Line Heaters

TSI Fabrication's Line Heater is part of process equipment that supplies heat to oil and gas streams. In gas processing operations, the heater raises the temperature of a gas well stream to minimize or eliminate hydrate formation. In oil production, the heater raises oil temperature to lower viscosity for improved flow, assist in minimizing wax and asphaltene formation and break oil/water emulsion.

There are two types of heaters typically used in this application, indirect fired heater and heat exchanger. Indirect heaters are mostly in use on land. In an indirect fired heater, a firing tube provides the heating source to a liquid bath such as water. The water bath is at ambient pressure. The liquid temperature rises and heats piping coils in which the well stream flows under pressure up to 15,000 psi. On the other hand to completely eliminate flame source near an offshore well, a heat exchanger is used to heat well stream. The heat exchanger uses steam to raise temperature of piping coils. Steam chamber can be pressured up to 350 psi. Steam is typically provided by a boiler or a utility steam on location.

TSI Fabrication offers various size and heat duty heaters. For your heater needs, either indirect fired or heat exchangers contact your TSI Fabrication representative.
