Latest Patents

Guo is credited with 1 patent, titled “Method for In-Situ Remediation of Contaminated Soil Through Multi-Technology Coupling.” The method preheats contaminated soil using in-situ thermal conductive heating, followed by multiphase extraction. It then cycles through hot-steam injection, multiphase extraction, and injection of an oxidizing agent.

The associated system uses a heating well connected to a thermal conductive heating system, an injection well connected to an in-situ injection system, and an extraction well connected to a vacuum extraction system. Together, these components support soil preheating, delivery of hot steam and oxidizing agents, and extraction of contaminants. The invention describes combining these technologies to increase the removal rate of pollutants from organically contaminated soil.

Career Highlights

Guo’s listed patent focuses on in-situ remediation, allowing treatment to take place at the contaminated site. Its multi-step approach integrates heating, extraction, and oxidation rather than relying on a single remediation technique.

Collaborations

Guo’s listed coworkers include Jingwen Li and Yuru Sun. His company affiliation is Bceg Environment Remediation Co., Ltd.

Conclusion

Nan Guo’s patent presents a coupled approach to treating organically contaminated soil, combining thermal heating, multiphase extraction, and oxidizing-agent injection to improve pollutant removal.
