【摘要】 计算了合成氨的变换工序在一定条件下饱和热水塔循环水量、饱和塔和热水塔理论塔板数及变换系统蒸汽耗量。结果表明，系统在一定条件下存在一较为适宜的循环水量，且此适宜的循环水量随变换反应汽气比的降低而降低。更多还原

【Abstract】 A calculation is made of the quantity of circulating water in the saturation and hot water towers under certain conditions, the number of theoretical plates in the towers and steam consumption in the shift system in the shift conversion section of the ammonia plant. The results show that an appropriate quantity of circulating water exists under certain conditions in the system and decreases with a reduction in the steam gas ratio of the shift reaction.更多还原
