An apparatus for distillation at cryogenic temperatures can include a cold box module comprising framing and having an upper module section and a lower module section, wherein the upper module comprises a roof; an upper column section disposed within the upper module section; a lower column section disposed within the lower module section; a plurality of support saddles attached to the upper and lower module sections that are configured to provide structural support for the upper and lower column sections when the upper and lower column sections are in a horizontal position during transportation; and means for limiting longitudinal movement of the lower column section when the lower module section is in a horizontal position during transport, wherein the means for limiting longitudinal movement are connected to the lower column section and the lower module section.

Apparatus for distillation at cryogenic temperatures

The jacking system and method for using it to lower an upper column section without the use of a crane is provided. The jacking system is configured to be disposed on a roof of a cold box module and may include: a structural assembly; and a plurality of suspension rods supported at an upper end by the structural assembly, wherein the plurality of suspension rods is configured to provide support to the upper column section.

Apparatus and method for lowering a column section

A method for constructing a cold box module and resulting apparatus is provided. The method can include providing a cold box module having framing and an upper and lower module sections, introducing an upper column section longitudinally into the upper module section while the upper module section is substantially horizontal; introducing a lower column section longitudinally into the lower module section while the lower module section is substantially horizontal; releasably attaching the lower column section to the lower module section using shipping saddle spacers and support saddles; and attaching a skirt attachment to the lower column section and the lower module section, wherein the skirt attachment is configured to limit longitudinal movement of the lower column section when the lower module section is in a horizontal position during transport. After erecting the cold box module at the installation site, the shipping saddle spacers can be removed and the upper column section is lowered using a jacking system located on the roof of the cold box module.

Method for constructing a cold box module

A method for installation of a cryogenic distillation apparatus is provided. The method can include the steps of: providing an upper module section having an upper column section disposed within and secured to the upper module section, wherein the upper module comprises a roof; providing a lower module section having a lower column section disposed within and secured to the lower module section; erecting the lower module section from a horizontal position to a vertical position at an installation site; lifting the upper module section from a horizontal position and attaching the upper module section, while in a vertical position, to a top portion of the lower module section; lowering the upper column section, independent of the upper module section, toward the lower column section; and welding the upper column section and the lower column section together.
