Abstract
The present invention relates to an apparatus for salt precipitation and scaling tests, which comprises two reagent storage tanks (), a reagent mixing module (), induction period measurement modules (), an ultrasound-assisted precipitation module () and a scaling module with heat exchanger (). From the apparatus, it is possible to carry out tests with the purpose of investigating the influence of parameters such as flow rate, temperature and concentration on salt precipitation and scaling. It is further possible to carry out tests under the action of ultrasound, since it promotes acceleration of chemical reactions.
