A modular portable evaporator system for use in a Steam Assisted Gravity Drainage (SAGD) systems having an evaporator, with a sump comprising an oil skimming weir, a short tube vertical heat exchanger including an outer shell containing the short tubes provided for lower water circulation rate. A system further having, external to the evaporator, a compressor 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 demister protecting the compressor from liquid impurities. The evaporator system receives produced water from the process into the sump and provides cleaned hot water to the boiler.
