NOVELTY - Steam reforming (P1) of hydrocarbons involves heating boiler feed water; deaerating the heated boiler feed water; pressurizing the treated boiler feed water; heating the entire pressurized boiler feed water to near boiling temperature; feeding the portion of the high pressure heated boiler feed water to a high pressure steam unit; and sending at least part of the low pressure steam and the high pressure steam to at least one applications within the process for steam reforming or outside the process for steam reforming.    USE - For producing hydrogen (claimed).    ADVANTAGE - The process minimizes the equipment requirements and maximizes plant efficiency and reliability; and modifies the prior two level steam system by directing all of the boiler feed water from the deaerator and pumping it to the boiler feed water heater.    DETAILED DESCRIPTION - Steam reforming (P1) of hydrocarbons to produce hydrogen using a reformer, a water shift reactor, and a hydrogen pressure swing adsorption (PSA) and incorporating an integrated steam system for processing boiler feed water and steam, where the steam system is in fluid communication with the process for steam reforming, involves heating boiler feed water to form a heated boiler feed water; deaerating the heated boiler feed water to make a treated boiler feed water; pressurizing the treated boiler feed water to make a pressurized boiler feed water; heating the entire pressurized boiler feed water to near boiling temperature to produce a high pressure heated boiler feed water; separating the high pressure heated boiler feed water into at least a first portion and a second portion; feeding the first portion of the high pressure heated boiler feed water to a high pressure steam unit to make saturated boiler feed water to produce high pressure steam; feeding the second portion of the high pressure heated boiler feed water to a low pressure steam unit for making a low pressure steam; and sending at least part of the low pressure steam and the high pressure steam to at least one applications within the process for steam reforming or outside the process for steam reforming. INDEPENDENT CLAIMS are included for the following:    (1) a steam reforming system using the process (P1);    (2) a system for the steam reforming of hydrocarbons to produce hydrogen using a reformer, a water shift reactor, and a hydrogen PSA and incorporating an integrated steam system for processing boiler feed water and steam, comprising providing in fluid communication with the process for steam reforming a water heater, a deaerator (50), a boiler feed water heater (40), a low pressure steam unit, a high pressure steam unit, and a super heater (30), sending boiler feed water to a water heater, heating the boiler feed water and feeding the boiler water to a deaerator to make a treated boiler feed water, pressurizing substantially the entire stream of the treated boiler feed water to a pressure in excess of 300 psig to make a pressurized boiler feed water, feeding the pressurized boiler feed water to the boiler feed water heater, heating the pressurized boiler feed water to or near boiling temperature to produce a high pressure heated boiler feed water; feeding at least a portion of the high pressure heated boiler feed water to a high pressure steam unit to make high pressure steam, sending a discharge water stream from the high pressure steam unit to the low pressure steam unit, making low pressure steam in the low pressure steam unit and sending at least part of the low pressure steam to the deaerator, and sending at least part of the high pressure steam and part of the low pressure steam for use in at least one applications within the process for steam reforming or outside the process for steam reforming.
