Miller, C L

A waste heat recovery system for a heater treater which elevates the overall energy imparted into crude oil from a finite amount of combustion gases is described. The system includes a vertical heat exchanger supported from the shell of the heater treater. The exchanger has an outer housing within which a plurality of longitudinally arranged tubes are disposed. Untreated crude flows through the interior of the tubes while waste heat from the fire tube is conducted into the lower end portion of the housing so that the outer surface of the tubes contact and extract heat from the flue gases. The flue gases exit through the upper end of the housing. The temperature elevation of the incoming crude is controlled by a damper assembly located at the lower extremity of the exchanger, which admits atmospheric air into the housing. The incoming untreated crude oil is elevated in temperature, which increases the efficiency of the unit by lowering the gas consumption and increasing the throughput and enables the treated crude oil to leave the heater treater at an elevated temperature.
