Line Heaters

Line Heaters allow the process stream to maintain an ideal temperature as pressures are rapidly reduced to sales line requirements, increasing overall performance in equipment downstream. They offset the effect of sudden temperature drops that happen when the well stream passes through the pressure-reducing choke. This equipment can also be used to heat gas transmission lines and heating crude oil.

 

The Line Heater consists of three components: shell, firetube and coil. The process stream flows through the coil, which is immersed in the upper portion of the liquid media bath of the shell. The coil preheats the flow stream before reducing the pressure across a restricting choke followed by post-heating coils. Fuel gas is burned in the firetube and indirectly transfers heat to the media, then to the coil, and finally to the process stream.
