The invention is an electrostatic coalescer testing apparatus for testing the ability of chemical additives to facilitate electrostatic coalescence of water in a water hydrocarbon-containing mixture. The apparatus includes: (a) a plurality of tubular containers for containing the water-hydrocarbon mixture, each of the tubular containers having one open end and one closed end, and made of a material not substantially electrically conductive; (b) a heating block/electrode having a plurality of tubular recesses therein, each of the tubular recesses for receipt of one of the tubular containers disposed closed-end down, the heating block/electrode comprising of a heat conducting and electrical current conducting material, for conducting heat to the tubular containers, and for applying an electrical potential across the water-hydrocarbon mixture; (c) a mixing blade/electrode member disposed within each of the tubular containers for mixing the water-hydrocarbon mixture with the chemical additive, and for applying an electrical potential to the water-hydrocarbon mixture; (d) a transformer means having two poles for applying an electrical potential to the two electrodes wherein; one pole is connected to the mixing blade/electrode; and one pole is connected to the heating block/electrode.
