Is there a difference between ammonia absorption in the ammonia-alkali process and that in the double-alkali process? If so, in what aspects? Let’s talk separately about the principle of the ejector used for ammonia absorption in the caustic soda process: Working principle: The mother liquor is pressurized by a pump and then enters the nozzle through a converging tube, where it is ejected or discharged at the nozzle exit; at this point, potential energy is converted into kinetic energy. The flow rate of the mother liquor increases sharply, creating a negative pressure in the suction chamber; ammonia gas is then drawn in through the suction inlet ； When ammonia gas is under high pressure, it can more easily enter the suction chamber. After passing through the suction chamber, it mixes with the mother liquor and then enters the diffusion tube at a very high speed for thorough mixing and absorption. As the mother liquor absorbs the ammonia gas, its flow velocity decreases; the kinetic energy is thus converted back into potential energy. The ammoniated mother liquor is then discharged from the diffusion tube. Previously, the ammonia-soda process used ammonia absorption towers to absorb ammonia. Is jet-type ammonia absorption being used now as well?
