The vaporized stream is supplied to the mass transfer means as its bottom feed. | 11-05-2015 |

| 20160060190 | PROCESS FOR PRODUCING A SWEETENED HYDROCARBON STREAM - A process of producing a sweetened liquid hydrocarbon stream. In order to prevent the forming of acid species in a sweetening zone, a oxygenate removal zone is disposed upstream of the sweetening zone. The oxygenate removal zone may comprise a water wash or an adsorbent zone, including a regenerable adsorbent. The sweetened stream is formed from a least a portion of liquid natural gas stream which may be scrubbed free of hydrogen sulfide and dehydrated before passing to the oxygenate removal zone. | 03-03-2016 |
| 20160096784 | Separations With Ionic Liquid Solvents - Disclosed are systems and methods which provide a process stream comprising a gaseous component, capture the gaseous component from the process stream by an ionic liquid solvent of a separator, and recover a captured gaseous component from the ionic liquid solvent in a regenerator. A second gaseous component from the process stream may be captured by the ionic liquid solvent of the separator, and the second gaseous component may be recovered from the ionic liquid solvent in the regenerator. Alternatively, the second gaseous component from the process stream may be uncaptured by the ionic liquid solvent, and the uncaptured second gaseous component may be recovered from a membrane unit. | 04-07-2016 |

| 20160122660 | SYSTEM AND METHOD FOR OPTIMIZING DILUENT RECOVERY BY A DILUENT RECOVERY UNIT - A computer-implemented method and a system for optimizing diluent recovery of a diluent recovery unit (DRU) used to recover a diluent from a tailings generated by a bitumen froth treatment process (BFTP). A regression model is determined from data points for operating conditions and corresponding diluent recovery, generated during operation of the DRU. The regression model is used to predict diluent recovery under a particular operating condition and determine a recommended value of the operating condition to achieve a target diluent recovery. The system may graphically display the regression model, the predicted diluent recovery and the recommended value, or cause the DRU to vary the operating conditions towards the recommended value. | 05-05-2016 |
