ANALISA PERFORMANCE CLIMBING FILM EVAPORATOR TYPE MULTIPLE EFFECT PADA SECTION 3 GLYCERINE WATER EVAPORATION DI PT. SARI DUMAI SEJATI --

ABSTRAK
Minyak kelapa sawit berasal dari tumbuhan kelapa sawit (Elais Guineensis
Jacq), merupakan salah satu komoditas ekspor utama Indonesia dan memiliki peran
penting dalam industri hilir. Termasuk di PT. Sari Dumai Sejati yang mengolah
minyak sawit menjadi produk turunannya seperti glycerine dan fatty acid pada unit
Oleochemical plant. Penelitian ini menganalisis performa evaporator dalam
melakukan pemekatan Crude Glycerine dengan range 80% - 88%. Proses
pemekatan dilakukan pada section 3 glycerine water evaporation dengan
menggunakan evaporator berupa climbing film tipe multiple effect. Data penelitian
diperoleh melalui observasi langsung di lokasi produksi, dengan menganalisis
efisiensi pemekatan, suhu, dan kandungan glycerine. Penelitian ini bertujuan untuk
menganalisa performa evaporator dengan menggunakan beberapa parameter untuk
menghasilkan serta membandingkan nilai Q aktual dan nilai Q desain pada masing-
masing effect nya. Berdasarkan hasil penelitian ini, evaporator masih dapat
dikatakan layak dalam melakukan pemekatan crude glycerine dengan range 80% -
88%. Sebab nilai efisiensi yang didapatkan cukup baik di tiap effect nya.

ABSTRACT
Palm oil originates from the oil palm plant (Elais Guineensis Jacq),
constituting a significant primary export commodity for Indonesia and playing a
pivotal role in downstream industries. This includes PT. Sari Dumai Sejati, which
processes palm oil into its derivative products such as glycerine and fatty acids at
the Oleochemical plant unit. This research examined the performance of an
evaporator in concentrating Crude Glycerine within the range of 80% - 88%. The
concentration process occurred in section 3 of glycerine water evaporation using a
multiple-effect evaporator of the climbing film type. Research data was acquired
through on-site direct observations, involving an analysis of concentration
efficiency, temperature, and glycerine content. The objective of this study is to
assess the evaporator's performance using various parameters to generate and
compare the actual Q value with the designed Q value for each effect. Based on the
outcomes of this study, the evaporator could still be considered proficient in
concentrating crude glycerine within the 80% - 88% range. This was due to the
satisfactory efficiency values obtained for each effect.
