,28 lb/hr 18.739,29 lb/hr 16.534,67 lb/hr
11.464,04 lb/hr dan 19.180,21 lb/hr dan suhu : 211,21 0F 242,1 0F 248,41 0F
dengan variabel respon LMTD, ?P, Nilai coeffisien clean overall (Uc), Nilai
coeffisien dirt overall (Ud), Nilai fouling factor (Rd), Efisiensi Nilai effisiensi
terbaik terdapat pada laju alir 19180,21 lb/hr dengan nilai effisiensi sebesar 201%
dan nilai effisiensi terendah terdapat pada laju alir 11464,04 lb/hr dengan nilai
effisiensi sebesar 120 % . Besar kecilnya flow feed dapat mempengaruhi nilai
effisiensi dari heat exchanger E-201. Flow feed yang digunakan di lapangan
sebesar 16.000 lb/hr agar penggunaan alat heat exchanger E-201 lebih effisien
ketika digunakan.

ABSTRACT
Analysis of the performance of the E-201 heat exchanger can be seen through the
Uc, Ud, Rd values and the efficiency value of the E-201 heat exchanger. The
purpose of this study was to determine the efficiency value of the E-201 heat
exchanger and to determine the effect of the flow rate and steam temperature on
the values of LMTD, Uc, Ud, Rd and pressure drop. This research was conducted
in February - July 2023 at PT. Sari Dumai Sejati, Riau. In this study, a Shell and
Tube Type Heat Exchanger was used in section 2 of the oleochemical plant. The
variables that changed from this study were flow feed: 15,873.28 lb/hr 18,739.29
lb/hr 16,534.67 lb/hr 11,464.04 lb/hr and 19,180.21 lb/hr and temperature:
211.21 0F 242 , 1 0F 248.41 0F with the response variable LMTD, ?P, Clean
overall coefficient value (Uc), Overall dirt coefficient value (Ud), Fouling factor
value (Rd), The best efficiency value was found in the flow lane 19180.21 lb/hr
with an efficiency value of 201% and the lowest efficiency value was at a flow rate
of 11464.04 lb/hr with an efficiency value of 120%. The size of the flow feed can
affect the efficiency value of the E-201 heat exchanger. The flow feed used in the
field was 16,000 lb/hr so that the use of the E-201 heat exchanger was more
efficient when used.
