A system for delivering vapor phase fluid at an elevated pressure from a transport vessel containing liquefied or two-phase fluid is provided. The system includes: (a) a transport vessel positioned in a substantially horizontal position; (b) one or more energy delivery elements disposed on the lower portion of the transport vessel wherein the energy delivery devices include a heating means and a first insulation means, wherein the energy delivery devices are configured to the contour of the transport vessel; (c) one or more substantially rigid support devices disposed on the outer periphery of the energy delivery devices, wherein the support devices hold the energy delivery devices in thermal contact with a lower portion of the transport vessel; and (d) one or more attaching devices secure the rigid support devices onto the transport vessel and hold the energy delivery devices between the substantially rigid support device and a wall of the transport vessel.

Method and apparatus of separating a nitrogen from a compressed and purified feed stream in a cryogenic rectification plant that employs a distillation column to produce a nitrogen-rich vapor as a column overhead and an oxygen-rich liquid column bottoms. Reflux is generated for the column by condensing part of the nitrogen-rich vapor within a down-flow heat exchanger. A stream of the oxygen-rich liquid column bottoms is introduced into an ejector which draws a stream of an oxygen-rich liquid phase produced from the outlet of a down-flow heat exchanger. The combined oxygen-rich liquid exiting the ejector is fed to the down-flow heat exchanger to condense the nitrogen-rich vapor. In such manner, part of the oxygen-rich liquid phase is recirculated to prevent dry-out of the down-flow heat exchanger outlet and to maintain effective condensation of the nitrogen-rich vapor.

A method for providing refrigeration wherein a first multicomponent refrigerant is condensed to form a saturated liquid and vaporized against a condensing second multicomponent refrigerant which has a dew point less than the dew point and preferably the bubble point of the saturated liquid, and has a bubble point greater than that of the vaporizing first multicomponent refrigerant, and after providing refrigeration to a refrigeration load, may be superheated against the condensing first and second multicomponent refrigerants.
