副产盐酸闭路循环吸收清洁生产工艺

Clean process of by-product hydrochloric acid production by closed circulating absorption

叙述了传统的降膜吸收工艺应用于循环吸收生产副产盐酸的不足之处,并有针对性地设计新的清洁生产吸收工艺,解决了循环吸收尾气的工艺难点,取得了显著的经济和社会效益。

The shortcoming of the traditional falling-film absorption process applied in by-product hydrochloric acid production by circulating absorption was put forward. When the new clean production process was design again to overcome these shortcomings, the difficulty of tail gas circulating absorption process was solved. Moreover, the remarkable economic benefits and social effects were obtained.
