Publication number: 20190143261Abstract: A method for reducing the loss of solvent during carbon dioxide capture from flue gas in an amine based solvent process by the steps of feeding a flue gas containing carbon dioxide to an absorber column containing an amine solvent; absorbing carbon dioxide in the amine solvent forming a rich solvent; feeding the rich solvent to at least one inter-stage cooler; recovering the rich solvent and feeding the rich solvent to a regeneration column; separating the carbon dioxide from the rich solvent and recovering the carbon dioxide to form a lean solvent; feeding the lean solvent to the absorber column. The improvement is realized by one of feeding steam to the flue gas; feeding steam to the absorber column after introduction of amine solvent; feeding the flue gas stream to a demister before feeding to the absorber column or increasing the lean solvent inlet temperature into the absorber column.Type: ApplicationFiled: January 15, 2019Publication date: May 16, 2019Inventors: Rachid Mabrouk, Stevan Jovanovic, Joseph Naumovitz, Ramachandran Krishnamurthy

Publication number: 20170038131Abstract: In a liquid air energy system, cold storage is accomplished using heat pipes as the heat transfer device. The cold energy storage unit is charged by feeding high pressure air to a liquid cold storage unit wherein the high pressure air becomes liquid air; feeding the liquid air to a liquid air storage unit; feeding cold liquid to the liquid cold storage unit wherein the cold liquid becomes warm liquid; and feeding warm liquid to a warm liquid storage unit.Type: ApplicationFiled: August 5, 2015Publication date: February 9, 2017Inventors: Joseph Naumovitz, Martin Kibili

Publication number: 20150306541Abstract: A method is provided for separating hydrogen sulfide and carbon dioxide from an offgas stream from a direct reduced iron furnace. The offgas is directed to a separation device which will separate the carbon dioxide and hydrogen sulfide using a hydrogen sulfide absorber and a carbon dioxide absorber. The hydrogen sulfide can be recycled for reuse in the furnace and the carbon dioxide recovered for other additional uses.Type: ApplicationFiled: March 19, 2015Publication date: October 29, 2015Inventors: Joseph Naumovitz, Stevan Jovanovic, Wei Wei

Publication number: 20150240995Abstract: A modular pump is in fluid communication with a vaporizer which is in fluid communication with a coolant exchanger. A fluid such as a cryogenic liquid like liquid nitrogen or liquid carbon dioxide is pumped via a high pressure modular pump to the vaporizer where the liquid becomes gas. The higher pressure gas is cooled by a coolant exchanger and can be fed to an onsite unit operation such as an enhanced oil recovery operation. The modular pump is unique to one fluid and may be removed and replaced by a modular pump that is unique to a different fluid. The coolant exchanger is in a thermal exchange relationship with a combustion engine which powers a hydraulic pump which feed hydraulic fluid to drive the high pressure pump.Type: ApplicationFiled: May 11, 2015Publication date: August 27, 2015Inventor: Joseph Naumovitz
