The heat exchanger as recited in claim 10, wherein the circumferential seal includes a flexible element which extends between the baffle and the shell.ġ2. The heat exchanger as recited in claim 1, wherein a circumferential seal is associated with each of the plurality of baffles.ġ1. The heat exchanger as recited in claim 1, wherein the plurality of baffles includes both shield style baffles and wing style baffles which are arranged in alternating pattern.ġ0. The heat exchanger as recited in claim 1, further including a second shroud distributor having at least one angled cut formed in an end thereof and arranged and configured to direct feed gas flow from the internal chamber to the feed gas outlet.ĩ. The heat exchanger as recited in claim 1, wherein the at least one angled cut formed in the end of the at least one shroud distributer is formed at an angle of 10-30 degrees.Ĩ. The heat exchanger as recited in claim 5, wherein the shroud distributor further includes a shield style baffle having a circumferential sealing element.ħ. The heat exchanger as recited in claim 4, wherein the shroud distributor includes a donut style baffle having a central window area.Ħ. The heat exchanger as recited in claim 1, wherein the at least one shroud distributor includes at least one circular baffle.ĥ. The heat exchanger as recited in claim 2, the first shroud distributor has two angled cuts formed in an end thereof for distributing the flow of feed gas.Ĥ. The heat exchanger as recited in claim 1, wherein two feed gas inlets and two feed gas outlets are formed in the outer wall of the shell.ģ. A shell and tube heat exchanger comprising: an elongated cylindrical shell that defines a longitudinal axis for the heat exchanger and an internal chamber, the shell having at least one feed gas inlet and feed gas outlet formed in an outer wall for allowing a feed gas to enter and exit the internal chamber at least one tube sheet associated with an end of the elongated shell a plurality of circular baffles longitudinally spaced apart within the internal chamber of the shell for redirecting feed gas flow within the internal chamber a tube bundle which includes a plurality of tubes for allowing effluent gas to traverse from an inlet plenum through the internal chamber of the shell to an outlet plenum and a first shroud distributor arranged and configured to direct feed gas flow from the feed gas inlet into the internal chamber proximate the at least one tube sheet, the first shroud distributor having at least one angled cut formed in an end thereof for distributing the flow of feed gas.Ģ. The shroud distributor has at least one angled cut formed in an end thereof for distributing the flow of feed gas.ġ. Additionally, a shroud distributor is arranged and configured to direct feed gas flow from the feed gas inlet to the internal chamber proximate the at least one tube sheet.
The heat exchanger also includes a tube bundle which has a plurality of tubes for allowing effluent gas to traverse from an inlet plenum through the internal chamber of the shell to an outlet plenum. At least one tube sheet is associated with an end of the elongated shell and a plurality of circular baffles are longitudinally spaced apart within the internal chamber of the shell for redirecting feed gas flow within the internal chamber.
The shell has at least one feed gas inlet and feed gas outlet formed in an outer wall for allowing a feed gas to enter and exit the internal chamber. Disclosed is a shell and tube heat exchanger that includes, inter alia, an elongated cylindrical shell that defines a longitudinal axis for the heat exchanger and an internal chamber.
