A method of providing hydrotreated naphtha feedstocks to a refining reforming unit, the method being characterized by the steps of: directly integrating a naphtha stripping process section with a naphtha splitting process section, the direct integration comprising: providing a process-to-process heat exchanger unit receiving a bottom stream product of heavy naphtha from a naphtha splitter and a bottom stream product from a naphtha stripper, the bottom stream product from the naphtha stripper providing heat energy to the bottom stream product from the naphtha splitter, wherein the process-to-process heat exchanger unit is a first reboiling process-to-process heat exchanger unit configured to transfer heat from bottom stream product from the naphtha stripper to bottom stream product from the naphtha splitter; providing a second reboiling heat exchanger unit operably positioned to receive additional bottom stream product from the naphtha stripper and additional bottom stream product from the naphtha splitter so that the additional bottom stream product from the naphtha stripper provides heat energy to the additional bottom stream product from the naphtha splitter to reboil the additional bottom stream product from the naphtha splitter; providing a fired heater unit operably positioned to reboil bottom stream product from naphtha stripper; conducting the reboiling of the bottom stream product from the naphtha splitter utilizing naphtha stripper bottom stream product from the naphtha stripper, the reboiling conducted utilizing the first and the second reboiling process-to-process heat exchanger units (81, 91), optionally wherein the first and the second reboiling process-to-process heat exchanger units (81, 91) are collectively configured to provide sufficient heat exchange capacity to reboil the bottom stream product from the naphtha splitter without use of a fired heater unit positioned to directly reboil the bottom stream product from naphtha splitter, the naphtha splitting process section being devoid of a fired heater unit; providing the heavy naphtha bottom stream product from the naphtha splitter as a reforming feed to a refining reforming unit. directly integrating a naphtha stripping process section with a naphtha splitting process section, the direct integration comprising: providing a process-to-process heat exchanger unit receiving a bottom stream product of heavy naphtha from a naphtha splitter and a bottom stream product from a naphtha stripper, the bottom stream product from the naphtha stripper providing heat energy to the bottom stream product from the naphtha splitter, wherein the process-to-process heat exchanger unit is a first reboiling process-to-process heat exchanger unit configured to transfer heat from bottom stream product from the naphtha stripper to bottom stream product from the naphtha splitter; providing a second reboiling heat exchanger unit operably positioned to receive additional bottom stream product from the naphtha stripper and additional bottom stream product from the naphtha splitter so that the additional bottom stream product from the naphtha stripper provides heat energy to the additional bottom stream product from the naphtha splitter to reboil the additional bottom stream product from the naphtha splitter; providing a fired heater unit operably positioned to reboil bottom stream product from naphtha stripper; conducting the reboiling of the bottom stream product from the naphtha splitter utilizing naphtha stripper bottom stream product from the naphtha stripper, the reboiling conducted utilizing the first and the second reboiling process-to-process heat exchanger units (81, 91), optionally wherein the first and the second reboiling process-to-process heat exchanger units (81, 91) are collectively configured to provide sufficient heat exchange capacity to reboil the bottom stream product from the naphtha splitter without use of a fired heater unit positioned to directly reboil the bottom stream product from naphtha splitter, the naphtha splitting process section being devoid of a fired heater unit; providing the heavy naphtha bottom stream product from the naphtha splitter as a reforming feed to a refining reforming unit.
