摘要: 固定床渣油加氢装置由于受原料、操作条件等影响,催化剂更换周期一般是1-2年,无法与炼厂3-4年的检修周期匹配。渣油加氢单系列换剂开停工期间,部分含气体的油品退到罐区,造成环境污染并带来安全隐患。针对此问题,通过模拟分析,对两种开停工退油脱气流程的设备选型、投资及能耗进行对比,并提出流程选择建议。

Abstract: Affected by raw materials and operating conditions, the catalyst replacement cycle of fixed bed residue hydrogenation unit is normally 1-2 years, which cannot match the maintenance cycle of 3-4 years for refineries. During the startup and shutdown of a single train residue hydrogenation unit for catalyst replacement, some gas-containing oils are sent to the tank farm, causing environmental pollution and safety risks. To solve this problem, the equipment selection, investment and energy consumption of two degassing processes were compared with each other based on simulation analysis, and some suggestions were put forward for the selection of process.
