The synthesis-gas plant is operated in a number of successive operating periods such that during the first operating period an excess of fresh water is supplied to the synthesis gas plant and the waste water from the resulting mixture is separated in a condenser and supplied to a storage container. During the subsequent operating periods, the waste water stored in the container is used as the feed water for the synthesis gas plant and the waste water obtained on each occasion is stored in the container with increasing deuterium concentration. The waste water obtained during the last operating period and having the highest deuterium concentration is used to feed a plant for producing heavy water. This process, when used in a synthesis gas plant for producing hydrogen, can be used to obtain deuterium-enriched water as a feedstock for a heavy-water plant without expensive additional energy-consuming devices.
