Abstract:
The Determine which of solvents and amount and under what conditions of temperature, stirring time, stirring speed, will most efficiency remove residual gear oil from a mixing vessel. This represents cleaning of blending vessel in large lubrication oil blend plant. From experiment, D80 can clean mixing tank better than another solvents. The best condition for cleaning are 25 gram of solvent, 524 rpm of stirring speed, 15 second of stirring time. Residual of gear oil is 7.0%. The best case is 120 second of stirring time, residual of gear oil is 0%.
