Patent number: 6805550Abstract: The method of the invention concerns operation of a furnace utilizing a hydrogen-rich gas as furnace fuel. The furnace has multiplicity of burners for burning fuel supplied thereto. The method comprises providing ignition means for lighting a flame at at least one burner of the multiplicity of burners. An oxygen-containing gas and a combustible gas comprising a hydrocarbon gas are supplied to each of the multiplicity of burners in amounts capable of forming an ignitable mixture. A flame is ignited at the predetermined one burner which is then allowed to propagate from the at least one predetermined burner to the other burners of the multiplicity of burners. Then the composition of the combustible gas is altered over a period of time so as to replace at least a major part of the hydrocarbon gas by a hydrogen-rich gas until a hydrogen flame is established at each of the multiplicity of burners.Type: GrantFiled: May 16, 2003Date of Patent: October 19, 2004Assignee: Davy Process Technology LimitedInventors: Michael Hilton, John Wilson Kippax

Patent number: 6609562Abstract: A heat exchanger comprises a plurality of first heat exchange tubes extending through the exchanger, and through a plurality of laterally extending heat exchanger chambers, each chamber having at least one entry from a first chamber and at least one exit to a second axially adjacent chamber, and each chamber having a plurality of transverse interconnecting zones, each of which is defined by at least two of said tubes, and at least one first zone has an entry to said first chamber and at least one second zone, different from said first zone, has an exit to said second chamber. Also included is a vessel for mixing or distributing streams of a first fluid passing axially from an upstream to a downstream location, which comprises transverse baffles across said vessel in at least two successive rows, which rows of baffles define an open transverse chamber, the baffles in successive rows having a different spatial distribution across the vessel.Type: GrantFiled: December 10, 2001Date of Patent: August 26, 2003Assignees: BP Exploration Operating Company Limited, Kvaerner Process Technology LimitedInventors: Josephus Johannes Helena Maria Font-Freide, John Wilson Kippax, Geoffrey Gerald Weedon, William Terence Woodfin
