Abstract (en)

[origin: WO2013182774A1] Process for producing hydrogen from a gas mixture comprising hydrogen (H2), and at least one impurity to be removed using an H2 PSA unit comprising N adsorbers subjected to a pressure cycle of duration T with N > 1, comprising the following successive steps: a) said gas mixture is introduced into said unit, b) at least one first stream enriched in hydrogen having an average impurity content Ypd is extracted, c) at least one second stream enriched in hydrogen having an average impurity content of Yhp is extracted, d) at least one third stream enriched in hydrogen having an average impurity content Ypd' is extracted, with Ypd > 3Yhp and Ypd' > 3Yhp.
