| Abstract: | The progress of NHD process for H2S and CO2 removal in methanol production is described. For H2S removal from raw materials with different sulfur contents, the technology of three towers combined with two-stage flashing and two towers combined with two-stage flashing have been adopted. In addition to the improvement of the stripping method, energy conservation process and the new atmospheric pressure desorption stripper have been adopted for CO2 removal. Practice shows that adopting NHD process in methanol production is high in efficiency and energy saving. |
