Abstract

A method and a system for producing synthesis gas, wherein process condensate is used to produce steam. To this end, steam is used to strip volatile impurities, in particular carbon dioxide, from the process condensate and then preferably convert the impurities together with flue gas and discharge them. Then a pH of at least 7.0 is preferably set by adding additives, the process condensate being evaporated and recycled as output steam for producing synthesis gas. In this way, it is possible to suppress the corrosive effect of the process condensate such that no, or less, corrosion-resistant stainless-steel must be used in the manufacture of the system components that come into contact with the process condensate. The steam used to strip the volatile impurities is preferably generated by heat from the synthesis gas and/or flue gas.
