” These consist of THz dating, THz expedition, unrefined oil identification, crude oil emulsion demulsification process, pattern shifts of oil-water two-phase flow, disaggregation of unrefined oil in a magnetic field, PM2.5 monitoring, and grading,” explains Professor Kun Zhao, who works at the Beijing Key Laboratory of Optical Detection Technology for Oil and Gas at the China University of Petroleum (Beijing), China.Researchers comprehensively examine the application of terahertz spectroscopy for the characterization and examination of oil shale. THz Spectroscopy in Oil Shale ResearchIn the evaluation article, the group summarizes the applications of THz spectroscopy in defining anisotropy, natural distribution, fingerprint spectrum of kerogen, oil yield, pyrolysis process, and THz wave absorption of oil shale. The scientists likewise recognized direct evaluation of the oil yield without pyrolysis due to the strong dependence of the anisotropic THz criteria on the oil yield to prevent ecological pollution.Challenges and Future Prospects” Although the essential progress of THz wave characterization of oil shale has been accomplished, the research study breadth and depth are still lacking, and many obstacles require to be fixed,” highlights Prof. Zhao.
