A process for producing a hydrogen-containing product and one or more liquid water products, the process comprising: (a) introducing a reformer feed gas mixture into a plurality of catalyst-containing reformer tubes in a reformer furnace, reacting the reformer feed gas mixture in a reforming reaction to form a reformate comprising H 2, CO, CH 4, and H 2 O, and withdrawing the reformate from the plurality of catalyst-containing tubes; (b) combusting a fuel with an oxidant gas in a combustion section of the reformer furnace external to the plurality of catalyst-containing reformer tubes to form a combustion product gas and generate heat to supply energy for reacting the reformer feed gas mixture inside the plurality of catalyst-containing reformer tubes, and withdrawing the combustion product gas from the combustion section; (c) heating a first water feed stream by indirect heat transfer with the combustion product gas thereby cooling the combustion product gas; (d) heating a second water feed stream by indirect heat transfer with the reformate withdrawn from the plurality of catalyst-containing tubes, thereby cooling the reformate; (e) passing the first water feed stream and the second water feed stream to a deaerator, the first water feed stream being passed to the deaerator after being heated by the combustion product gas, the second water feed stream being passed to the deaerator after being heated by the reformate, stripping dissolved gases from the first water feed stream and from the second water feed stream in the deaerator, withdrawing a vent stream from the deaerator, the vent stream comprising steam and gases formed from the dissolved gases stripped from the first water feed stream and from the second water feed stream, and withdrawing a boiler feed water stream from the deaerator, the boiler feed water stream comprising at least a portion of the first water feed stream and at least a portion of the second water feed stream; (f) introducing the combustion product gas into a condenser after the combustion product gas has been cooled by the first water feed stream, cooling the combustion product gas in the condenser by indirect heat transfer with a cooling fluid thereby condensing water from the combustion product gas to form a liquid water stream, separating the liquid water stream from a water-depleted combustion product gas stream, withdrawing the liquid water stream from the condenser, and withdrawing the water-depleted combustion product gas stream from the condenser; and (g) forming the hydrogen-containing product from the reformate after the reformate has heated the second water feed stream; (h) wherein the one or more liquid water products comprise the liquid water stream withdrawn from the condenser. (a) introducing a reformer feed gas mixture into a plurality of catalyst-containing reformer tubes in a reformer furnace, reacting the reformer feed gas mixture in a reforming reaction to form a reformate comprising H 2, CO, CH 4, and H 2 O, and withdrawing the reformate from the plurality of catalyst-containing tubes; (b) combusting a fuel with an oxidant gas in a combustion section of the reformer furnace external to the plurality of catalyst-containing reformer tubes to form a combustion product gas and generate heat to supply energy for reacting the reformer feed gas mixture inside the plurality of catalyst-containing reformer tubes, and withdrawing the combustion product gas from the combustion section; (c) heating a first water feed stream by indirect heat transfer with the combustion product gas thereby cooling the combustion product gas; (d) heating a second water feed stream by indirect heat transfer with the reformate withdrawn from the plurality of catalyst-containing tubes, thereby cooling the reformate; (e) passing the first water feed stream and the second water feed stream to a deaerator, the first water feed stream being passed to the deaerator after being heated by the combustion product gas, the second water feed stream being passed to the deaerator after being heated by the reformate, stripping dissolved gases from the first water feed stream and from the second water feed stream in the deaerator, withdrawing a vent stream from the deaerator, the vent stream comprising steam and gases formed from the dissolved gases stripped from the first water feed stream and from the second water feed stream, and withdrawing a boiler feed water stream from the deaerator, the boiler feed water stream comprising at least a portion of the first water feed stream and at least a portion of the second water feed stream; (f) introducing the combustion product gas into a condenser after the combustion product gas has been cooled by the first water feed stream, cooling the combustion product gas in the condenser by indirect heat transfer with a cooling fluid thereby condensing water from the combustion product gas to form a liquid water stream, separating the liquid water stream from a water-depleted combustion product gas stream, withdrawing the liquid water stream from the condenser, and withdrawing the water-depleted combustion product gas stream from the condenser; and (g) forming the hydrogen-containing product from the reformate after the reformate has heated the second water feed stream; (h) wherein the one or more liquid water products comprise the liquid water stream withdrawn from the condenser.
