Abstract

Joule and photothermal heating offer promising avenues for enhancing oil recovery, desorption, and reusability by reducing the viscosity of highly viscous oils, thereby facilitating their mobility on sorbent surface. This study developed a heatable reduced graphene oxide nanoribbon (r-GONR)-coated polyvinylidene fluoride (PVDF) oil sorbent to address these viscosity challenges. The application of heating increased oil desorption by approximately 50%, significantly outperforming the conventional PVDF mat. The r-GONR sorbent, leveraging the photothermal effect, demonstrated exceptional reusability, maintaining 40% oil desorption efficiency up to the 10th cycle. Furthermore, its high oil desorption and reusability translated into considerable economic benefits, with a revenue potential of 6.4–29.0 $/m2, alongside significant environmental impact reduction. This study introduces a novel, sustainable approach to oil desorption and reuse, underscoring the practical applications of heatable materials in enhancing oil recovery.

焦耳和光热加热技术用于石油解吸的技术经济可行性和环境影响分析

焦耳加热和光热加热可降低高粘度油类的粘度，从而促进其在吸油剂表面的流动性，为提高石油采收率、解吸率和再利用率提供了前景广阔的途径。本研究开发了一种可加热的还原氧化石墨烯纳米带（r-GONR）涂层聚偏氟乙烯（PVDF）吸油剂，以解决这些粘度难题。通过加热，油的解吸率提高了约 50%，明显优于传统的聚偏二氟乙烯（PVDF）吸油垫。利用光热效应的 r-GONR 吸附剂表现出卓越的重复利用率，在第 10 次循环中仍能保持 40% 的油解吸效率。此外，这种吸油剂的高脱附效率和可重复使用性还带来了可观的经济效益，其收入潜力为 6.4-29.0 美元/平方米，同时还显著减少了对环境的影响。这项研究介绍了一种新型、可持续的石油解吸和再利用方法，强调了可加热材料在提高石油采收率方面的实际应用。
