In one aspect, the invention can be a heat exchanger comprising: a shell forming a cavity, the shell comprising an inlet for introducing a shell-side fluid into the cavity and an outlet for allowing the shell-side fluid to exit the cavity; a tube bundle for carrying a tube-side fluid, the tube bundle located in the cavity along a longitudinal axis; at least one stabilizing plate positioned within the cavity and arranged in a substantially transverse orientation, the stabilizing plate comprising a lattice structure having openings, wherein tubes of the tube bundle extend through the openings; and wherein the openings of the lattice structure are sized and shaped so that the tubes contact the lattice structure and a portion of the openings remain unobstructed by the tubes, thereby allowing axial flow of the shell-side fluid through the stabilizing plate.Type: ApplicationFiled: May 6, 2010Publication date: November 11, 2010Inventors: Krishna P. Singh, Ranga Nadig

Patent number: 7793708Abstract: A tube support device is used with tube bundle devices such as heat exchangers or, condensers with in-line tube arrangements (rectangular tube configuration) to mitigate the possibility of tube damage from flow-induced vibration in the tube bundle. The tube support comprises an elongated member or strip which is intended to be inserted in a tube lane between the tubes of the tube bundle. Raised-tube-engaging zones which include transverse, arcuate tube-receiving saddles are disposed along the length of the strip at successive longitudinal locations corresponding to the tube positions in the bundle. These tube-engaging zones extend laterally out, away from the medial plane of the strip, so that the saddles receive and closely hold the tubes on opposite sides of the tube lane.Type: GrantFiled: May 13, 2005Date of Patent: September 14, 2010Assignee: ExxonMobil Research & Engineering CompanyInventors: Amar S. Wanni, Marciano Madrid Calanog, Thomas M. Rudy, Malcolm D. Keen

Patent number: 7779901Abstract: A debris catching device for downhole milling features modular debris receptacles that are held in the housing in a manner that facilitates stacking and a generally undulating flow path to facilitate dropping of the debris into the receptacles as the remaining fluid travels up the tool for ultimate screening before the fluid exits the tool to flow up to the surface or in a reverse circulation pattern back to the mill below the debris catcher. The modules can also be aligned with flapper valves at the top of each module to prevent debris in the tool from falling to the mill if circulation is turned off. The mill is configured to have an off-center return path preferably as large as the passage through the mill body to aid circulation and cutting performance.Type: GrantFiled: March 18, 2009Date of Patent: August 24, 2010Assignee: Baker Hughes IncorporatedInventors: John P. Davis, James S. Trahan, Paul L. Connell
