摘　　要：介绍了硫酸系统尾气脱硫自动控制逻辑现状。针对系统存在的碱耗高等问题,提出了改造方案,并得到实际应用,取得了较好的运行效果。改造后,530 kt/a和300 kt/a制酸系统尾气脱硫耗碱显著降低,平均每月可降低碱耗115 t,降低脱硫成本约30万元。Present situation of automatic control logic of tail gas desulphurization in sulphuric acid system is introduced. Transformation schemes are put forward and applied in practice in terms of high alkali consumption in the system. By transformation, alkali con- sumption was decreased remarkably in tail gas desulphurization of 530 kt/a and 300 kt/a sulphuric acid plants, average alkali consumption was decreased by 115 t per month, and saved cost reached 300 thousand yuan every month.
