  • Publication number: 20210199378
    Abstract: A method and apparatus for reducing heat bumps following regeneration of adsorbers in an air separation unit is provided. Certain embodiments of the current invention utilize the two waste streams available at very different temperatures from the two main exchangers (low-pressure and high-pressure core exchangers) for regeneration of the front-end purification adsorbers in the air separation unit (ASU) to reduce its energy consumption without compromising the stability of process. Certain embodiments help to eliminate/minimize high air temperature disturbance (heat bump) for the process downstream of the front-end purification unit during the transition from offline to online.

  • Patent number: 10746462
    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.

  • Patent number: 10739068
    Abstract: 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.
