PERPINDAHAN MASSA PADA DEKOLORISASI MINYAK KELAPA SAWIT DALAM KOLOM TERISI KARBON AKTIF (MASS TRANSFER IN CRUDE PALM OIL DECOLOURIZATION IN FIXED ACTIVATED CARBON BED)

ABSTRACT One of the efforts to refine crude palm oil is decolourization using activated carbon as an adsorbent in a fixed bed column. This research is conducted to obtain a correlation between Sherwood and Reynolds number that can be applied in designing such a column for commercial purpose, include...
