摘要
Particle separation is an important stage in industry, especially in chemical and mineral industry. Some common methods in separation are filtration, gravitation and centrifugal (cyclone). A new method of separation, namely fluidized bed, needs to be explored because it produces low pressure drop and high efficiency. Experiment was performed using bio-solar (diesel fuel) as fluid and silica gel with radius 0.8 mm and 3 mm as solid particle. The goal of experiment is obtaining maximum separation of small particle (0.8 mm) and maintaining minimum separation for big particle (3 mm). Fluid velocity is ranging from 0.034 – 0.118 m/s where the slowest velocity is still above minimum fluidization velocity for small particle, and the maximum velocity is still smaller than terminal velocity of big particle. There are 3 (tree) outlet height of fluidized bed, namely: 0.3, 0.6 and 0.9 meter. According experiment result, the increase of velocity will slightly increase pressure drop but it highly increases separation percentage. An optimum separation occurs on velocity of 0.118 m/s and outlet 0.9 meter where separation efficiency of small particle as high as 98 percent and big particle separation is less than 2 percent.
