Abstract:
     The present invention belongs to the field of synthetic ammonia and methyl alcohol production, and discloses a method for recovering and converting reaction heat by means of dividing wall heat exchange type saturation tower and its equipment. It is characterized by that the charge gas and industrial soft water are fed into one side of heat exchange section of the dividing wall heat exchange type saturation tower to make heat exchange with conversion gas, catalytic reaction gas between conversion layers or hot water heated by catalytic reaction gas between conversion layers so as to avoid the limitation of balance line when making direct heat exchange, obviously raise steam-gas ratio of charge gas. For low conversion process, the steam-gas ratio can be up to 0.3-0.5, and for middle conversion process, the steam-gas ratio can be up to 0.65-0.80.
