High temperature shift converter
WebOne potential problem in the shift conversion operation is the formation of hydrocarbons by Fischer Tropsch reactions. This occurs primarily in the high-temperature shift converter and is favored by increasing CO/CO 2 ratio, decreasing steam/gas ratio, and increasing temperature (Hartye, 1985).Side effects of Fischer Tropsch reactions are the generation … WebChemical Engineering questions and answers. 210°C 360°C → High Temperature Shift Converter Low Temperature Shift Converter (0%co 3% CO emaining/ remaining Cky: 2.41 H. : 3u3:28 Na 14.46 CO: 26-19 CO: 67.19 T3 . 0 :27.03 The following reaction takes place in …
