A system for reducing biological and/or chemical contaminants within a feed fluid stream includes in one embodiment at least one recuperator having a cold pass and a hot pass, wherein a contaminated fluid stream is introduced into the cold pass of the recuperator; optionally heating the feed fluid stream using a heater; and introducing the feed fluid stream into a compressor, and compressing the fluid stream to an elevated pressure, resulting in heating of the fluid stream to an elevated temperature, thereby producing a decontaminated fluid stream.

Decontamination systems and methods of use thereof

A method for reducing biological and/or chemical contaminants within a feed fluid stream includes in one embodiment the following steps: a) introducing the fluid stream into a cold pass of at least one recuperator; b) optionally heating the feed fluid stream using a heater; and c) introducing the feed fluid stream into a compressor, and compressing the fluid stream to an elevated pressure, resulting in heating of the fluid stream to an elevated temperature, thereby producing a decontaminated fluid stream.

Decontamination methods of use thereof

A method for providing refrigeration to a refrigeration load which enables the use of environmentally friendly refrigerants with lower power consumption than with conventional refrigerants wherein the low side pressure of the circuit exceeds the critical pressure of the refrigerant fluid and the refrigerant fluid is compressed to a higher supercritical pressure prior to expansion.

Supercritical refrigeration system

A low energy cost process for the co-production of oxygen and nitrogen employing a fuel tube extending into the first oxygen selective ion transport membrane whereby fuel is introduced adjacent to the closed end and flows cocurrently with oxygen containing gas in the annulus and an oxygen selective ion transport membrane having a separator section and a reactor section. An oxygen-containing feedstock, typically air, is compressed and then contacts the cathode side of the separator section where a portion of the oxygen contained within the feedstock is transported to the anode side of the separator section and recovered as an oxygen product gas. Substantially the remainder of the oxygen contained within the feedstock is transported from the cathode side of the reactor section to the anode side and exothermically reacted with a fuel. Following the exothermic reaction, hot nitrogen rich product gas is expanded in a turbine to generate the power necessary to compress the feedstock. Expanded nitrogen rich product gas may then be recovered from the turbine exhaust.

Thermally powered oxygen/nitrogen plant incorporating an oxygen

A cryogenic air separation system employing a double column wherein lower pressure column bottom liquid is pressurized in a single cryogenic liquid pump to provide driving fluid for the main condenser and to provide product elevated pressure oxygen.

Cryogenic air separation system for producing elevated pressure oxygen

A cryogenic rectification system for producing elevated pressure gaseous oxygen wherein pressurized liquid oxygen is vaporized against pressurized working fluid which is then turboexpanded to form a dual phase stream having both vapor and liquid fractions.

Cryogenic rectification system with dual phase turboexpansion

A method and system for supplying compressed air to a process plant using a combustor-turbine unit directly coupled to a bull gear meshing with pinions on which are mounted gas compression stages and expansion stages. Some stages compress a stream of air supplied to the combustor-turbine unit for combustion and to the process plant. Other stages expand or compress other gas streams directed to the combustor-turbine unit or to external applications. Direct energy transfers and intercooling and aftercooling after compression stages enhance the efficiency of the system.

Integration of combustor-turbine units and integral-gear pressure

A radial inflow turbine having a radial nozzle assembly comprising a plurality of vanes, wherein downstream of the throat, the vane suction surfaces, relative to a radius of the circle on which the vane trailing edges lie, have a specified range of angles, or decreasing radii of curvature.

Radial turbine nozzle vane

A turboexpander with improved efficiency wherein fluid is introduced into the rotatable assembly at a negative incidence angle and expanded within the rotatable assembly along a pressure balanced flow path.

High efficiency turboexpander

A centrifugal compressor having a two section diffuser which has a tapered section having a constant diffusing area along its radial length, and a straight section having an increasing diffusing area along its radial length, and a diffusing volute having a throat area significantly larger than conventional designs.
