NOVELTY - The process involves introducing a reformer feed gas mixture (15) into catalyst-containing reformer tubes in reformer furnace, to form reformate comprising hydrogen, carbonmonoxide, methane and water. The combustion product gas is introduced into a condenser (19), for cooling combustion product gas in condenser by indirect heat transfer with cooling fluid. A hydrogen-containing product is formed from reformate after reformate is heated the second water feed stream. One or more liquid water products are provided with liquid water stream withdrawn from condenser.    USE - Process for producing hydrogen-containing product and liquid water products, using salt water such as ocean water, seawater, and brackish water, surface water such as stream, river, or lake, groundwater, municipal/industrial reuse or recycled water, or waste water from industrial process.    ADVANTAGE - The hydrogen-containing product and liquid water products can be produced by eliminating or reducing the cost associated with rejecting the low level sensible heat from the combustion product gas to the atmosphere. The elimination or reduction in the amount of the sensible heat that needs to be rejected to the atmosphere before the water can be condensed out of combustion product gas can be enabled, thus the cost of the water recovery is reduced. The hydrogen production efficiency is improved. By eliminating one stage of heat exchange between the reformate and the raw water, the heat exchange temperature differences in the remaining heat exchangers is increased, and thus capital cost is reduced and thermal efficiency is improved.    DETAILED DESCRIPTION - The process involves combusting fuel with an oxidant gas in a combustion section of reformer furnace to form combustion product gas. First and second water feed streams are heated by indirect heat transfer with combustion product gas by cooling combustion product gas. Water feed streams are passed to de-aerator. The stripping dissolved gases from the first water feed stream and from the second water feed stream are in the deaerator, by withdrawing a vent stream from the de-aerator. The vent stream is set with steam and gases formed from the dissolved gases stripped from the first water feed stream and from the second water feed stream, and withdrawing boiler feed water stream from de-aerator. The boiler feed water stream is obtained with portion of the first water feed stream and portion of the second water feed stream.
