在热力学分析的基础上,计算了在Ga(CH3)3—AsH3—H2体系中在500K—1200K的温度范围内,可能的含砷及砷化物的形态和浓度.同时通过大量的模拟实验找出了去除尾气中砷的最好方法,还研制出用三级逆向喷淋法的治理设备,对尾气进行治理.治理后的尾气中砷的含量符合国家排放标准.
Based on thermodynamic analysis
the possible species containing arsenic and their concentrations at temperature from 500K to 1200K are calculated for Ga (CH3)3 - AsH3 - H2 system. A new method for arsenic abatement has been proposed through numerous simulation experiments. In order to improve the efficiency of arsenic abatement a three stage
counter flow showerbath has been inverstigated. The arsenic concentration in gases meets the State Standard for arsenic emission.
