Patent number: 11021675Abstract: An improved process for producing refined oils free of contaminating waxes, resins, and lipids from botanical plant matter using an improved in-line winterization process is disclosed. The biomass is fed into an extraction vessel where the oils are extracted using a solvent, followed by a two-stage separation. Both the temperature and pressure of the solvent going into the separators are controlled for effective separation. Additional solvent is added to enhance the separation efficiency between the refined oil and the undesired fraction containing the contaminants. This process provides an alternative to current wax mitigation techniques, such as alcohol based solvent winterization.Type: GrantFiled: September 13, 2019Date of Patent: June 1, 2021Assignee: Thar Process, Inc.Inventors: Lalit Chordia, Sasikumar Ramesh

Patent number: 8468845Abstract: 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.Type: GrantFiled: April 1, 2010Date of Patent: June 25, 2013Assignee: Thar Geothermal, Inc.Inventors: Lalit Chordia, John C. Davis

Patent number: 8460550Abstract: 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.Type: GrantFiled: May 25, 2010Date of Patent: June 11, 2013Assignee: Thar Process, Inc.Inventors: Lalit Chordia, Jose Martinez, Andrew Kegler, Desai Bhishmakumar

Publication number: 20130074733Abstract: 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).Type: ApplicationFiled: June 9, 2011Publication date: March 28, 2013Inventors: Lalit Chordia, Jose L. Martinez, Bhishmakumar Desai

Patent number: 8246834Abstract: 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.Type: GrantFiled: January 26, 2011Date of Patent: August 21, 2012Assignee: Waters Technologies CorporationInventors: Lalit Chordia, Harbaksh Sidhu, Todd Palcic, John Whelan
