Patent number: 10408542Abstract: The invention relates to a heat exchange device comprising a channel wall defining a flow channel with an inlet for receiving a gas flow. The device further comprises one or more heat exchange surfaces positioned inside the flow channel creating different parallel flow paths for the gas flow through the flow channel, at least one of the heat exchange surfaces embedding one or more flow paths for a fluid heat exchange medium. The one or more deflection elements are positioned inside the flow channel and are attached to the channel wall to deflect the gas flow away from the channel wall.Type: GrantFiled: May 7, 2015Date of Patent: September 10, 2019Assignee: Air Products and Chemicals, Inc.Inventors: Alfons Heitmann, Joachim Papendick, Eckhard Friese, Gerhard Johan Van Elburg, Unai Jauregi, Mohammad Behzad

Publication number: 20140090805Abstract: A method and a rapper device for cleaning a heat exchange surface in a pressure vessel. The rapper device comprises a striker rod which has one end contacting the heat exchange surface in the pressure vessel and one end projecting out of the pressure vessel via a passage opening. The rapper device also comprises an impacting device for impacting the projecting end of the striker rod. A section of the striker rod is slideably supported in a pressure chamber adjacent the passage opening. The pressure chamber is connected to a sealing gas supply maintaining the pressure in the pressure chamber at a higher level than the pressure in the pressure vessel. A bellows defines a pressure chamber around at least a section of the striker rod.Type: ApplicationFiled: December 2, 2013Publication date: April 3, 2014Applicant: Shell Oil CompanyInventors: Alfons HEITMANN, Thomas Paul VON KOSSAK-GLOWCZEWSKI

Patent number: 8656567Abstract: A rapper device for cleaning a heat exchange surface in a pressure vessel by transmitting impact energy. The rapper device includes a striker and an impacting device for impacting the striker which has one end contacting the heat exchange surface in the pressure vessel. The striker includes a piston section having a piston rod projecting out of the pressure vessel via a passage opening in line with the impacting device. A piston head is slideable within a piston chamber in line with the passage opening. The piston chamber is operatively connected to a sealing gas supply. The piston head is a separate part with an aperture. The piston rod runs through the aperture, e.g., in a slideable arrangement.Type: GrantFiled: December 1, 2009Date of Patent: February 25, 2014Assignee: Shell Oil CompanyInventors: Alfons Heitmann, Uwe Herwig, Thomas Paul Von Kossak-Glowczewski
