Abstract

Abstract

Biodiesel production can be done using static mixing reactor (SMR). The production by this method requires less energy than blade agitator. However, the use of elements in the helix-shaped stirrer reactors causing large pressure drop. The other factors that affect the flow in the SMR can be determined using dimensional analysis. Dimensional analysis can be used to eliminate the variables that are not required so that can be done to optimize the energy used in the SMR design. The variables that influence the pressure drop (ΔP) in the SMR can be formulated into mathematical equation as:

Total irreversibility due to the use of a static mixer in the SMR tested is 0.237 W.

Abstrak

Produksi biodiesel dapat dilakukan dengan menggunakan reaktor berpengaduk statis atau SMR (Static Mixing Reactor). Pembuatan biodiesel dengan metode ini membutuhkan energi yang lebih kecil dibandingkan dengan menggunakan blade agitator. Namun demikian penggunaan elemen pengaduk yang berbentuk helix dalam reaktor menimbulkan pressure drop yang besar. Faktor-faktor lain yang berpengaruh terhadap aliran di dalam SMR dapat ditentukan dengan menggunakan analisis dimensional. Analisis dimensional mampu menghilangkan variabel-variabel yang tidak diperlukan sehingga dapat dilakukan untuk mengoptimalkan energi yang digunakan dalam perancangan SMR. Variabel-variabel yang berpengaruh terhadap pressure drop (ΔP) di dalam SMR yang dapat diformulasikan ke dalam bentuk persamaan matematis sebagai:

Ketakmampubalikan total akibat penggunaan elemen berpengaduk statis yang diuji adalah 0,237 W.
