摘要
克劳斯制硫转化器转化率计算常采用进、出口硫组分干基体积百分含量之差除以进口硫组分干基体积百分含量求得,由于没有考虑器内克劳斯反应时引起干气量的变化,使计算结果产生约0.9～3.7％的误差。本文引入“干精气”的概念,采用基准转换法推导出硫转化率计算式,与原式相比,只在原式后项乘上一个(1-A_x)/(1-B_x)的“体积校正因子”,使得硫转化率计算的依据更严格,结果更准确。
The conversion rate calculation of Claus sulfur-made convertor is obtained by using the percent-age content difference of dry base volume of sulfur component from inlet and outlet divided by the percentage content of dry base volume of sulfur component from inlet. Because of the change of dry gas quantity caused by the Claus reaction in the convertor is not considered, the error of calculation re-suit is about 0. 9~3.7%. This paper introduces the concept of 'dry refining gas' and using standard conversion method derives a sulfur conversion rate calculation formula. Comparing with the original one, its lost term is only timed((1-An)/(1-Bn))(volume correction factor)making the basis of sulfur conver-sion rate calculation more strict and the results more accuracy.
