Patent number: 12044468Abstract: A method of cooling a boil-off gas (BOG) stream from a liquefied gas tank comprising at least the step of heat exchanging the BOG stream with a first refrigerant in a heat exchanger, the heat exchanger having an entry port and a warmer exit port, and comprising at least the steps of: (a) passing the first refrigerant into the entry port of the heat exchanger and into a first zone of the heat exchanger to exchange heat with the BOG stream, to provide a first warmer refrigerant stream; (b) withdrawing the first warmer refrigerant stream from the heat exchanger at an intermediate exit port between the entry port and the warmer exit port; (c) passing the first warmer refrigerant stream through an entry port located in a second zone of the heat exchanger that is warmer than the first zone (d) passing an oil-containing refrigerant stream through an entry port located in a second zone of the heat exchanger that is warmer than the first zone; (e) mixing the first warmer refrigerant stream and the oil-containing streaType: GrantFiled: August 21, 2020Date of Patent: July 23, 2024Assignee: LGE IP Management Company LimitedInventor: Nikola Felbab

Patent number: 12013179Abstract: A method of cooling a boil off gas stream from a liquefied cargo (50a) in a floating transportation vessel is described. The method comprises: compressing a boil off gas stream in two or more stages of compression to provide a compressed BOG discharge stream; cooling the compressed BOG discharge stream against one or more first coolant streams to provide a first cooled compressed BOG stream; cooling the first cooled compressed BOG stream against at least one second coolant stream to provide a second cooled compressed BOG stream; providing a vessel fuel stream from the liquefied cargo; using the vessel fuel stream as a coolant stream to cool either the compressed BOG discharge stream, or the first cooled compressed BOG stream, or both said streams.Type: GrantFiled: March 25, 2020Date of Patent: June 18, 2024Assignee: LGE IP Management Company LimitedInventor: Martin Halcrow

Publication number: 20240019208Abstract: A method and apparatus for recovering carbon dioxide (CO2) from an oxyfuel combustion engine exhaust stream is described. The method comprises: providing and separating an oxyfuel combustion engine exhaust stream to provide a first liquefied CO2 stream and a first waste gas stream; condensing at least a portion of the first waste gas stream to provide a partly condensed waste gas stream; and separating the condensed waste gas stream to provide a second waste gas stream, and a second liquefied CO2 stream.Type: ApplicationFiled: December 1, 2021Publication date: January 18, 2024Applicant: LGE IP MANAGEMENT COMPANY LIMITEDInventor: Nikola FELBAB

Patent number: 11561042Abstract: The present invention is a modification of a typical single mixed refrigerant (SMR) cycle for LNG re-liquefaction in particular, that allows the use of a cost-efficient oil-injected screw compressor in the mixed refrigerant system. In comparison with the typical arrangement, the present innovation allows for reduced complexity, fewer pieces of equipment, and reduced capital cost.Type: GrantFiled: February 27, 2017Date of Patent: January 24, 2023Assignee: LGE IP Management Company LimitedInventor: Nikola Felbab

Patent number: 10724508Abstract: A linear compressor is provided. The linear compressor may include a shell having a cylindrical shape, a shell cover that covers both open ends of the shell, a cylinder accommodated into the shell and defining a compression space for a refrigerant, a piston that reciprocates within the cylinder in an axial direction to compress the refrigerant within the compression space, a motor assembly including a motor that provides power to the piston and a stator cover that supports the motor, and resonant springs seated on the stator cover that support the piston to allow the piston to perform a resonant motion. The resonant springs may be circularly arranged at three points having a same interval around a center in an axial direction.Type: GrantFiled: April 19, 2017Date of Patent: July 28, 2020Assignee: LGE ELECTRONICS INC.Inventors: Junghae Kim, Hyunsoo Kim, Jeonguk Byun, Jongwoo Lee, Eonpyo Hong
