The aim of the present research paper is to convert daily waste materials generated by human activity at Hail city into useful petroleum additives. In this respect, novel multifunctional corrosion inhibitors working as inhibitors and flow improvers for crude oil were prepared. Polyethylene terephthalate (PET) plastic waste is used in the production of corrosion inhibitors and flow improvers for petroleum crude oil. A multifunctional corrosion inhibitor for the SABIC carbon steel in corrosive seawater for application in the petroleum industry was manufactured using PET waste that was gathered, cleaned, and used as starting materials. The PET green recycling method takes place via the Abdel-Hameed green recycling reported method. In the first step, PET waste was reacted without a solvent with a diamine to form the diamino derivative of phthalic acid amide (PETAA), which was characterized by FT-IR, HNMR, and elemental analysis. In the presence of a catalyst, the used recycling method is a solvent-free green recycling process that is environmentally friendly. Chemical and electrochemical measurements were performed, and the effects of concentration and temperature were studied. The inhibition efficiency was found to increase with concentration. A maximum inhibition of 97% was obtained using 4000 ppm from the prepared PETAA inhibitor, while the efficiency decreased with temperature. Potentiodynamic polarization (PDP) data indicates the mixed-type nature of the used inhibitor. According to potentiodynamic polarization data, the inhibitor boosts polarization resistance and inhibition performance by adsorbing on the metal/electrolyte interface. The data from electrochemical impedance spectroscopy (EIS) show that the charge-transfer mechanism is the primary governing factor in the steel dissolution process. The size of the semicircle grows in direct proportion to the concentration of the inhibitor. The prepared additive acts as a flow improver (viscosity improvers and pour point depressants) for waxy crude oil, indicating that it can be used in the manufacturing of multifunctional inhibitors in the petroleum industry. The depression in the pour point temperatures depended on the concentration and composition of the additive prepared from the plastic waste collected from Hail city.
本研究论文的目的是将海勒市人类活动产生的日常废料转化为有用的石油添加剂。在这方面，制备了新型多功能缓蚀剂，其可作为原油的缓蚀剂和流动改进剂。聚对苯二甲酸乙二酯（PET）塑料废料被用于生产石油原油的缓蚀剂和流动改进剂。使用收集、清洗后的PET废料作为起始原料，制造了一种用于沙特基础工业公司碳钢在腐蚀性海水中的多功能缓蚀剂，该缓蚀剂应用于石油工业。PET绿色回收方法通过阿卜杜勒 - 哈米德绿色回收报告方法进行。第一步，PET废料在无溶剂条件下与二胺反应形成邻苯二甲酸酰胺的二氨基衍生物（PETAA），通过傅里叶变换红外光谱（FT - IR）、核磁共振氢谱（HNMR）和元素分析对其进行了表征。在催化剂存在下，所采用的回收方法是一种无溶剂的绿色回收过程，对环境友好。进行了化学和电化学测量，并研究了浓度和温度的影响。发现缓蚀效率随浓度增加而提高。使用制备的PETAA缓蚀剂4000 ppm时，最大缓蚀率达到97%，而效率随温度降低。动电位极化（PDP）数据表明所用缓蚀剂为混合型。根据动电位极化数据，缓蚀剂通过吸附在金属/电解质界面上提高极化电阻和缓蚀性能。电化学阻抗谱（EIS）数据表明电荷转移机制是钢溶解过程中的主要控制因素。半圆的大小与缓蚀剂浓度成正比。制备的添加剂可作为含蜡原油的流动改进剂（粘度改进剂和降凝剂），表明其可用于石油工业中多功能缓蚀剂的制造。降凝温度取决于从海勒市收集的塑料废料制备的添加剂的浓度和组成。
