EVALUASI PEMAKAIAN BAHAN KIMIA Ca(OH)2 DAN FILTER AID TERHADAP KUALITAS PRODUK TREATED GLYCERIN KELUARAN TREATMENT VESSEL PADA PROSES PRETREATMEN SWEET WATER GLYCERIN --

ABSTRAK
Untreated Glycerine atau produk keluaran glycerine dari splitting memiliki
tingkat konsentrasi glycerine yang masih rendah sekitar 35% dan masih banyak
pengotor didalamnya seperti oil carry over yang masih cukup banyak. Perlu
dilakukan pemurnian dan peningkatan konsentrasi pada glycerine agar
konsentrasi glycerine meningkat dan pengotor didalamnya berkurang. Tujuan
dari penilitian ini adalah untuk mengetahui efisiensi penambahan bahan kimia
Ca(OH)2 dan filter aid sehingga mendapatkan kualitas dari crude glycerine
yaitu FA & E (Fatty Acid & Ester) dan pH menurut standar mutu plant yang
ditetapkan. Metode yang digunakan yaitu metode analisa data di lapangan dan
data hasil lab Pada penelitian ini akan menentukan berapa efisiensi pemakaian
bahan kimia Ca(OH)2 dan filter aid untuk mendapatkan quality sesuai standart.
Penelitian ini menggunakan data oil carry over sebagai variable berubah dalam
menentukan kualitas dari glycerine dengan variasi oil carry over sebanyak (20,
40, 50, 70 dan 75 liter). Penambahan Ca(OH)2 dan filter aid berturut turut
sebanyak 100 kg dan 130 kg. Didapatkan hasil dari penelitian ini berupa
efesiensi pada saat penetralan pH dan pengurangan kadar FA & E. Hasil
efisensi yang terbaik didapatkan pada kondisi oil carry over sebanyak 50 liter
dengan efesiensi penetralan pada pH sebesar 55,21% dan efisiensi penurunan
kadar FA & E sebesar 39,83%


ABSTRACT
Untreated Glycerine or glycerine output products from splitting has a
low glycerine concentration level of around 35% and there are still many
impurities in it such as oil carry over which is still quite a lot. It is necessary
to purify and increase the concentration of glycerine so that the concentration
of glycerineincreases and the impurities in it decrease. The purpose of this
study is to determine the efficiency of adding Ca (OH) 2 chemicals and filter
aid so as to obtain the quality of crude glycerine, namely FA &; E (Fatty Acid
&; Ester) and pH according to established plant quality standards.The
method used was the method of analyzing data in the field and lab data In
this study would determine how efficient the use of Ca (OH) 2 chemicals and
filter aid to get quality according to standards. This study used oil carry over
data as a variable change in determining the quality of glycerine with
variations in oil carry over as much as (20, 40, 50, 70 and 75 liters). The
addition of Ca(OH)2 and filter aid respectively as much as 100 kg and 130
kg. The results of this study were obtained in the form of efficiency when
neutralizing pH and reducing FA &; E levels. The best efficiency result was
obtained in oil carry over conditions of 50 liters with neutralization efficiency
at pH of 55.21% and efficiency of reducing FA & E levels by 39.83%
