| 摘 要： | 比较了某石化公司两套不同丙烷脱沥青装置的工艺流程、核心设备、技术特点及运转效果，在使用相同原料和相同溶剂的条件下，采用美国KBR公司ROSE技术的装置的丙烷脱沥青油收率明显高于采用传统丙烷脱沥青工艺的装置，主要是由于ROSE工艺采用高效规整填料构件、两段产品工艺和大剂油比操作方案；两两套装置的脱沥青油性质差别不大。对于两套装置，均需要调整萃取塔塔顶温度和剂油比，兼顾脱沥青油质量与收率，使之达到良好的平衡。

COMPARISON OF TWO PROPANE DEASPHALTING UNITS ON YIELD AND PROPERTIES OF DEASPHALTED OIL |
| |
| Abstract: | The process flowsheets and technical features of the core equipment of two different propane deasphalting units of a petrochemical company.were analyzed and compared in terms of DAO yield and its quality under the conditions of the same feed and solvent. No large difference in properties of DAOs was found for the two devices. However, the temperature at the top of the extractor and solvent-oil ratio are all needed to be adjusted to get good balance of quality and yield. On the other aspect, the commercial results indicate that the device adopting ROSE technology from US KBR Company has a higher yield, as the ROSE technology uses high efficiency structured packing components, two stage process and larger solvent to oil ratio. |
