Publication number: 20240150642Abstract: Nano- and micro-particles (NMP) can be formed from an oil/water emulsion. The emulsion is made by mixing a liquid solvent, at least one surfactant, a particle-forming compound, and at least curing agent. If desired, pH control agents and viscosity enhancers can be added to the liquid solvent. The particle-forming compound and the curing agents are mixed together and form the oil phase in the emulsion and after curing, the particles are formed. The nano- and micro-particles can be used as proppant to enhance the conductivity of nano- and microfractures and fluid-loss-control additive for hydraulic fracturing operations.Type: ApplicationFiled: January 18, 2024Publication date: May 9, 2024Applicants: CNPC USA CORPORATION, Beijing Huamei, Inc., China National Petroleum CorporationInventors: Lijun Lin, Jiangshui Huang, Fuchen Liu, Lulu Song, Zhenzhou Yang, Yu Liu, Hanxiao Wang

Patent number: 9481839Abstract: A hot oxygen nozzle and uses thereof in a gasifier, the hot oxygen nozzle comprising an outer-ring spout, a middle-ring spout, an inner-ring spout, and a central spout all sequentially and coaxially disposed, and a cooling system; the gasifier is an entrained-flow gasifier provided with one or more nozzles on a certain plane or a plurality of planes at the top or on the periphery of the gasifier body. The nozzle has a simple structure and is easy to make and maintain. A fuel gas passage is disposed inside the nozzle. Oxygen can be heated by a combustion of fuel gas; and high-temperature and high-speed oxygen can directly ignite carbonaceous materials such as coal-water slurry and coke-oven gas. The present invention can be applied in a gasifier and then in the final process of synthesis gas preparation.Type: GrantFiled: November 26, 2013Date of Patent: November 1, 2016Assignees: PRAXAIR TECHNOLOGY, INC., EAST CHINA UNIVERSITY OF SCIENCE AND TECHNOLOGYInventors: Qinghua Guo, Tao Wang, Zhenghua Dai, Guangsuo Yu, Xin Gong, Fuchen Wang, Haifeng Liu, Yifei Wang, William J.

Patent number: 7862632Abstract: Disclosed is a multi-burner gasification reactor for gasification of slurry or pulverized hydrocarbon feed materials and industry applications thereof. Burners are disposed on the periphery or top of a gasification reactor vessel, wherein the side burners are at a small downward angle relative to the horizontal plane, which can prolong the life of refractory bricks. The operating pressure of the gasification reactor is 0.1˜12 MPa, and the operating temperature thereof is 1350° C.˜1700° C. The gasification reactor is applicable to a hot-wall lining as well as a cold-wall lining. The notable advantages of the gasification reactor are carbon conversion is high and can reach 99%, and the effective gas content is high; specific coal consumption and specific oxygen consumption are low; and it is applicable to a large coal gasification plant that processes above 3000 tons of coal per day.Type: GrantFiled: May 15, 2007Date of Patent: January 4, 2011Inventors: Zunhong Yu, Guangsuo Yu, Xin Gong, Fuchen Wang, Haifeng Liu, Zhenghua Dai, Yifei Wang, Weifeng Li, Qinfeng Liang, Xiaolei Guo, Xingjun Wang, Xueli Chen, Zhijie Zhou

Publication number: 20080073445Abstract: This invention relates to a kind of clustered nozzle for gasification or combustion and its industrial applications. The clustered nozzle comprises a body case (5) and a plurality of nozzles (11) in the body case (5). The nozzle (11) includes an outer cannula (3) and an inner cannula (4) inside the outer cannula (3), a lower tubesheet (6), an upper tubesheet (7) and a cooling chamber (13). Compared with traditional coaxial double-pipe nozzles (e.g., dual-channel nozzles, triple-channel nozzles and multi-channel nozzles), the clustered nozzle for gasification or combustion has the following advantages: the length of combustion flame is shorter and the shape of flame is approximately rectangular, which help to protect the lower firebricks of the gasifier, thus prolonging their working life; the distribution of the residence time is narrower, which helps to increase the conversion rate of carbon; and the nozzle is properly-structured, which helps to prolong its working life.Type: ApplicationFiled: August 15, 2007Publication date: March 27, 2008Inventors: Zunhong YU, Haifeng Liu, Weifeng Li, Zhenghua Dai, Xueli Chen, Guangsuo Yu, Fuchen Wang, Xin Gong
