The main aim of this work is to determine performance ranking of asphaltene controlling chemical additives using Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method. The performance of four chemicals namely; Cocamide Diethanolamide (CDEA), Dodecyl Benzene Sulphonic Acid (DBSA), Salicylic Acid, and Toluene were evaluated on crude oil of Pakistani origin. The performance of chemical additives was evaluated before and after the initiation of asphaltene precipitation as chemical performance during pre-treatment and post-treatment stage respectively. TOPSIS method was used to incorporate different parameter of experiment as criteria and further the weight of criteria importance were altered to yield rankings of chemicals under different scenarios. Three cases were developed to implement TOPSIS method. For case – 1 and Case – 2, generally, DBSA found to be the best additive while for case – 3 Salicylic acid and Toluene was proved to be rank 1 additive. The alteration of weight importance of criteria affects the chemical additive ranking. This research work highlighted the importance of decision making process for the selection of chemical additives considering the desired specific role of chemical additive to be used for the prevention and mitigation of asphaltene deposition in crude oil.

利用 TOPSIS 方法中重量标准重要性的战略敏感性选择最佳的原油控制化学添加剂


这项工作的主要目的是使用理想解决方案相似度优先顺序技术 (TOPSIS) 方法确定沥青质控制化学添加剂的性能排名。四种化学品的性能分别是；对源自巴基斯坦的原油中的椰油酰胺二乙醇酰胺 (CDEA)、十二烷基苯磺酸 (DBSA)、水杨酸和甲苯进行了评估。化学添加剂的性能在沥青质沉淀开始之前和之后分别作为预处理和后处理阶段的化学性能进行评价。采用TOPSIS方法，将不同的实验参数作为标准，并进一步改变标准重要性的权重，以得出不同场景下化学品的产量排名。开发了三个案例来实施 TOPSIS 方法。对于案例 1 和案例 2，一般来说，DBSA 被认为是最好的添加剂，而对于案例 3，水杨酸和甲苯被证明是 1 级添加剂。标准权重重要性的改变会影响化学添加剂的排名。这项研究工作强调了选择化学添加剂决策过程的重要性，考虑到化学添加剂在预防和减轻原油中沥青质沉积方面所需的具体作用。
