| 20110167869 | PROCESS AND APPARATUS FOR REMOVING GASEOUS CONTAMINANTS FROM GAS STREAM COMPRISING GASEOUS CONTAMINANTS - A transformer has a toroidal core with an opening therein and a plurality of wires to define a central winding section, a plurality of outer twisted wire sections and a plurality of wire proximity sections positioned between each outer twisted wire section and the central winding section. The central winding section includes a plurality of wires wrapped around the toroidal core and coupling a conductor of a primary side of a transformer and a conductor of a secondary side of a transformer. Each outer twisted wire section includes at least a pair of wires twisted together in a predetermined twisted pattern that are electrically connected to but spaced from the central winding section. The wire proximity section is configured to maintain physical proximity between the conductor of the primary side of the transformer and the conductor of the secondary side of the transformer. | 07-14-2011 |
| 20120186296 | PROCESS AND APPARATUS FOR SWEETENING AND LIQUEFYING A GAS STREAM - A process and apparatus for liquefying a gas stream comprising hydrocarbons and sour species is provided in which the sour species are removed in liquefied form as the sweetened gas stream is progressively cooled to liquefaction temperatures. The process involves cooling the gas stream in a manner to produce a cooled gas stream comprising gaseous hydrocarbons and residual sour species. The cooled gas stream is then treated with a cold solvent to deplete the cooled gas stream of residual sour species. The resulting cooled sweetened gas stream is then further cooled to produce liquid hydrocarbons. | 07-26-2012 |
| 20130000350 | APPARATUS AND METHOD FOR RECOVERY OF HYDROCARBONS FROM THE SURFACE OF A BODY OF WATER - An apparatus for the removal of hydrocarbons from a body of water comprising a temperature reduction device comprising a heat exchange in thermal communication with a flow of a liquefied cryogen, the temperature reduction device being adapted to receive a hydrocarbon/water mixture, position a first surface of the at least partially phase separated mixture in thermal communication with the heat exchanger, and reduce the temperature of the at least partially phase separated mixture to a temperature sufficient to cause the hydrocarbon phase to at least partially congeal or at least partially solidify. | 01-03-2013 |
| 20150300735 | Method and System For Starting Up A Distillation Tower - The present disclosure provides method for clean methane startup of a distillation tower. The method includes maintaining a rectifier section and a lower section in the distillation tower, feeding stream to the lower section, directly feeding methane to at least one of the rectifier section and a rectifier section outlet line of the rectifier section when a contaminant concentration of the contaminant exiting as a vapor in an upper portion of the lower section is outside of a predetermined concentration and introducing the vapor from the lower section to the rectifier section when the contaminant concentration exiting the upper portion of the lower section is within the predetermined concentration. | 10-22-2015 |
| 20150362251 | Method For Separating A Feed Gas In A Column - A system and methods for processing a feed gas in a column are provided herein. A method includes feeding a feed gas into a port of a sleeve disposed around at least a portion of a periphery of the column. The sleeve includes a space between an outer wall of the column and an inner wall of the column. The sleeve releases the feed gas into the column through an opening disposed at an opposite end of the sleeve from the port. | 12-17-2015 |

| 20110107791 | OIL VAPOR CLEANER - An apparatus for recovery of solids from a vapor, the apparatus including: a vessel comprising a cylindrical portion on top of an angled portion; a vapor inlet located in the cylindrical portion for introducing a solid-vapor mixture tangentially to the cylindrical portion; at least one inlet nozzle disposed in a top of the vessel for spraying a hydrocarbon fluid into the vessel; an indirect heat exchange device disposed concentrically within the cylindrical portion, thereby providing an annulus for vapor and hydrocarbon flow; a heat exchange device disposed at an exterior of the angled portion; an outlet located at a bottom of the angled portion to recover the vapor having a reduced solids content and a solid-hydrocarbon mixture. Also disclosed are processes to clean an oil vapor using such an apparatus. | 05-12-2011 |
