天然气净化厂 Claus 硫磺回收装置硫回收率计算方法

摘要

介绍了天然气净化厂 Claus 硫磺回收装置硫回收率的主导计算公式和带尾气处理装置的总硫回收率计算方法，重点讨论了 Claus 硫磺回收装置硫回收率主导计算公式中硫磺在尾气中体积分数的确定方法及用氮平衡、碳平衡和硫平衡确定尾气流量的方法。%The main calculation formulas of sulfur recovery rate for Claus sulfur recovery unit were introduced,and the calculative methods of total sulfur recovery rate for sulfur recovery unit with tail gas treatment were also presented.The determination of sulfur volume contents in tail gas and tail gas flow rate by calculating the nitrogen balance,carbon balance and sulfur balance were discussed de-tailedly.
