Patent number: 11948284Abstract: The present invention belongs to the technical field of petroleum exploitation engineering, and discloses a 3D modeling method for pore-filling hydrate sediment based on a CT image. Indoor remolding rock cores or in situ site rock cores without hydrate can be scanned by CT; a sediment matrix image stack and a pore image stack are obtained by gray threshold segmentation; then, a series of pore-filling hydrate image stacks with different saturations are constructed through image morphological processing of the pore image stack such as erosion, dilation and image subtraction operation; and a series of digital rock core image stacks of the pore-filling hydrate sediment with different saturations are formed through image subtraction operation and splicing operation to provide a relatively real 3D model for the numerical simulation work of the basic physical properties of a reservoir of natural gas hydrate.Type: GrantFiled: July 23, 2020Date of Patent: April 2, 2024Assignee: DALIAN UNIVERSITY OF TECHNOLOGYInventors: Yongchen Song, Yanghui Li, Peng Wu, Xiang Sun, Weiguo Liu, Jiafei Zhao, Mingjun Yang, Lei Yang, Zheng Ling

Patent number: 11939238Abstract: The present disclosure provides an apparatus and a method for hydrate-based wastewater treatment and cold storage. The apparatus for hydrate-based wastewater treatment and cold storage includes a water chilling unit, a hydrate-based cold storage tank, an airflow disturbance device, a water layer positioning system, a spraying system, a suction filtration system, a heat exchange system, and a system monitoring device. The water chilling unit provides a secondary refrigerant at a low temperature. The secondary refrigerant flows through an evaporator coil in the hydrate-based cold storage tank for heat exchange. The airflow disturbance device induces hydrate nucleation. The water layer positioning system positions a contact surface between a water layer and a hydrate former after hydrate decomposition to facilitate drawing and separation of the treated upper water layer. The spraying system and the suction filtration system enhance the solid-liquid separation efficiency to improve the removal rate of pollutants.Type: GrantFiled: May 15, 2023Date of Patent: March 26, 2024Assignee: DALIAN UNIVERSITY OF TECHNOLOGYInventors: Lunxiang Zhang, Yongchen Song, Xiaodong Wu, Jiazhu Bao, Chuanxiao Cheng, Zheng Ling, Jie Wang, Fan Wang, Yu Liu, Lei Yang, Mingjun Yang, Yanghui Li, Peng Wu

Patent number: 11926538Abstract: The present disclosure relates to the technical field of wastewater treatment, and provides a wastewater treatment method and apparatus based on hydrate-based water vapor adsorption. The apparatus includes a wastewater evaporation zone, a hydrate formation zone, a hydrate decomposition zone, and a data acquisition and control system. Rising water vapor and condensed water formed during evaporation of wastewater at normal temperature react with a hydrate former on a cooling wall surface to form a hydrate, continuous evaporation of the wastewater is promoted, the hydrate is scraped off to a collecting zone below by a scraper after being formed, and the hydrate is decomposed into fresh water, thereby realizing wastewater treatment. The present disclosure provides a method for treating complex wastewater containing a plurality of pollutants, where water vapor is consumed to form the hydrate to promote wastewater evaporation, and water obtained from the decomposition does not contain pollutants theoretically.Type: GrantFiled: May 10, 2023Date of Patent: March 12, 2024Assignee: DALIAN UNIVERSITY OF TECHNOLOGYInventors: Yongchen Song, Lunxiang Zhang, Huilian Sun, Zheng Ling, Jiafei Zhao, Lingjie Sun, Lei Yang, Mingjun Yang, Yu Liu, Weiguo Liu, Yanghui Li, Xiang Sun, Lanlan Jiang
