Abstract

Penelitian ini bertujuan untuk mengkaji secara teoritis
berbasis CFD proses gasifikasi batubara kualitas rendah di
dalam gasifier mengenai pengaruh rasio Of coal terhadap
distribusi temperatur dan distribusi produk.
Geometri gasifier yang digunakan berbentuk silinder
dengan ukuran gasifier L/ D=10,25 dengan D=0 ,2 m. Batubara
diinjeksikan kedalam gasifier dalam bentuk slurry setelah
ditambahkan air dengan konsentrasi 58% berat. Jenis batubara
yang digunakan adalah batubara Senakin yang berasal dari
Kalimantan yang termasuk ke dalam tipe batubara subbituminous
(343 K) dan oksigen sebagai oksidiser (293K). Variabel yang
digunakan adalah variasi rasio Of coal.
Hasil yang diperoleh dalam simulasi tiga dimensi berupa
distribusi tempertur, distribusi fraksi massa untuk rasio Of coal
yang berbeda. Semakin tinggi rasio Of coal temperatur juga
semakin tinggi. Kenaikan rasio Of coal menyebabkan jumlah
produk H 2 dan CO menurun tetapi jumlah produk CO2 meningkat.
==================================================================================================
Computational Fluid Dynamics can be used to analize the
effect of massflow inlet oxygen - coal on fluid flow profile and
product distribution on low rank coal gasification process in a
gasifier.
Cylinder geometry is used for gasifier with L/D = 10.25
where D = 0.95 m. Coal water mixture with 58% concentration
injected into gasifier. Coal type which applied is Senakin coming
from Kalimantan which included into type subbituminous coal
(343 K) and oxygen as oksidiser (293 K). Variabel which applied
is various ratio Ofcoal.
The results of this research are showed, temperature
distribution, mass fraction of gasification product distribution for
different ratio Ofcoal,
decreases the H2 and CO concentration but increases the C02
concentration in the product gas.
