Role of surface forces in formation and mitigation of complex mineral scales using novel polymeric based inhibitors

在液体输送过程中，管道上不必要的物质沉积是一个复杂的、多阶段的发展过程，它受到界面过程的显著影响。它涉及动量、热质传递、化学动力学和材料科学等多门学科。主要驱动力是矿物的溶解度和这些矿物沉积过程中的吸引-排斥力的作用。从过饱和的水介质中结晶将自发地发生在系统中的非均质上，例如现有的沉淀物、设备表面和各种悬浮固体(粘土、沙子等)。结晶动力学依赖于离子从主体溶液到液-固界面的扩散。该过程包括：离子和分子在感兴趣的表面上的吸附；被吸附的物种在表面扩散到能量有利的生长位置；以及最终并入现有的晶格结构。对这些表面现象的破坏是许多成熟的缓解策略的基础，其中包括化学抑制和表面工程。减轻结晶污染的策略包括应用化学缓蚀剂和工程表面(涂层)。在这里，SLS化学公司提供的新型聚合物缓蚀剂将作为一种环境友好型缓蚀剂进行测试，这种新化学物质的性能也将得到详细研究。为了确定不同操作参数下的成核参数和结垢条件，通常采用定性的理论分析方法。有趣的是，人们对晶体间表面力的作用的研究非常有限。

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
