Dynamic scale loop testing is an industry standard test to evaluate the performance of scale inhibitors under specific temperatures and pressures in a synthetic brine system. The brine is split into the anion and cation solutions and pumped separately though heated coils into the oven before mixing together in the scaling loop / coil.

Typically, blank tests are carried out in the absence of inhibitor to establish a blank scaling run time. The scale inhibitor is then dosed into the anion brine and run at a specific concentration(s), followed by another blank run to show the scale will again form in the absence of any inhibitor. The Differential scale loop is very versatile and the test conditions can be adapted to customer requirements.
