Relationship between the temperature of ammonia water in the post-coker cycle and the pressure in the gas collection pipe.

There is a certain relationship between the temperature of the ammonia water in the post-coker cycle and the pressure in the gas collection pipe. Generally, as the pressure in the gas collection pipe increases, the temperature of the ammonia water in the cycle after the coke oven also rises, because the boiling point of ammonia water increases under high pressure, resulting in an increase in the heat of vaporization. Conversely, when the gas collector pressure decreases, the temperature of the ammonia water in the post-coke oven cycle drops. Furthermore, the temperature of the ammonia water in the post-coker cycle also affects the subsequent purification processes. For example, during the desulfurization process, changes in the temperature of the ammonia water in the post-coke oven cycle affect the reaction rate and the formation of reaction products, thereby influencing the efficiency of desulfurization. Therefore, controlling the changes in the temperature of the ammonia water in the post-coke oven circulation and the pressure in the gas collection pipe is crucial to ensuring the proper progress of subsequent purification processes. .

As mentioned above, \"when the pressure in the gas collection pipe increases, the temperature of the ammonia water in the cycle behind the coke oven also rises, because under high pressure the boiling point of ammonia water increases, resulting in an increase in the heat of vaporization.\" ” The pressure in the gas collection pipe ranges from 100 Pa to several hundred Pa; what impact does this have on the boiling point of ammonia water? Besides, what can the concentration of circulating ammonia water be? Around 2% – what kind of logic is that?
