Method and apparatus for removing carbon dioxide and water from syngas

The invention relates to a gas scrubbing method and apparatus for removing carbon dioxide (CO2) and water (H2O) from syngas, wherein the syngas comprises at least hydrogen (H2), carbon dioxide (CO2) and water (H2O). The invention features a dedicated circuit for removing water comprising scrubbing equipment for removing water by means of a physical absorption medium used in the gas scrubbing process. The absorption medium supplied to the washing equipment is removed from a thermal separation equipment for separating water and the absorption medium. The circuit is configured such that water entrained via the syngas to be purified cannot enter a main absorption medium circuit formed, in particular, by absorption equipment and regeneration equipment. The energy cost and equipment complexity, in particular with respect to the thermal separation equipment, are thus reduced. 本发明涉及用于从合成气中去除二氧化碳(CO2)和水(H2O)的气体洗涤方法和设备，其中该合成气至少包含氢气(H2)、二氧化碳(CO2)和水(H2O)。本发明的特征在于用于去除水的专用回路，该专用回路包括用于通过在该气体洗涤方法中使用的物理吸收介质来去除水的洗涤装备。将供应到该洗涤装备
