焦化粗苯产率模型的建立

Build-up of crude benzol yield model

影响焦化粗苯产率的源头是原料煤和焦炉温度,对原料煤指标和焦炉温度与粗苯产率进行相关性分析,研究表明,粗苯产率与配合煤挥发分、炉温的相关系数较大,通过多元回归得到较准确的粗苯产率模型。

Because the source affecting the yield of coking crude benzol is the temperature of coke oven and raw coal property,so with the index of raw coal and coke oven temperature the correlation analysis is carried out to the yield of crude benzol.The result shows that the correlation coefficient between the yield of crude benzol and the VM of coal blend and oven temperature is larger,and a more accurate crude benzol yield model is obtained by multiple regression.
