1.苏尔维法制造程序为了更好地瞭解新法内容,必须先介绍旧法(苏尔维法)底情况及其优缺点。苏尔维制碱法、以饱和盐卤为起点,在盐卤中通入氨(NH_3),并尽量减除带入的水份,若采用液态氨,绝对没有增加水份。若用蒸铵塔蒸出来的氨,多少都带些水份,而普通蒸出来的氨,温度相当高,即用水来冷却,也不能低过55℃,因冷却下来,有其他的附带物体结晶出来,堵塞管道。所以通常总是在60℃左
1. Survival Law Manufacturing Procedures In order to better understand the contents of the new law, the status of the old law (Survival law) and its advantages and disadvantages must first be introduced. Survival soda method, starting from saturated brine, ammonia (NH_3) is introduced into the salt brine and the entrained water is minimized. If liquid ammonia is used, there is absolutely no increase in water. If the steam distilled ammonia column ammonia out, how much are with some water, and ordinary steam out of ammonia, the temperature is quite high, that is to use water to cool, it can not be lower than 55 ℃, due to cooling down, there are other incidental objects crystallization Out, plug the pipe. So usually always at 60 ℃ left
