摘要
以宝钢股份能环部罗泾制氧厂4套6万m3/h空分装置自动变负荷控制技术为例,介绍空分装置自动变负荷过程中保持物料平衡和冷量平衡所涉及的相关物料、参与自动变负荷控制相关物料流量控制点的计算公式。通过对自动变负荷控制回路的控制功能图分析,说明空分装置自动变负荷控制技术的具体实施方法,总结空分装置自动变负荷技术长期稳定应用的经验,提出进一步优化的设想。
This paper took the example of the automatic load control technology installed in the 4 sets of air separation units with a capacity of 60 000 m3/h per unit at Luojing Oxygen Plant of Baosteel. It first introduced the materials relevant to keeping the material balance and coolant balance during the automatic load control and the calculation formula of the corresponding flow set points. Then the application of this technology was explained in detail, based on the function diagram analysis of the automatic load control loop. In the end, the experience in stable operation of automatic load control was summerized and personal views on further optimization were provided.
