Abstract
Processes and apparatuses for heating a feed stream for a reactor which has a charge heater. At least one process stream provides heat so that a pre-heated feed stream passed to the charge heater is a vapor stream. The process stream may be the heated stream from the outlet of the charge heater. Alternatively, the process stream may be the effluent stream from the reactor that has been heated.
Claims6
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 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 to the reactor;
- recovering a hydrocarbon effluent stream from the reactor;
- heating the hydrocarbon effluent stream in a heating zone to provide a heated hydrocarbon effluent stream;
- and,
- passing the heated hydrocarbon effluent stream to the heat exchanger to heat the hydrocarbon feed stream and provide the pre-heated hydrocarbon feed stream.
