The hydrogenation renovation project at Qilu Petrochemical was successfully commissioned. On May 11, the third cracking gasoline hydrogenation renovation project, which is one of the three key efficiency-improvement projects under Qilu Petrochemical’s “100-Day Effort to Improve Efficiency” initiative, was successfully put into operation. The project addresses issues such as the inability of fuel heating furnaces to operate at low loads by employing thermal cracking technology, primarily through the addition of a two-stage feed heater and the installation of a feed preheater, thereby reducing steam consumption and increasing production capacity. During the construction period, the company’s project team worked in close collaboration with the olefin plant project team, as well as Sinopec Energy Saving Technology Services Company and other construction and supervision entities, to work overtime and focus on quality improvement whenever the epidemic control situation allowed. On April 15, commissioning was achieved based on the control points; on May 9, inspections related to safety and environmental protection by relevant departments were passed; on May 10, all preparations prior to operation were completed; and on May 11, operation commenced successfully. Once put into operation, the device will achieve an energy savings rate of over 35%, with production capacity increasing by more than 60% on a year-on-year basis. At the same time, it will further expand the optimization potential of the three hydrogenation units, enabling long-term stable operation.
