加氢尾油作裂解原料的工艺参数对产品收率的影响

THE EFFECTS OF OPERATING PARAMETERS ON PRODUCT YIELDS WITH HYDROGENATION TAIL OIL AS FEEDSTOCK IN STEAM CRACKING

为更好地掌握加氢尾油作裂解原料的工艺参数，为装置工业化生产提供可靠的科学依据。对加氢尾油裂解性能的特性参数，包括原料氢含量、芳烃指数、族组成及特性因数等进行了评价，并对小试、工业试验数据进行了对比和分析，在理论和实际上探讨裂解温度（COT）、水油比和停留时间对主要产品收率的影响。提出了大庆加氢尾油作裂解原料时上述参数的最佳值。

Studies on the operating parameters with hydrogenation tail oil as feedstock to provide reliable scientific data for commercial steam cracking were conducted on a pilot plant. The characteristic paramters of cracking performance of hydrogenation tail oil, such as hydrogen content, aromatics index, group analysis and characteristic factor K, etc. were analyzed and evaluated. The effects of operating parameters including cracking temperature (COT), steam to oil ratio and residence time on product yields were investigated, and their optimum values for commercial operation are recommended.
