1. A process for heating a hydrocarbon feed stream for a reactor, the process comprising:
heating a hydrocarbon feed stream for a reactor in a heat exchanger to provide a pre-heated hydrocarbon feed stream, wherein the pre-heated hydrocarbon feed stream from the heat exchanger is a vapor stream;
heating the pre-heated hydrocarbon feed stream in a charge heater to form a heated hydrocarbon feed stream;
passing the heated hydrocarbon feed stream from the charge heater to the heat exchanger to heat the hydrocarbon feed stream and provide the pre-heated hydrocarbon feed stream and a heat depleted hydrocarbon feed stream; and,
passing the heat depleted hydrocarbon feed stream to the reactor,
wherein the reactor comprises a vapor phase hydrotreating reactor.
