An air compression system and method for an air separation plant in which air is compressed in a series of compression stages and a temperature swing adsorption unit adsorbs water vapor and carbon dioxide. The temperature swing adsorption unit is situated at a location of the compression stages such that air pressure upon entry into the adsorbent beds is between about 400 psia and about 600 psia. Each of the adsorbent beds of the unit have a minimum transverse cross-sectional flow area that will set the air velocity of the air to a level below that at which adsorbent bed fluidization would occur. Such operation allows fabrication costs of the adsorbent beds to be reduced because less adsorbent and smaller adsorbent beds are required while power consumption will be at a minimum.

Air compression system and method

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.

Energy delivery system for a gas transport vessel containing low vapor pressure gas

Systems, apparatuses and methods for vapor phase fluid delivery to a desired end use are provided, wherein the conditions of the system are monitored to determine when the water concentration or supply vessel surface temperature exceeds a specified value or when the low vapor pressure fluid pressure falls below a specified value for the purpose of removing a first supply vessel from service by discontinuing vapor flow from the first supply vessel and initiating vapor flow from a second supply vessel.

Low vapor pressure high purity gas delivery system

This invention relates to methods and systems for detecting contaminants that can precipitate and deposit on a workpiece during a carbon dioxide application, especially contaminants that are already present and dissolved in the fresh carbon dioxide fed to the application. One aspect of this invention includes a method of detecting contaminants dissolved in a carbon dioxide stream, including the steps of sampling at least a portion of the carbon dioxide stream to form a carbon dioxide sample; modifying at least one physical condition of the carbon dioxide sample to form an aerosol that includes gaseous carbon dioxide and at least one suspended contaminant; and detecting the number of particles of suspended contaminant in at least a portion of the carbon dioxide sample with at least one particle counter. A system for continuously detecting contaminants dissolved in a carbon dioxide stream is also described.

Method for analyzing impurities in carbon dioxide

Carbon dioxide is purified through the use of catalytic oxidation. Carbon dioxide is exposed to at least one catalyst, oxidizing at least a portion of the nonvolatile organic residues to form purified carbon dioxide that is directed to an application. Carbon dioxide that is in a near-critical, critical, or supercritical phase can be exposed to the catalyst.
