An oil treating system is described for rapid and efficient mixing of an oil treating agent with oil in a tank of oil on-board a tankship, comprising: a container of oil treating agent, means for creating a plume of gas bubbles rising in the oil in the tank, the means for creating a plume of gas bubbles comprising a source of pressurized gas, a first conduit for delivery of the gas from the source to the bottom of the tank, and a second conduit disposed adjacent to the bottom of the tank. Below the surface of the oil, the delivery of the gas from the first conduit to spaced perforations defines the wall of the second conduit. The gas passes then from the second perforated conduit into the oil via the perforations. A vent means allows escape of gas from the tank, and means for introducing the oil treating agent into the plume of gas bubbles rising in the oil. Rising gas bubbles induce upward flow in the oil in their vicinities with counterbalancing downward flows elsewhere in the oil, with turbulence generated by flow of oil around the bubbles and in their wakes. Rapid and efficient mixing of the treating agent into the oil is executed.
