Patent number: 10941784Abstract: A centrifugal pump (1) includes a pump casing and a shaft (11) which is rotatably mounted therein and on which an impeller (10), for delivering fluid, is arranged rotationally fixed. A cartridge shaft seal (13) is arranged between the shaft (11) and an opening (16) of the casing, through which opening the shaft (11) is led. The cartridge shaft seal (13) includes a sleeve (22) which surrounds the shaft (11) at least in the region of the opening 16 and which is connected to the shaft (11) releasably and rotationally fixed, by way of a clamping device (29) which is arranged on the outer side of the sleeve (22). The clamping device (29) includes clamping jaws (32) which only engage on the outer side of the sleeve (22) and non-positively connect the sleeve (22) to the shaft (11).Type: GrantFiled: August 7, 2018Date of Patent: March 9, 2021Assignee: GRUNDFOS HOLDING A/SInventors: Erik Bundesen Svarre, John Frigård Nielsen, Lars Skov

Patent number: 8333884Abstract: Partial conversion hydrocracking process comprising the steps of (a) hydrotreating a hydrocarbon feedstock with a hydrogen-rich gas to produce a hydrotreated effluent stream comprising a liquid/vapor mixture and separating the liquid/vapor mixture into a liquid phase and a vapor phase, and (b) separating the liquid phase into a controlled liquid portion and an excess liquid portion, and (c) combining the vapor phase with the excess liquid portion to form a vapor plus liquid portion, and (d) separating an FCC feed-containing fraction from the controlled liquid portion and simultaneously hydrocracking the vapor plus liquid portion to produce a diesel-containing fraction, or hydrocracking the controlled liquid portion to produce a diesel-containing fraction and simultaneously separating a FCC feed-containing fraction from the vapor plus liquid portion. The invention also includes an apparatus for carrying out the partial conversion hydrocracking process.Type: GrantFiled: November 23, 2009Date of Patent: December 18, 2012Assignee: Haldor Topsoe A/SInventors: Michael Glenn Hunter, Angelica Hidalgo Vivas, Lars Skov Jensen, Gordon Gongngai Low
