A process (10) for co-producing synthesis gas and power includes in a synthesis gas generation stage (12), producing a synthesis gas (50) comprising at least CO and H2 by reacting a hydrocarbonaceous feedstock with oxygen, the synthesis gas being at a first temperature. Air is separated in an air separation stage (16) from a compressed air stream by means of at least one ion transport membrane unit (16.1 ) thereby producing a permeate stream (42) consisting predominantly of oxygen and a reject stream (44) of oxygen-depleted air at a second temperature which is lower than the first temperature. The reject stream (44) of oxygen-depleted air is heated indirectly with the synthesis gas (50) and at least partially expanded through at least one turbine (28) to generate power, producing an at least partially expanded reject stream of oxygen-depleted air (54). At least a portion of the permeate stream (42) consisting predominantly of oxygen is fed to the synthesis gas generation stage (12) to provide oxygen for production of synthesis gas.

The invention discloses a nuclear power and low temperature multi-effect sea water desalination coupling cogeneration system, belonging to the technical field of nuclear power utilization and low temperature multi-effect sea water desalination. The system comprises a small-sized nuclear reactor, a vapor generator, a turbine, a vapor converter, a vapor thermal compressor, a low temperature multi-effect evaporator and auxiliary equipment.
