液体氨或氢氧化铵生产过程
Control of ammonia dilution in ammonium hydroxide, NH4OH生产过程
氨主要通过HABER工艺生产。原材料是天然气或燃料油(Naphtha),它为蒸汽重整过程产生氢(H2)。该过程分为五个步骤,包括去除硫,蒸汽改革,共同转化,净化和氨合成。
Vaisala K-Patents®process refractometer measures the concentration of liquid ammonia after dilution. Final concentration of ammonia is typically around 25% with measurement taken at ambient temperature. The refractometer can be easily calibrated either to read NH3(水中氨)或NH4OH(氢氧化铵)在水中。
折光仪提供以太网和4-20 mA输出信号,可用于自动控制稀释过程。
从应用笔记中学到了他详细介绍了液体氨产生过程。
