烃类热裂解的丙烯产率计算

The Calculation of Propylene Yield By the Thermal Cracking of Hydrocarbon

介绍一个新的预测丙烯产率的关联式。该式是以国内一些大型石化厂生产装置的运行操作数据为基础，采用经验法，同时考虑到原料组成和裂解操作条件两方面因素而得。并经逐步回归方法对参数的显著性进行检验。具有形式简单、参数易得、应用广泛及预测准确度高等特点。

A new correlation which predicts propylene yield is presented.Such equation is obtained not only based on the operation data in some large scale domestic petrochemical plants,but also applying the empirical method,and taking account of both the composition of raw materials and cracking operating conditions.The significance test is made to the parameters by the stepwise regression method.It is featured by simple form,extensive field of application and high accuracy,etc.
