Automatic crude oil tank cleaning process and the sludge recover system is the use of spray cleaning machine will clean the media at a certain temperature, pressure and flow under the jet to the surface to be cleaned to remove surface condensation and sludge, and processed and recovery of a process method,

The cleaning medium is oil or the same medium. According to the construction requirements and site conditions, water and diesel fuel as a cleaning media are also used after washing the crude oil, light crude oil contains components that solvent composition, accelerated oil deposits in the coagulation and sludge disintegration, crushing after cleaning sludge and oil mixture, dissolution, diffusion, eventually pumping recycled. With crude oil washing process to be more pure crude oil, usually need to have a clean tank and being adjacent to the tank, the tank usually recovered as a crude oil tank.

Crude oil tank cleaning equipment and cleaning and recycling cans with the process piping connected together to form a cleaning system.
