Publication number: 20210199378Abstract: 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.Type: ApplicationFiled: December 30, 2019Publication date: July 1, 2021Applicant: L'Air Liquide, Societe Anonyme pour l'Etude et l?Exploitation des Procedes Georges ClaudeInventors: Paul KONG, Minh Huy PHAM, May Yee Wendy YIP

Patent number: 10746462Abstract: 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.Type: GrantFiled: April 12, 2018Date of Patent: August 18, 2020Assignee: L'Air Liquide Societe Anonyme Pour L'Etude Et L'Explotation Des Procedes Georges ClaudeInventors: Gilles Poulin, Yves Hardy, Claude Granger, Yoland Plamondon, Minh Huy Pham, May Yee Wendy Yip
