Patent number: 11946007Abstract: A natural gas separation and purification and mercury collection system for oil and gas wells includes a cyclone separator, a condensation purification and separation mechanism, pressure buffer mechanisms, mercury collection and separation mechanisms, and natural gas storage tanks. An inlet end of the cyclone separator is communicated with an external gas source through a pressure buffer mechanism, and an outlet end of the cyclone separator is communicated with the condensation purification and separation mechanism through a pressure buffer mechanism. The condensation purification and separation mechanism is communicated with the mercury collection and separation mechanism through a pressure buffer mechanism. The mercury collection and separation mechanism is communicated with the natural gas storage tank through a guide tube. A method of use of the natural gas separation and purification and mercury collection system includes gas collection, gas purification, mercury separation, and mercury analysis.Type: GrantFiled: November 24, 2023Date of Patent: April 2, 2024Assignee: Peking UniversityInventors: Quanyou Liu, Pengpeng Li, Jiarun Liu

Patent number: 11950484Abstract: A display panel includes a display layer, a photosensitive layer and an infrared mask. The display layer is configured to display an image, the display layer has light-transmitting portions, and the light-transmitting portions are configured to transmit infrared light. The photosensitive layer is disposed on a side of the display layer. The infrared mask is disposed on a side of the photosensitive layer proximate to the display layer, the infrared mask has hollowed-out regions, the hollowed-out regions are configured to make the infrared mask have a preset pattern, and a region in the infrared mask except the hollowed-out regions is configured to prevent transmission of the infrared light. The photosensitive layer is configured to receive infrared light passing though the hollowed-out regions and the light-transmitting portions, and convert the infrared light into an image signal.Type: GrantFiled: July 23, 2020Date of Patent: April 2, 2024Assignee: BOE TECHNOLOGY GROUP CO., LTD.Inventors: Pengpeng Wang, Haisheng Wang, Xiaoliang Ding, Yangbing Li, Xueyou Cao, Ping Zhang, Likai Deng, Yubo Wang

Patent number: 11841304Abstract: A device and method for testing an effective diffusion coefficient of helium in helium-bearing natural gas solves the problem that there is currently no systematic method or supporting experimental device to quantitatively characterize the diffusion behavior of helium in helium-bearing natural gas. The device includes a diffusion system and a gas sampling and analysis system. The diffusion system includes an upstream diffusion chamber, a downstream diffusion chamber, and a true triaxial apparatus, and is configured to simulate a gas diffusion process. The gas sampling and analysis system includes an upstream gas sample retention chamber, a downstream gas sample retention chamber, and a chromatographic analyzer, and is configured to sample a diffusing gas and analyze composition of the gas. By performing diffusion process simulation, gas sampling and analysis, and data calculation and fitting, the effective diffusion coefficient of helium in the helium-bearing natural gas is finally acquired.Type: GrantFiled: July 19, 2023Date of Patent: December 12, 2023Assignee: Peking UniversityInventors: Quanyou Liu, Pengpeng Li, Yu Gao
