PARAFFIN INHIBITOR BALLS are primarily used to prevent paraffin deposition in crude oil production systems. PARAFFIN INHIBITOR BALLS inhibit paraffin by the crystal modification method. This method keeps paraffin particles from sticking together. PARAFFIN INHIBITOR BALLS are effective on certain ranges of molecular weight paraffins. Testing the balls for effectiveness can be done by simply trying the balls in the field or by testing the crude oil in the laboratory. To be effective, the inhibitor must be in solution in the oil before paraffin precipitation starts to occur. On produced oil tank applications, the PARAFFIN INHIBITOR BALLS would be dropped through the hatch. The ball will fall to the bottom and dissolve in the water bottom releasing the paraffin inhibitor to migrate up to the oil. As tanks are rolled, the inhibitor is blended with the produced oil.
