improvement of cohesive interactions between calcium carbonate particles using a green scale inhibitor

Higher operating costs and lower production rates in the up and downstream oil industry are commonly reported as the consequence of mineral scale formation. subsequently, scale inhibitors (si) are generally known as an efficient approach to overcome this severe problem. however, the employment of some sis is hazardous to the environment due to their chemical structures and the presence of some functional groups. therefore, the utilization of green sis has been highly recommended. in this study, folic acid as a green si was investigated from a theoretical perspective, although some preliminary experiments, i.e., high-temperature static tests and contact angle measurements, were done. the results revealed that folic acid could inhibit calcite precipitation through the lewis acid-base interaction energies. moreover, folic acid could optimally retard calcite particles from getting aggregated and further precipitated at the dose of 450 ppm.
