摘要
为解决由于设计原料变化导致的重石脑油收率无法达到53%的设计收率、反应器床层冷氢开度过大、裂化反应器第三床层温升较高等问题,大榭石化2.0 Mt·a^(-1)工业燃料油加氢裂化装置采取大连石油化工研究院提供的催化剂级配技术,在未对装置现有工艺流程、设备改造的基础上,通过催化剂级配技术有效地改变装置的产品结构,对于市场需求可以灵活应对,调整后,既可以增产石脑油,以保证大榭石化的石脑油供应,又降低了冷氢开度,提高装置安全性。
In order to solve the problem that the heavy naphtha yield cannot reach the design yield of 53% due to the change of the design raw materials, the cold hydrogen opening of the reactor bed is too large, and the temperature rise of the three-bed cracking reactor is high, Daxie petrochemical company 2.0 Mt·a^(-1) industrial fuel oil hydrocracking unit adopts the catalyst grading technology provided by the Dalian research institute of petroleum and petrochemicals. On the basis of the existing process and equipment modification of the device, the catalyst grading technology is effectively used. It can respond flexibly to market demand. After adjustment, it can increase the yield of naphtha to ensure the naphtha supply of Daxie petrochemical company, reduce the opening of cold hydrogen, and improve the safety of the device.
