Water bath indirect heaters have a long history of successful application in the oil and gas industry. They have been applied to a variety of operations, ranging from the heating of natural gas to the heating of sour crude. The heater consists of three basic elements - the firebox, shell, and flow coil. These elements are carefully designed for each standard size. The firebox is designed to rapidly transfer the heat released by the burning fuel to the water bath. The flow coil is designed to safely contain the process fluid and transfer the required heat from the water bath to the process streams. A variety of coils are available for each firebox size, to allow a selection for the most economical and efficient combination.
Water bath indirect heaters have been used for a wide variety of applications in the oil and gas industry. A few of the more common applications are as follows:
1. Heating natural gas prior to regulation to prevent the formation of frost rings around the buried line downstream of the regulation station. This prevents ground heaving and pavement buckling.
2. Heating high pressure natural gas prior to pressure reduction to prevent the formation of natural gas-water hydrates in the line downstream of the choke or regulator.
3. Heating a natural gas-condensate wellstream prior to separation, with or without an associated pressure reduction, so as to control the separation temperature, prevent the formation of hydrates, and assure good gas-liquid separation.
4 .Heating of crude oil to maintain its temperature above the paraffin pour-point and to reduce its viscosity for easier handling in further lease processing.
5. Heating a natural gas wellstream to maintain it above its hydrate-forming temperature from the well to the processing point even though reduction of wellstream pressure is minimal.
