Steam Heat Exchanger

Steam heat exchanger is an unit of well testing package, which plays an important role to ensure well fluid reaches the necessary temperature level before entering the test separator.
As steam heater transfers the heat from the steam to the well fluid, it can be considered as special type of heat exchangers, mostly used during well testing and well clean-ups. Configuration of the steam heat exchanger depends on the requirements of the oilfield service company or an operator, usually consists of flow-control valves, choke valve, level indicator, pressure and temperature gauges, safety valves and steam pressure controllers.

Working Process

Steam comes from a steam generator and enters the heater. Steam inlet pipeline is equipped with one or two pressure controllers to control steam flow. One or two safety valves are installed in case of pressure increase inside of the vessel. Level indicator shows the level condition inside of the vessel. When steam hits to the pipe, its temperature drops and it becomes liquid, which shall be drained through nozzle below the vessel.
