la Compact evaporator for modular portable SAGD process By www.freepatentsonline.com Published On :: Tue, 10 Feb 2015 08:00:00 EST A modular portable evaporator system for use in a Steam Assisted Gravity Drainage (SAGD) systems having an evaporator, with a sump including an oil skimming weir, a short tube vertical falling film heat exchanger including an outer shell containing short tubes provided for lower water circulation rate. The system further having external to the evaporator, a compressor for compressing evaporated steam from the tube side of the heat exchanger and routing to the shell side of the same exchanger, a distillate tank to collect hot distilled water, a recirculation pump to introduce liquids from the sump into the heat exchanger and an external suction drum protecting the compressor from liquid impurities. The evaporator system receives produced water from the SAGD process into the sump and provides cleaned hot water to a boiler. Full Article

la Process and system for heating or cooling streams for a divided distillation column By www.freepatentsonline.com Published On :: Tue, 07 Apr 2015 08:00:00 EDT One exemplary embodiment can be a system for separating a plurality of naphtha components. The system can include a column, an overhead condenser, and a side condenser. Generally, the column includes a dividing imperforate wall with one surface facing a feed and another surface facing at least one side stream. Typically, the wall extends a significant portion of the column height to divide the portion into at least two substantially vertical, parallel contacting sections. Typically, the overhead condenser receives an overhead stream including a light naphtha from the column. Usually, a side condenser receives a process stream from the column and returns the stream to the column to facilitate separation. A cooling stream may pass through the overhead condenser and then the side condenser. Full Article
la Evaporative desalination device of multi stage and multi effect using solar heat By www.freepatentsonline.com Published On :: Tue, 12 May 2015 08:00:00 EDT An evaporative desalination device includes a multi stage vapor generator that generates vapor by passing a hot water supply pipe successively through a plurality of vapor generators to evaporate sea water inside thereof, a multi effect vapor generator that uses vapor in the respective vapor generators as heat source and forms a plurality of evaporator groups which can adjust a number of evaporators disposed inside the respective evaporator groups and produce fresh water according to amounts of supplied vapor to evaporate sea water in the evaporator groups on an outer circumference surface of an evaporation tube by heat of vapor flowing in the evaporation tube, and a discharge unit that condenses vapor in the multi effect generator by sea water to discharge fresh water in liquid state, and returns and supplies portions of discharged sea water to the multi stage vapor generator and the multi effect evaporator.
