Slurry Bubble Column Reactor merupakan reaktor multi fasa yang biasa digunakan dalam industri kimia, akan tetapi jenis reaktor ini tidak tersedia di laboratorium jurusan Teknik Kimia POLBAN. Oleh karena itu disusun penelitian yang bertujuan untuk merancang dan membuat simulator reaktor tersebut dalam skala laboratorium, serta melakukan karakterisasi. Tahapan penelitian mencakup perancangan reaktor, fabrikasi reaktor, uji karakteristik rezim aliran, uji karakteristik sifat kedekatan dengan reaktor ideal dan karakterisasi tekanan gas keluaran reaktor. Reaktor yang dibuat mempunyai volume kerja 1 Liter, tinggi reaktor 550 mm dan diameter dalam 60 mm. Air digunakan sebagai fasa cair, udara digunakan sebagai fasa gas dan resin dengan diameter partikel 0,5 mm digunakan sebanyak 0,15 fraksi volume. Dilakukan pengamatan tentang pengaruh laju alir gas terhadap rezim aliran dan menghasilkan rezim discrete bubble flow pada laju alir gas 1-2 Liter/menit, rezim bubbly flow pada laju alir gas 5-7 Liter/menit dan rezim coalesced bubble flow pada laju alir gas 11-15 Liter/menit. Pendekatan sifat reaktor terhadap reaktor ideal didasarkan pada kurva Residence Time Distribution (RTD) dan nilai dispersion number, didapati bahwa pada rezim discrete bubble flow mendekati sifat PFR (Plug Flow Reactor) sedangkan untuk bubbly flow dan coalesced bubble flow mendekati sifat CSTR (Continous Stirred Tank Reactor). Kata kunci: simulator, Slurry Bubble Column Reactor.

Slurry Bubble Column Reactor is multiphase reactor which usually used in chemical industry. However, in POLBAN's Chemical Engineering Department Laboratory, this kind of reactor is unavailable. This research aims to design, build and characterize a laboratory scale slurry bubble column reactor. Include reactor design, reactor fabrication, flow regime characterization, reactor approach to ideal reactor and output pressure characterization. The reactor being made has 1 Litre of working volume, 550 mm length and 60 mm inside diameter. This reactor uses water as liquid phase, atmospheric air as gas phase and resin as solid phase. The resin has 0,5 mm diameter particle and resin used as much as 0,15 volume fractions. Experiment on the effect of gas flow rate resulted discrete bubble flow at 1-2 Litre/minute, bubbly flow at 5-7 Litre/minute and coalesced bubble flow at 11-15 Litre/minute.Characteristic of reactor has been compared with ideal reactor based on RTD (Residence Time Distribution) curve and dispersion number. At discrete bubble flow regime, this reactor approaching PFR (Plug Flow Reactor) character. At bubbly flow and coalesced bubble flow regime approaching CSTR (Continous Stirred Tank Reactor) character. Keywords: simulator, Slurry Bubble Column Reactor.
