ABSTRACT:
The treating apparatus and method of the present invention improve the efficiency and reliability of flash treating crude oil by including a recycled oil pumping loop that takes crude oil from a flashing section of a vessel and feeds it to either the inlet of a treater section or through a heater into a connecting pipe between the treater section and the flashing section, thereby eliminating the need of a fired heater in the flashing section.
