Abstract: A gas oil separation plant (GOSP) and method for receiving crude oil from a wellhead and removing gas, water, and salt from the crude oil, and discharging export crude oil. The GOSP includes online analyzer instruments for performing online analysis of salt concentration in multiple streams in the GOSP. Based in part on the online analysis, the salt content in the export crude oil may be determined and the flowrate for wash water supplied to the desalter vessel may be specified.

Abstract: A method of demulsifying an emulsion is provided, the method comprising an initial step of supplying the emulsion to a fluid processor passage (14) having an inlet (16) and an outlet (18), wherein the cross sectional area of the passage (14) between the inlet (16) and outlet (18) does not reduce below the cross sectional area at the inlet (16). A transport fluid is supplied from a transport fluid source (60) to a transport fluid nozzle (34) which circumscribes the passage (14) and opens into the passage (14) intermediate the inlet (16) and the outlet (18). The transport fluid is accelerated through a throat (38) of the transport fluid nozzle (34), the throat (34) having a cross sectional area which is less than that of either the nozzle inlet (36) or nozzle outlet (40).

Abstract: Process for separating an emulsion of a bituminous oil and water into a liquid water phase and a liquid bituminous oil phase, wherein the following steps are performed: (a) raising the temperature of the bituminous oil/water emulsion having a temperature of below 100 ° C. to a temperature of above 140 ° C., and (b) performing a phase separation wherein a water phase and oil phase is obtained, wherein the heating of the emulsion in step (a) is effected by first mixing part of oil phase obtained in step (b) having a temperature of above 140 ° C. with the bituminous oil/water emulsion and subsequently raising the temperature of the resulting mixture to a temperature of above 140 ° C. by making use of indirect heat exchange means.
