Publication number: 20230235954Abstract: The present disclosure provides a system and method of efficiently designing a compact and modularized midscale liquefied natural gas production train. The train includes Natural Gas Pretreatment and Natural Gas Liquefaction sections designed in a unique way that reduces footprint, capital and operating cost, and overall project schedule. The train is configured into a framed compact multi-level structure with air coolers on the top level and process equipment underneath, which results in significant reduction in footprint compared to conventional stick-built design and significant reduction in footprint compared to conventional modularized design.Type: ApplicationFiled: January 21, 2022Publication date: July 27, 2023Applicant: TECHNIP ENERGIES FRANCEInventors: Rajeev NANDA, Terence Ashley SMITHIES, Jichuan HU, Jagdish J.

Patent number: 10139331Abstract: A filtration membrane fouling index measuring method including: (a) serially connecting two filtration membranes having the same membrane properties, and sequentially passing influent water therethrough; (b) measuring the flow volume that has passed through the first of the filtration membranes; (c) measuring the flow volume that has passed through the second of the filtration membranes; (d) measuring the cumulative pass-through volume that has passed through the first or the second filtration membrane; and (e) determining the fouling index of the filtration membrane, based on the flow volume that has passed through the first filtration membrane, the flow volume that has passed through the second filtration membrane and the cumulative pass-through volume. The method eliminates pore-blocking-induced measurement errors that occur with measurement methods involving Modified Fouling Index which is a fouling index for filtration membranes.Type: GrantFiled: December 5, 2013Date of Patent: November 27, 2018Assignee: DOOSAN HEAVY INDUSTRIES & CONSTRUCTION CO., LTD.Inventors: Seung Kwan Hong, Young Gil Ju, Jung Won Kim, Yong Xun Jin

Publication number: 20180150777Abstract: A global construction business management apparatus and a global construction business management system using the same. The global construction business management apparatus includes: an electric manual unit: deriving a task hierarchy in life stages to include a ‘plan and program stage’, a ‘design stage’, a ‘construction order and contract stage’, a ‘construction stage’, and an ‘operation and maintenance stage’ based on business process breakdown structure (BPS) information; providing to a responsible entity information required for performing a task; and providing performed task information to any one of the responsible entity, a revising entity, or an assigning entity; and a BPS mapping unit providing visualized information so that a temporal flow of the task hierarchy in life can be easily comprehended. Accordingly, an i-PgMIS is applied to a global construction project and used for various businesses by improving the i-PgMIS that is limited to an urban regeneration business.Type: ApplicationFiled: April 18, 2017Publication date: May 31, 2018Inventors: Sang-Won HAN, Yong-Woon CHA, Zheng Xun JIN, Jin-Ho JUNG, Chang-Taek HYUN, Su-Sang LIM, You-Sang YOON, Hyun-Jong LEE

Patent number: 9772455Abstract: The present invention relates to a universal optical fiber connector including a hot-melt end connector assembly, a heat-shrinkable sleeve and a protective shell for the heat-shrinkable sleeve. The assembly further comprises the main body of the hot-melt end, and a ceramic ferrule, a wedge for the ceramic ferrule and a pre-embedded optical fiber passing through the main body. The tail end of the protective shell for the heat-shrinkable sleeve is connected with an optical fiber locking device for the locking of the optical fiber; the locking device and the protective shell for the heat-shrinkable sleeve are separately configured. The present invention is applicable to optical fibers of different sizes and can improve the tensile properties of the optical fiber connector, and the protective shell for the heat-shrinkable sleeve can be volume-produced with the same mould instead of being produced independently for each type, so as to improve the production efficiency.Type: GrantFiled: October 27, 2015Date of Patent: September 26, 2017Assignee: INNO INSTRUMENT (CHINA) INC.Inventors: Yuzhong Zhang, Xun Jin

Patent number: 6176331Abstract: A bearing seal for earth boring bits is disclosed. A supporting ring is located in a groove formed in the earth boring bit. An annular cavity between the outer circumference of the supporting ring and the bottom of the groove is connected with the outside. An O-ring made of rubber is provided in an annular space defined by the sidewalls of the groove, the inner circumference of the supporting ring and the cylindrical surface of the bearing shaft of the head section to form a seal comprising a radial and axial seal. Compressive deformation of the O-ring does not depend on the eccentric rotation of the cone. Therefore, the working life of the seal is increased and the compressive deformation is decreased, thus facilitating use at high rotating speeds.Type: GrantFiled: November 30, 1998Date of Patent: January 23, 2001Assignee: Kingdream Public Ltd., Co.Inventors: Zhi Xun Jin, Xian Zhong Qiu, Feng Shou Xia, Ai Jun Li
