Abstract: A method for producing hydrogen by reforming hydrocarbons using steam, combined with carbon dioxide capture and steam production, which involves mixing the hydrocarbons to be reformed with steam in order to produce a feedstock for reforming, generating a syngas; the syngas produced is cooled, enriched with H2 and CO2, and then cooled; the condensates of the method are separated from the syngas in order to be used in the method, the saturated syngas being treated by adsorption with pressure modulation so as to produce hydrogen and a gaseous effluent containing CO2 that is captured in a CPU unit. The condensates from the cooling of the syngas at the outlet of the shift reactor are used in the method for producing impure steam supplying the mixing point; the CPU unit also produces CPU condensates that are recycled to be treated jointly with the condensates of the method.

The condensates of the method are separated from the syngas in order to be used in the method, the saturated syngas being treated by adsorption with pressure modulation so as to produce hydrogen and a gaseous effluent containing CO2 that is captured in a CO2-purifying unit. The condensates from the cooling of the syngas at the outlet of the shift reactor are used in the method for producing highly pure steam supplying the mixing point and for exportation; the CPU also produces CPU condensates that are recycled to be treated jointly with the condensates of the method.

Abstract: A method and apparatus for compressing a gas flowing comprising at least 0.1 vol % water, include a compressor containing N compression stages, in which each compression stage includes a compressing means and an exchanger directly or indirectly connected to a water-coolant circuit; and in which at least a first exchanger and a second exchanger, in first and second consecutive or non-consecutive compression stages, are connected in series to the water-coolant circuit. The exchangers, which are not connected in series to the water-coolant circuit, include at their water-coolant output a pressure drop device.

Abstract: The invention concerns receive circuitry for demodulating an input signal received from a transmission channel, the receive circuitry having a decision feedback equalizer including an inter-carrier interference estimation block arranged to provide an estimation of inter-carrier interference (ICI) noise based on at least a channel estimation determined for a previous symbol, a channel estimation determined for the next symbol, and on a previous estimation of the symbol data for the current symbol, the previous estimation being provided by a feedback path comprising a demapping block; and correction circuitry arranged to determine the estimation of the original data signal based on the estimation of ICI noise subtracted from the input signal.
