Abstract

A reboiler for dehydrating glycol used in a gas dehydration system having improved thermal efficiency including a horizontal boiler vessel, a horizontal heater within the boiler vessel having a fuel burner therein, a heat exchange vessel extending downwardly from the boiler vessel including piping to receive heated glycol therein from the interior of the boiler vessel and a heat exchange conduit within the heat exchange vessel extending exteriorly of it, one end of the heat exchange conduit communicating with the interior of the boiler vessel to transfer wet glycol into the boiler vessel and a glycol inlet at one end of the conduit extending externally of the vessel and the heat exchange vessel having a dehydrated glycol outlet, hot dehydrated glycol from the boiler vessel passing downwardly through the heat exchange vessel to thoroughly exchange heat with the incoming wet glycol to thereby conserve heat applied to the glycol for dehydration.
