Development of Novel Nanopolymers and Nanofibers as Iron Sulfide Scale Inhibitors in Oil Production

硫化氢是石油天然气工业和造纸工业中常见的污染物。硫化氢气体的反应性导致硫化铁垢的堆积。矿物结垢是石油和天然气生产中一个严重且昂贵的问题。管道内表面的硫化铁结垢是含硫原油油井生产商面临的一个严重的流量保证问题，这是加拿大常规石油生产商面临的重大挑战。通常，使用机械和化学方法来**减轻FeS垢。机械除垢只在容易接近的地区是可行的。因此，为了预防、控制和减少形成的FeS矿床，必须进行化学**处理。使用**盐酸的酸化处理是去除FeS沉淀物最常用的程序。然而，副产物硫化氢的产生，加速系统腐蚀的潜力，以及它对黄铁矿等更稳定形式的铁硫化物的低效，限制了它的应用。其他治疗方法使用铁络合剂。但是，铁络合剂在防止硫化铁垢形成方面的选择性很差，这导致应用变得**在经济上不可行。因此，目前工业产品开发需要创新的**方法来有效控制高盐水系统中的硫化铁结垢。因此，在该提案中，我们建议**开发创新的高功能聚合物材料(超支化聚合物和纳米纤维)**以去除硫化铁沉淀物。

Hydrogen sulfide is a common contaminant in the oil and gas industry as well as in the paper industry. The**reactive nature of the hydrogen sulfide gas causes accumulation of iron sulfide scale. Mineral scale formation is**a serious and expensive problem in oil and gas production. Iron sulfide scale formation on the inner surfaces of**the pipeline is a serious flow assurance problem faced by sour crude oil well producers, which is a major**challenge for conventional oil producers in Canada. Commonly, mechanical and chemical methods are used to**mitigate FeS scale. Mechanical scaling removal is only feasible in easily accessible areas. Therefore, chemical**treatment is necessary to prevent, control and reduce formed FeS deposits. Acidizing treatment using**hydrochloric acid is the most common procedure utilized for FeS deposits removal. However, the generation**of H2S by-product, the potential to accelerate corrosion in the system and its inefficiency to more stable forms**of iron sulfides such as pyrite, limits its application. Other treatment uses iron chelators. But, iron chelators**has poor selectivity towards preventing iron sulfide scaling formation, which leads the applications to become**economically unfeasible. Therefore, there is a current industrial product development demand for innovative**ways to efficiently control iron sulfide scaling on high brine systems. Therefore, in the proposal, we propose**the development of innovation highly functional polymer materials (hyperbranched polymers and nanofibers)**for the removal of the iron sulfide deposits.
