In this process, AI first precipitates ammonium chloride crystals in a cold crystallization vessel; semi-mother liquor II is then fed into a salting-out crystallization vessel where more salt is added to precipitate further ammonium chloride crystals. The resulting crystal slurry is separated to isolate the ammonium chloride, and this entire process is known as the combined-material process.
In the A1 process, ammonium chloride crystals are first precipitated in a cold crystallization vessel; then, the semi-mother liquor 11 overflows into a salting-out crystallization vessel where more salt is added to precipitate further ammonium chloride crystals. The crystal slurry is taken out and subjected to thickening separation to isolate ammonium chloride – this process flow is known as the combined-material process.
The process in which AI first precipitates ammonium chloride crystals in a cold crystallization vessel, half of the mother liquor II is overflowed to a salting-out crystallization vessel where more salt is added to precipitate further ammonium chloride crystals, and the resulting crystal slurries are separately taken out and thickened to separate out the ammonium chloride is known as the combined-material process.
The process in which AI first precipitates ammonium chloride crystals in the cold crystallization vessel, half of the mother liquor II is fed into the salt crystallization vessel where more salt is added to precipitate further ammonium chloride crystals; the resulting slurry is then separated to isolate ammonium chloride is known as the combined-process flow
The process in which ammonium chloride crystals are first precipitated in a cold crystallization vessel, while semi-mother liquor II overflows into a salting-out crystallization vessel where more salt is added to precipitate ammonium chloride crystals, and the resulting slurry is then separated to isolate ammonium chloride is known as a co-current process.
In the AⅠ cold crystallization vessel, ammonium chloride crystals are precipitated; half of the MⅡ stream is diverted to the salting-out crystallization vessel where salt is added to precipitate ammonium chloride crystals. The slurry from each vessel is then separated to isolate the ammonium chloride, and this process is known as the combined-process flow

Answer: In this process, AI first precipitates ammonium chloride crystals in a cold crystallization vessel; semi-mother liquor II is then overflowed into a salting-out crystallization vessel where more ammonium chloride crystals are precipitated. The resulting slurry is separately taken out and thickened to separate the ammonium chloride, and this process flow is known as the combined-material process flow. hide] 1# chen3jun
In this process, AI first causes ammonium chloride crystals to precipitate in the cooling crystallizer; semi-mother liquor II is then fed into the salting-out crystallizer where more salt is added to induce the precipitation of ammonium chloride. The resulting crystal slurry is separated into different fractions through thickening processes.
In this process, AI first precipitates ammonium chloride crystals in a cold crystallization vessel; semi-mother liquor II is then transferred to a salting-out crystallization vessel where more salt is added to precipitate further ammonium chloride crystals. The resulting crystal slurry is separated to isolate the ammonium chloride, and this process is known as the combined-material process.
The process in which AI first precipitates ammonium chloride crystals in a cold crystallization vessel, while Half-Mu Liquid II overflows into a salting-out crystallization vessel where more salt is added to precipitate ammonium chloride crystals; the resulting crystal slurry is then separated to isolate ammonium chloride – this process is known as the combined-material process
