Tujuan dari penelitian ini adalah untuk mendapatkan
properti thermodinamika tekanan uap dari blending alkoholgasoline.
Untuk alkohol digunakan Ethanol dan n-Buthanol
sedangkan untuk gasoline digunakan iso-Octane. Sistem yang
diteliti adalah sistem biner yaitu n-Buthanol1-Ethanol2 n-
Buthanol1-iso-Octane2 Ethanol1-iso-Octane2 pada range
temperatur 30 oC -55 oC. Peralatan yang digunakan adalah
Ebulliometer yang dimodifikasi dengan manometer air raksa
untuk mengukur tekanan dalam cell. Peralatan yang digunakan
pada eksperimen ini divalidasi untuk mengukur tekanan uap
ethanol murni dan iso-octane murni. Data eksperimen
dibandingkan dengan literatur sehingga diperoleh hasil 0.5
untuk Ethanol murni dan 0.6 untuk isooctane murni. Dari
perhitungan korelasi diperoleh persen rata rata kesalahan
absolute AAD antara tekanan uap eksperimen dengan
perhitungan sebesar 0.06 untuk Persamaan Wilson 0.07
untuk Persamaan NRTL dan 0.19 untuk Persamaan UNIQUAC.
ABSTRACT
The aim of this research was to determine experimentally vapor
pressure of alcohol-gasoline blends. Ethanol and n-buthanol were
used as alcohol components and isooctane was used to represent
gasoline. The binary systems studied were n-buthanol-ethanol nbuthanol-
isooctane and ethanol-isooctane. The experimental
apparatus used in this work was modified Ebulliometer completed
with mercury manometer to measure the equilibrium pressure.
The experimental apparatus was validated by measuring vapor
pressure of pure ethanol and isooctane. The data were compared
to literature data with average absolute deviation AAD of 0.5
and 0.6 for vapor pressure of ethanol and isooctane
respectively. The vapor pressure of three binary systems obtained
in this work could be classified as non ideal solutions. The
experimental data were correlated using Wilson NRTL and
UNIQUAC equations with AADs of 0.06 0.07 and 0.19
respectively.
