摘　　要：唐山三友氯碱有限责任公司原来是根据外排浓硫酸浓度,控制浓硫酸高位槽的送酸量。存在分析滞后、测量精度低、自动化程度低、安全系数低的弊端。提出改变送酸方式、排酸方式和控制模式。改造后,能根据烧碱系统的负荷,及时调整浓硫酸使用量,降低生产消耗,提升自动化程度,提升生产安全系统,减少硫酸外泄事故。Tangshan Sanyou Chlor-Alkali Co.,Ltd.originally controlled the amount of acid discharged from the concentrated sulfuric acid elevated tank according to the concentration of discharged concentrated sulfuric acid.The original operation method had the following drawbacks:delayed analysis results,low measurement accuracy,low automation level,and low safety factor.The changes in the acid feeding method,acid discharge method and control mode were proposed.After transformation was done,timely adjustment of the usage of concentrated sulfuric acid could be realized according to the load of the caustic soda system,reducing production consumption,improving automation level,improving production safety system,and reducing sulfuric acid leakage accidents.
