Abstract: An improved rod baffle heat exchanger and method for manufacturing the same are disclosed in which the tube bundle thereof comprises a plurality of tubes supported intermediate their ends by at least one outer ring and a plurality of baffle rods carried by the outer ring and extending between parallel tube rows. The baffle rods comprise circular standard rods and circular substitute rods wherein the diameter of the substitute rods differs from that of the standard rods. The use of different sized circular rods allows firm contact to be achieved between the rods and tubes of the tube bundle in order to avoid tube vibration while also avoiding the problems of rod-to-tube tolerance buildup.

Abstract: A method of extracting bitumen from a subsurface tar sand bed wherein a shell of frozen earth is formed around the periphery of at least a portion of the tar sand bed, followed by recovering bitumen from such portion of the tar sand bed within the shell of frozen earth by suitable means such as, for example, solvent extraction. Also disclosed is apparatus for freezing the earth surrounding one of a plurality of boreholes drilled in the earth within earth freezing distance of each other around the periphery of such portion of the tar sand bed. The apparatus comprises concentric outer and inner conduits with the outer conduit having two strips of thermal insulation extending along substantially the full length of the exterior surface of the outer conduit, separated by two strips, preferably longitudinally finned, of relatively high thermal conductivity extending along substantially the full length of the exterior surface of the outer conduit so as to provide a predetermined freezing pattern about the axis of a borehole when refrigerant is circulated through the apparatus.

Abstract: An improved rod baffle heat exchanger and method for manufacturing the same are disclosed in which cross-support members are used to prevent support rod movement and to provide increased rigidity in the heat exchanger. The cross-support members have a threaded circular section at each end, to which threaded nuts are attached. The threaded nuts rest on a protective pad, which is adjacent to the outermost tubes. As the nuts are tightened at each end of the threaded cross-support member, the baffle support rods are brought into firm contact with adjacent tubes.

Abstract: A method for fabricating a support apparatus for tubes in a U-bend portion of a tube bundle. The support apparatus includes a U-tube ring positioned around the tubes in the U-bend portion and having first and second tube separation elements extending therefrom through first and second lanes between the tubes, respectively. The first tube separation elements are preferably characterized by flat plates or strips defining a plurality of holes therethrough, and the second tube separation elements are preferably characterized by rods or bars extending through aligned sets of holes in the plates or strips. A support bar extends between opposite end portions of the ring, and the plates have notches therein for engaging corresponding notches in the support bar and ring. The ring and support bar are slidably attachable to a mounting bracket on a tube support used to support a first and second pass of longitudinal tubes in the tube bundle.
