Koefisien Perpindahan Massa pada Ekstraksi Aspal Buton dari Kabungka dan Bau-Bau dengan Pelarut n-Heksan
Butonion natural asphalt can be used for binder in road construction after its impurities were removed by extraction using suitable solvent. Researches on extraction of Butonion asphalt have been done. However, most of them are explorative research.This experiment tried to find mass transfer coeficient for Butonion asphalt extraction. The mass tronsfer coefficient will be used in extraction tower design. In this experiment, multi-stage cross-cwrent extraction was used using n-hexane as a solvent. The number of stages was seven. Bitumen obtained was then distilled to separate the n-hexane. The operation variables were : size of solid, rotation and extTaction time.The relationship of the mass transfer coefficient with other variables can be written as:The constant values of Kabungka asphalt are : K=6.43558x10tt, a=0.141569, b=0.2825804, c =1.76857, d= - 1.381755, e=t.636537x102 ; those of Bau-Bau asphalt are : K= 6.3x I0tt'a = 0.0891, b= 0.28258, c= L7699, d = -1.3821Keywords : extraction, mass transfer, Butonion asphalt
