Unnecessary material deposition on the conduits during the transport of a liquid is a complex, multistage development, which is significantly influenced by interfacial processes. It relates to many subjects such as momentum, heat and mass transfer, chemical kinetics, and material science. The principle driving force is mineral solubility and role of attractive-repulsive forces during the deposition of these minerals. Crystallization from a supersaturated aqueous medium will occur spontaneously on heterogeneities in the system, such as existing precipitates, equipment surfaces and miscellaneous suspended solids (clays, sands, etc.). Crystallization kinetics depends on ion diffusion from the bulk solution to a liquid-solid interface. The process ensues as: adsorption of ions and molecules onto a surface of interest; surface diffusion of adsorbed species onto energetically favorable growth positions; and eventual incorporation into existing crystal lattice structure. Disruptions of these surface phenomena are the basis for many well-established mitigation strategies, which includes chemical inhibition and surface engineering. Mitigation strategies for crystallization fouling include the application of chemical inhibitors and engineered surfaces (coatings). Here, the novel polymeric inhibitor, available with SLS Chemical Inc., will be tested as an environment friendly inhibitor and the performance of this new chemical will also be investigated in detail. Often, qualitative theoretical analysis is proposed to identify nucleation parameters and fouling conditions under different operating parameters. Interestingly, very limited attention has been given to investigate the role of surface forces between crystals
