Abstract
Barium sulfate crystals can inhibit the flow rate of fluid in the system piping because barium sulfate crystals will stick to pipes, valves and pumps so that the growth of barium sulfate crystals needs to be controlled. Control Barium sulfate crystals in this study can be made by adding substances additive and stirring speed. Details of the addition of additives and stirring speed using Box Behnken Design with Response Surface Methodology. The purpose of this study to determine the effect concentration of additives (CaCl2, MgCl2) with variations of 5, 15, 25 ppm, speed stirring 120, 360, 600 rpm and stirring time 30, 75, 120 minutes against capture of barium sulfate crystals. BaSO4 3500 ppm is formed by reacting solution of BaCl2 and Na2SO4 at 50ºC. The research results obtained by the model mathematics to predict the optimum conditions for the recovery of barium sulfate crystals. The optimum condition for obtaining barium sulfate crystals is 0.3120 g with concentration of 25 ppm additive CaCl2, stirring speed 483.6364 rpm and time stirring 49.0909 minutes. While the acquisition of barium sulfate crystals 0.3072 gr with a concentration of 5 ppm additive MgCl2, agitation speed of 158.7879 rpm and mixing time 120 minutes. It can be seen that MgCl2 has the ability to additive controlling barium sulfate crystals is greater than the additive CaCl2
