Publication number: 20230392860Abstract: A facility for the production of liquefied natural gas comprising a liquefaction train. The train comprises a plurality of modules to perform the process steps associated with liquefied natural gas production. The train further comprises a primary cooling loop to cool at least a process stream from each module and a first and a second mixed refrigerants against a first coolant comprising clean water. The primary cooling loop is a closed clean water loop, and the cooling is against an ambient temperature. The train further comprises a first plurality of heat exchangers through which the primary cooling loop extends. The cooling is via heat exchange in at least the first plurality of heat exchangers with respect to the first coolant. More than 50% of the first plurality of heat exchangers are printed circuit heat exchangers, which are adapted to provide at least 80% of the cooling against the ambient temperature.Type: ApplicationFiled: October 12, 2021Publication date: December 7, 2023Inventors: Carolus Antonius Cornelis VAN DE LISDONK, Mark Antonius KEVENAAR, Saheed Olukayode Steven TAIWO

Patent number: 10704829Abstract: A hydrocarbon stream, such as natural gas, is commonly cooled together with a first refrigerant stream, against an evaporating refrigerant in a series of one or more consecutively arranged common heat exchangers. The series comprises of one or more consecutively arranged common heat exchangers comprise a first common heat exchanger, upstream of which first common heat exchanger the hydrocarbon stream and the first refrigerant stream are not commonly cooled. The hydrocarbon stream to be cooled is fed into the first common heat exchanger at a hydrocarbon feeding temperature, while the first refrigerant stream is fed into the first common heat exchanger at a refrigerant feeding temperature. The temperature difference between the hydrocarbon feeding temperature and the refrigerant feeding temperature is lower than 60° C.Type: GrantFiled: January 26, 2016Date of Patent: July 7, 2020Assignee: SHELL OIL COMPANYInventors: Mark Antonius Kevenaar, Johan Jan Barend Pek, Chun Kit Poh

Publication number: 20090095018Abstract: A hydrocarbon stream is liquefied in a method wherein a feed stream is provided, from which feed stream a first stream and a second stream are produced. The first stream is liquefied in a main liquefaction system to provide a first liquefied stream, while the second stream is cooled separately to provide a cooled second stream. The first liquefied stream is combined with the cooled second stream to produce a combined stream, which is separated in a gas/liquid separator into a liquefied hydrocarbon product stream and a gaseous stream. The gaseous stream is warmed to a temperature of above ?40° C. by heat exchanging against any other stream used in the method, wherein the warming of the gaseous stream employs at least heat exchanging against the second stream to provide at least part of the cooling of the second stream.Type: ApplicationFiled: May 9, 2008Publication date: April 16, 2009Inventors: Hillegonda Bakker, Joannes Ignatius Geijsel, Marco Dick Jager, Mark Antonius Kevenaar
