A scrubber system was developed specifically to remove methyl bromide liberated during a demethylation process. On-line mass spectrometry (MS) was implemented and developed as a tool to monitor and quantify the methyl bromide scrubber efficiency during the demethylation reaction for laboratory and pilot-plant campaign runs. The MS technique is relatively simple to interface to existing equipment, requires
专门开发了一种洗涤器系统,用于去除去甲基化过程中释放的甲基溴。实施和开发了在线质谱 (MS) 作为一种工具,用于监测和量化实验室和中试工厂活动运行的去甲基化反应过程中的甲基溴洗涤器效率。MS 技术与现有设备的接口相对简单,不需要直接接触样品,并且允许从多个端口进行采样。实验室和中试工厂使用乙醇胺的 MS 在线监测结果表明,洗涤器去除效率 > 99%。除 MS 外,还实施了离子色谱法和其他重量分析法,以确认洗涤器消耗的甲基溴水平。
