Corrugated steel structure

A method and main heat exchange system for use in a cryogenic air separation plant in which down-flow and thermosiphon heat exchangers are employed to partially vaporize an oxygen-rich liquid produced in a lower pressure column and to condense the nitrogen-rich vapor in a higher pressure column. A greater proportion of the oxygen-rich liquid can be partially vaporized in the down-flow heat exchangers than in the thermosiphon heat exchangers and the nitrogen-rich vapor condensed in the thermosiphon heat exchangers can have a higher oxygen content than the nitrogen-rich vapor condensed in the down-flow heat exchangers. This allows the higher pressure column to operate at a lower pressure than would otherwise be possible. A central conduit can extend from the higher pressure column into the lower pressure column to introduce the nitrogen-rich vapor into at least the down-flow heat exchangers for purposes of reducing pressure drop and column height.

Main heat exchange system and method for reboiling

A cross-corrugated structure packing module is provided for use in mass transfer or heat exchange columns and has particular applicability in severe service applications in which fouling, coking, and erosion are of concern. The structured packing module has a plurality of upright, parallel-extending, corrugated plates. Spacer elements are used to maintain the corrugations of adjacent plates in spaced apart relationship to reduce the opportunity for solids to accumulate on the surfaces of the plates. The plates are also free of apertures or surface treatments that would increase the opportunity for solids to accumulate on the plates.

Structured packing module for mass transfer column and process involving same

A cryogenic air separation system wherein nitrogen vapor from a higher pressure column and oxygen liquid from a lower pressure column each pass down through a once-through main condenser in heat exchange relation and some but not all of the oxygen liquid is vaporized such that the oxygen liquid and vapor exit the condenser in a liquid to vapor mass flowrate ratio within the range of from 0.05 to 0.5 whereby the need for a recirculation pump to ensure avoidance of oxygen boiling to dryness is eliminated.

Cryogenic air separation with once-through main condenser

A system for cooling a power transformer wherein cryogen in liquid or solid form is sprayed into a vaporizer or directly onto a power transformer radiator and the vaporizing and/or sublimating cryogen cools a cooling fluid within the vaporizer or cools the radiator directly to provide cooling to the power transformer.

System for cooling a power transformer

A refrigeration system particularly useful with a multicomponent refrigerant fluid wherein the refrigerant fluid is cooled in an upward leg of a first vertically oriented heat exchanger section and further cooled in a downward leg of a second vertically oriented heat exchanger section prior to refrigeration generation and serial recycle flow through the two heat exchanger sections.

Dual section refrigeration system

A packing section includes a plurality of vertically oriented, diagonally cross-corrugated packing sheets defining a section height. The section height has a base region, a bulk region, and a top region. The base region has a first particular geometry different from the geometry of the bulk region.

Packing for mass transfer column

A packing section includes a plurality of vertically oriented, diagonally cross-corrugated packing sheets defining a section height. The section height has a base region, a bulk region, and a top region. The base region has a first particular geometry different from the geometry of the bulk region. The top region has a second particular geometry different from the geometry of the bulk region, and different from the first particular geometry of the base region.

A system, especially useful under cryogenic conditions, for downflowing cocurrent condensation of vapor against downflowing partially vaporizing liquid, wherein the condensing vapor flows within tubes having fluted internal surfaces and the boiling liquid flows along the outer surfaces of the tubes having re-entrant cavities.

Cryogenic condensation and vaporization system

A corrugated structured packing for forming into modules for use in a rectification column, having both high and low corrugations which reduce the contact points when formed into modules, serving to improve mass transfer effectiveness and thus reduce the requisite column height.

Packing with low contacting crimp pattern

A system particularly useful for the cryogenic rectification of air to produce product, particularly high purity argon, comprising a structured packing arrangement having a defined moderate area density, a defined sharp corrugation angle and at least one of a defined short brick height and a defined packing structure modification.

Structured packing system for reduced distillation column height

A corrugated structured packing for forming into modules for use in a rectification column, having a crimp pattern which is asymmetrical about a line drawn perpendicular to the centerline of the structured packing sheet and whose axial distance along the centerline from trough to adjacent peak is not evenly divided on either side of the centerline, serving to reduce pressure losses that are not efficient in promoting mass transfer and thus reducing the requisite column height.
