Abstract
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.
