Powdered ammonium chloride is a commonly used ammonium chloride product, which is widely used and has important application value in various fields. There are many kinds of production processes of powdered ammonium chloride, and each process has its unique technical characteristics. The following briefly introduces several commonly used powdered ammonium chloride production processes and their technical characteristics.
Solution crystallization method Solution crystallization method is one of the commonly used processes to produce powdered ammonium chloride. The process generally includes ammonia evaporation, stirring, open-air crystallization, centrifugal separation, drying and other steps. The characteristics of the process are as follows:
Simple and feasible: The solution crystallization method is simple to operate, and the equipment and process flow are relatively simplified, so it is easy to implement.
Wide applicability: The solution crystallization method is suitable for various scales of production and can produce powdered ammonium chloride products of different purities.
Good crystallization effect: the solution crystallization method can control the crystallization process and obtain a highly pure powder ammonium chloride product.
Low energy consumption: solution crystallization does not require high temperature and high pressure conditions, and the energy consumption is relatively low.
The gas-solid process is a method of producing powdered ammonium chloride by the reaction of ammonium chloride gas with other gases. Its main features are as follows:
Strong controllability: The gas-solid method can control the output and quality of powdered ammonium chloride by controlling the gas concentration of ammonium chloride, reaction temperature, air flow rate and other parameters.
Recyclable: The waste gas generated by the gas-solid reaction can be treated and recycled to reduce the waste of resources.
High efficiency and energy saving: the gas-solid method uses waste gas to react, which can improve energy utilization efficiency and achieve the purpose of energy saving.
Strong adaptability: the gas-solid method is suitable for production of different scales and conditions, and can be adjusted and improved according to needs.
Synthesis is a method of synthesizing ammonium chloride by chemical reaction. The commonly used synthesis processes are Bayer process, ammonia process and so on. Its technical characteristics are as follows:
Easy to control the reaction conditions: the synthesis method can adjust the reaction temperature and pressure according to the need to control the reaction conditions, so as to obtain the powdered ammonium chloride that meets the requirements.
Fast reaction speed: The synthetic method has a faster reaction speed and can achieve large-scale continuous production.
Quality stability: The synthesis method can ensure the stability of product quality by controlling the reaction conditions and the quality of raw materials.
The production process is relatively complex: the synthesis method needs to control the reaction conditions, and also needs supporting equipment and processing systems, so the production process is relatively complex compared with other processes.
The above are several commonly used powdered ammonium chloride production processes and their technical characteristics, different production processes have different scope of application and advantages and disadvantages, enterprises in the selection of production processes should be based on product demand, process requirements and economic benefits for comprehensive consideration.
