<p>A method for testing the effectiveness and performance of chemicals in a scale-forming liquid, in particular scale inhibitors, comprising the steps of supplying (1,2) the liquid through a test circuit (11), measuring (5) and recording (7) continuously the inlet pressure to a test circuit (11) during a predetermined time, adding (3) subsequently the chemicals to be tested to the liquid, and at each addition measuring (5) and recording (7) continuously the pressure to the test circuit (11). A method for testing chemicals such as scale removers in a scale-forming liquid, comprising the steps of supplying (1,2) the liquid through a test circuit (11) and after scale has been deposited from the liquid, adding (3) suitable chemicals to the test circuit (11) and continuously measuring (5) and recording (7) the pressure decrease in the test circuit (11). An apparatus for carrying out the above-mentioned methods.</p> |
