Tobacco dust is by-product of cigarette factory chopping process
The chemical content of dry tobacco dust consists of miscellaneous molecules i.e. nicotine, alkaloid, tar, organic proteins, carbohydrate, aromatic oil, and minerals, impurities of tobacco dust in the form of iron sand and silica sand
The existence of impurities on tobacco dust in the form of iron sand and silica sand for about 10 – 20% makes tobacco dust belongs to hazardous material if it was blended with the air
Summary
Tobacco dust is by-product of cigarette factory chopping process. The chemical content of dry tobacco dust consists of miscellaneous molecules i.e. nicotine, alkaloid, tar, organic proteins, carbohydrate, aromatic oil, and minerals (calcium, potassium, magnesium, sulphur), impurities of tobacco dust in the form of iron sand (magnetite) and silica sand. One of the methods able to be carried out to reduce or relieve the impurities of tobacco dust is separation process with fluidized fixed bed. A constant and low pressure drop in the bed that does not confide in the gas velocity ensures low-energy consumption These factors have led to improve productivity and massive interest in the applications of fluidized fixed bed [4,5]. One of the challenges involves the miscellaneous mixture of gas – solid with liquid – like role This condition for beds with polydisperse particles is operated at high velocities. The separation process in fluidized fixed bed could relieve the sand impurities on tobacco dust less than 5%. The separation process was focused on velocity of the gas flow
