延迟焦化分子尺度动力学模型的工业应用

将延迟焦化分子尺度动力学模型应用于中国石油化工集团高桥石化分公司延迟焦化装置中,以工业标定数据为依据,对焦化原料油及焦化产物的产率分布进行了模拟。结果表明:原料油模拟生成的分子数在1 000~5 000,能够很好地反映原料油的性质;当原料油模拟生成的分子数为4 000时,产物产率的稳定性较好,相对误差都较小,模拟过程能较好地反映实际工业情况,说明该模型具有较好的实用性及可靠性。

Industrial Applications of Molecular Scale Kinetic Model in Delayed Coking

Based on the industrial rating data,a molecular kinetic model of delayed coking was used to simulate the feedstock and products in a delayed coking process in industrial reactors in Gaoqiao Petrochemical Co.of China Petroleum & Chemical Corporation.When the number of generated molecules is(between) 1 000 and 5 000,these molecules reflect the characters of feedstock very well.When the mole-(cule number) is 4 000,the process is more stable and the relative error of products is smaller.It was also(shown) that the model does reflect actual conditions well.
