Sander Kaart patentsRecent bibliographic sampling of Sander Kaart patents listed/published in the public domain by the USPTO (USPTO Patent Application #,Title):
11/17/11 - 20110277498 - Method and apparatus for controlling a regrigerant compressor, and use thereof in a method of cooling a hydrocarbon stream
A method of controlling one or more refrigerant compressors (12) for one or more gaseous streams (10) at a normal operating temperature. At least one refrigerant compressor (12) has a vapour recirculation line (30). A compressor feed stream (10a) is provided from a combination of a vapour recirculation stream (30)...
Inventors: Sander Kaart
10/06/11 - 20110239701 - Method of rejecting nitrogen from a hydrocarbon stream to provide a fuel gas stream and an apparatus therefor
Method of, and apparatus for, rejecting nitrogen from a hydrocarbon stream to provide a fuel gas stream. A hydrocarbon stream is at least partially liquefied and subsequently expanded. The expanded hydrocarbon stream is fractionated in a fractionation column to provide an nitrogen-rich hydrocarbon stream and a nitrogen-lean hydrocarbon stream. The...
Inventors: Sander Kaart, Marco Dick Jager
05/13/10 - 20100115993 - Process for removing mercaptans from liquefied natural gas
The invention provides a process for producing purified natural gas, the process comprising the steps of: expanding a pressurised natural gas stream comprising at least 4 ppmv of mercaptans and supplying it to a first separation column, in which the natural gas stream is separated into a gaseous overhead stream...
Inventors: Anthonius Maria Demmers, Sander Kaart, Adriaan Johannes Kodde
03/25/10 - 20100071409 - Method and apparatus for liquefying a hydrocarbon stream
A method and apparatus for liquefying a hydrocarbon stream (10) such as natural gas. The method comprises the steps of: (a) compressing the hydrocarbon stream (10) using one or more compressors (12) driven by one or more steam turbines (14) to provide a compressed hydrocarbon stream (20); (b) heat exchanging...
Inventors: Sander Kaart
02/04/10 - 20100024474 - Method and apparatus for cooling a hydrocarbon stream
Method of cooling a hydrocarbon stream (10) such as natural gas, the method at least comprising the steps of (a) heat exchanging the hydrocarbon stream (10) against a first refrigerant stream (20) to provide a cooled hydrocarbon stream (30) and an at least partly evaporated refrigerant stream (40); (b) compressing...
Inventors: Sander Kaart, Mark Antonius Kevenaar
11/19/09 - 20090282862 - Method and apparatus for producing a cooled hydrocarbon stream
A method and apparatus for cooling two or more liquefied hydrocarbon streams. First (30) and second (30a) liquefied hydrocarbon streams are provided and combined thereby providing a combined liquefied hydrocarbon stream (40). The combined liquefied hydrocarbon stream (40) is further cooled against a refrigerant thereby providing a further cooled liquefied...
Inventors: Francois Chantant, Jolinde Machteld Van De Graaf, Marco Dick Jager, Sander Kaart, Robert Klein Nagelvoort
10/01/09 - 20090241593 - Method and apparatus for cooling a hydrocarbon stream
A method of liquefying natural gas from a feed stream (10) comprising at least the steps of: passing the feed stream (10) against a mixed refrigerant being cycled through a heat exchanger (12), to provide an at least partly liquefied hydrocarbon stream (20) having a temperature below −100° C.; outflowing...
Inventors: Marco Dick Jager, Sander Kaart
07/30/09 - 20090188277 - Method and apparatus for controlling a refrigerant compressor, and method for cooling a hydrocarbon stream
A refrigerant stream is passed through at least one heat exchanger to provide a first at least partially evaporated stream and a second at least partially evaporated stream. A first compressor feed stream is provided from the first partially evaporated stream, and a second compressor feed stream is provided from...

The bibliographic references displayed about Sander Kaart's patents are for a recent sample of Sander Kaart's publicly published patent applications. The inventor/author may have additional bibliographic citations listed at the USPTO.gov. FreshPatents.com is not associated or affiliated in any way with the author/inventor or the United States Patent/Trademark Office but is providing this non-comprehensive sample listing for educational and research purposes using public bibliographic data published and disseminated from the United States Patent/Trademark Office public datafeed. This information is also available for free on the USPTO.gov website. If Sander Kaart filed recent patent applications under another name, spelling or location then those applications could be listed on an alternate page. If no bibliographic references are listed here, it is possible there are no recent filings or there is a technical issue with the listing--in that case, we recommend doing a search on the USPTO.gov website.
