20090165873 | Variable ratio flow splitter for a flowstream - A splitter for a pressurized primary flowstream of a mobile phase is provided. The splitter comprises a first splitting stage that divides the primary flowstream between a major split flowstream and a minor split flowstream by means of a first and a second restrictive flow element; a first dilution stage that combines a dilution flow source with the minor split flowstream to create a diluted minor flowstream;a second splitting stage that divides the diluted minor flowstream between a secondary major diluted flowstream and a secondary minor diluted flowstream by means of a third restrictive element in the secondary minor diluted flow stream; and a second dilution stage wherein a conditioning flow source conditions the secondary minor diluted flow stream after the third restrictive element prior to outlet of the secondary minor diluted flowstream from the splitter. | 07-02-2009 |
20100252229 | GEOTHERMAL ENERGY SYSTEM - A geothermal energy system with reverse thermodynamic flow scheme that employs a pump or a compressor in series with a ground heat rejection or a ground heat absorber. The pumped geothermal energy system evaporates and condenses the working fluid at substantially the same pressure in the ground loop. The working fluid could be carbon dioxide, Freon, water or any other suitable refrigerant. The compressive geothermal system condenses the working from a vapor to a liquid above, below, and substantially equal to critical pressure using carbon dioxide as the working fluid. | 10-07-2010 |
20100267976 | CONTINUOUS PROCESSING AND SOLIDS HANDLING IN NEAR-CRITICAL AND SUPERCRITICAL FLUIDS - Apparatus for the continuous processing and solids handling in first near-critical and supercritical fluids. The present invention also allows for treatment of the starting material with the first near-critical or supercritical fluid. The remaining raffinate is then continuously transferred and may be collected in a second fluid. | 10-21-2010 |
20110180481 | High Pressure Flash Chromatography - A method for separating a sample using high pressure flash chromatography is provided. The method comprises the steps of: i) providing a pressurized vessel containing an adsorption material; ii) pressurizing a compressible fluid, optionally containing a cosolvent, to create a mobile phase; iii) premixing the sample with the mobile phase or optionally placing the sample in the pressurized vessel; iv) eluting the mobile phase through the pressurized vessel, to obtain a separated sample; v) heating the mobile phase containing the separated sample after the mobile phase exits the pressurized vessel to remove the compressible fluid; and iv) collecting the separated sample. The pressurized vessel contains an adsorption material having a particle size of 10-100 microns, and the pressure of the adsorption vessel is held at 50-350 bar during elution. Also provided is an apparatus for carrying out the above method. | 07-28-2011 |
20130074733 | METHOD OF CLEANING A MATERIAL - Solid waste of metallic or plastic composition is cleansed of contaminants by solvent extraction using a combination of primary solvent and co-solvents that may be pressurized and heated to above the critical state. The process is particularly applicable to the remediation of solids contaminated with polychlorinated biphenyls. Contamination can be reduced to less than two parts per million (by weight). | 03-28-2013 |
20160003552 | COUNTERCURRENT HEAT EXCHANGER/REACTOR - Counter-flow heat exchanger is constructed with plenums at either end that separate the opposing fluids, the channels of which are arrayed in a checkerboard patterns, such that any given channel is surrounded by channels of opposing streams on four sides—laterally on both sides and vertically above and below. | 01-07-2016 |
20160025392 | MULTICYCLE SYSTEM FOR SIMULTANEOUS HEATING AND COOLING - System that delivers heating and/or cooling to multiple zones using two or more thermodynamic cycles that are tailored specifically to the overall load and in so doing provide a heating or cooling effect at high efficiency using only a single work fluid and a single accumulator connected to two or more external media. | 01-28-2016 |
