摘要：NOVELTY - Recovering and converting reaction heat involves using wall heat exchange type saturation tower and its equipment. USE - For recovering transition and reaction heat from wall heat-exchanging type saturation tower, useful in synthetic ammonia and methyl alcohol production. ADVANTAGE - The method avoids the limitation of balance line when making direct heat exchange,thereby raising the 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. DETAILED DESCRIPTION - Recovering and converting reaction heat involves using wall heat exchange type saturation tower and its equipment. 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 effect heat exchange with conversion gas, catalytic reaction gas between conversion layers or hot water heated by catalytic reaction gas between conversion layers. An INDEPENDENT CLAIM is included for an equipment in which the above method is effected.
