The formation of incrustations is a serious problem with which industries have
to be driven, where training and injection waters are used, as well as flow
surfaces of heat exchangers, evaporators and cooling towers. [1] [2]. Carbonate,
CaCO3, is one of the most common scales, found in oil field wells and in surface
facilities [3]. In the search for a solution to this problem, several techniques have
been implemented in order to control the generation of these salts, one of them
is the use of various chemical species as antifouling.
In this work the behavior of a coumarin, as a calcium carbonate scale inhibitor,
was evaluated to the conditions of formation of the same in pipes, performing
different dosages in a brine rich in calcium carbonate with CO2 dosage and high
temperatures, Although coumarins are used especially in the medical field, it
was found that the chemical species evaluated has good inhibition efficiencies
(between 70 and 90%), reducing the formation of calcium carbonate crystals.
The evaluation of the corrosion products obtained was performed by X-ray
diffraction and scanning electron microscopy.
