Principle : The principle of this equipment is to prevent the accumulation of sludge on the bottom of the crude oil storage tank using high discharging oil circulating pump, Win’s rotary jet mixer. The high discharge pressure of jet mixer breaks the sludge into small pieces after which the sludge is decomposed and dissolved in the crude oil while the sludge floats up.
Characteristics of crude oil storage tank and sludge
Oil storage tank : The asphalt, tar, wax, etc. in the crude oil deposit on the bottom of the tank while the oil is stored in the tank and these deposits become high viscosity sludge. It is hard to remove the sludge except mechanical crushing or chemical dissolving methods. Due to the oil washing system, all sediments such as rust, scale, mud, sand, etc. in the cargo oil tank flow into the storage tank.
