This disclosure provides methods for decoking tubular passes of crude oil heaters and processed hydrocarbon heaters. The method permits continued operation of an associated crude oil processing unit or a processed hydrocarbon processing unit receiving crude oil or processed hydrocarbons from the heater during the decoking operation. The decoking operation utilizes dry steam to remove coke from passes within the crude oil heater or processed hydrocarbon heater and dry steam to maintain balanced operation of the crude oil processing unit or processed hydrocarbon processing unit.
