HEATER-TREATER

摘要

In a heater-treater, a tank is divided into separate heating and treating sections, and the heating section is in turn divided into a receiving zone and an enclosed heating chamber. A pair of downcomers convey emulsion from the top of the receiving zone to the bottom of the heating chamber, and a portion of the emulsion flowing from the downcomers is directed across a discharge passageway to flush sediment and free water from the chamber. The emulsion flows diagonally upwardly in the heating chamber past a pair of firetubes and is conveyed from the top of the chamber to the bottom of the treating section by a conduit. The operation of the firetubes is controlled by thermostats located in the upper portion of the heating chamber adjacent the inlet of the conduit.
