摘要
通过对焦化厂蒸氨系统直接蒸氨、间接蒸氨生产工艺装置的技术研究，选择合理工艺，使氨水中的挥发氨由约0．25％（2．5g／L）降至0．01％（0．1g／L）。
Through studying direct ammonia distillation process and indirect ammonia distiUation process in ammonia still system of the coking plant,the reasonable process was chosen, which decreased volatile ammonia concentration in ammonia water from 0.25% （2.5 g/L）to0.01% （0.1 g/L）.
