Patent number: 8969423Abstract: In a process for the production of substitute natural gas, a feed gas is provided to a first and/or second and/or subsequent bulk methanator. The feed gas is subjected to methanation in the presence of a suitable catalyst. An at least partially reacted stream from the first bulk methanator is removed and supplied to the second and/or subsequent bulk methanator where it is subjected to further methanation. A product stream from the final bulk methanator is passed to a trim methanator train where it is subjected to further methanation. A recycle stream is removed downstream of the first, second or subsequent bulk methanator, and, in any order, passed through a compressor, subjected to cooling and then supplied to a trim and/or recycle methanator for further methanation before being recycled to the first and/or second and/or subsequent methanator.Type: GrantFiled: June 27, 2011Date of Patent: March 3, 2015Assignee: Davy Process Technology LimitedInventors: Philip Henry Donald Eastland, Jonathan Geoffrey Gavin, David Andrew Walker

Patent number: 8101142Abstract: A reactor system, plant and a process for the production of methanol from synthesis gas is described in which the reactor system comprises: (a) a first reactor adapted to be maintained under methanol synthesis conditions having inlet means for supply of synthesis gas and outlet means for recovery of a first methanol-containing stream, said first reactor being charged with a first volume of a methanol synthesis catalyst through which the synthesis gas flows and on which in use, partial conversion of the synthesis gas to a product gas mixture comprising methanol and un-reacted synthesis gas will occur adiabatically; and (b) a second reactor adapted to be maintained under methanol synthesis conditions having inlet means for supply of the gaseous first methanol-containing stream, outlet means for recovery of a second methanol-containing stream and cooling means, said second reactor being charged with a second volume of a methanol synthesis catalyst through which the gaseous first methanol-containing stream flowsType: GrantFiled: May 30, 2002Date of Patent: January 24, 2012Assignee: Davy Process Technology LimitedInventor: Philip Henry Donald Eastland

Patent number: 6905592Abstract: The invention relates to: a process for the desulphurization of feed streams comprising: supplying a hot process stream to a lead catalyst bed (8) comprising a first sulphur-removing catalyst and a second sulphur-removing catalyst under conditions whereby sulphur is removed from the process stream by the first sulphur-removing catalyst and said second sulphur-removing catalyst does not effectively remove sulphur from the stream at the operating temperature of the lead catalyst bed for the duration of the bed's life; collecting a hot partially sulphur-depleted stream from the lead catalyst bed and cooling said stream; passing said cooled stream through a lag catalyst bed (11) comprising the first sulphur-removing catalyst and the second sulphur-removing catalyst under conditions whereby sulphur is removed from the process stream by the second sulphur-removing catalyst and said first sulphur-removing catalyst removes sulphur less efficiently from the stream at the operating temperature of the lag catalyst bed;Type: GrantFiled: May 30, 2002Date of Patent: June 14, 2005Inventors: Roger Bence, Stephen Caig Littlewood, Philip Henry Donald Eastland
