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.
