REFORMER ARRANGEMENT FOR PRODUCTION OF SYNTHESIS GAS AND/OR HYDROGEN

The invention discloses a reformer arrangement for production of synthesis gas and/or hydrogen, at least comprising the following elements: - a main reformer (1) connected to a main reformer reactant feed (2) and a main reformer product outlet (3); - a gas-heated reformer (GHR) (4) comprising a GHR reformer interior (4h) with GHR reformer tubes (4a) disposed therein, a GHR raw gas inlet (4b) connected to the GHR reformer tubes (4a); a GHR shell (4c) of the GHR reformer tubes (4a); a GHR main reformer product gas inlet (4d) connected to the main reformer product outlet (3) and the GHR shell (4c); a GHR product outlet (4e); - a heat transferrer (5) with a heat transferrer inlet opening (5a) and a heat transferrer outlet opening (5c), wherein a heat duct (5b) is disposed between the heat transferrer inlet opening (5a) and the GHR product outlet (4e); characterized in that the GHR product outlet (4e) is disposed in a plane parallel with the heat transferrer (5) and the height measured from the base up to the centre axis of the GHR product outlet (4e) is not more than plus/minus 20% the height measured from the base up to the centre axis of the heat transferrer inlet opening (5a).
