Light Hydrocarbons Bar 1024 18:30 Recently, the 400,000 tons per year light oil processing unit (ACO) of the Yanneng Chemical Project has successfully produced qualified ethylene and propylene products. To date, the main process of this device – including conversion, quenching, compression, cold separation, hot separation, and oxidation of waste alkali – has been established, marking a partial success. Construction of this project began on September 11, 2015; the installation was successfully completed by the end of 2017, and single-unit testing started in the first half of 2018. On September 2, the MTO and olefin separation unit were successfully started up for the first time! This unit is the first hydrocarbon catalytic cracking unit in China to date. ACO catalytic cracking technology replaces the traditional high-temperature steam cracking process by using catalytic reaction techniques to produce high-value materials such as ethylene and propylene at lower temperatures, thereby reducing energy consumption and CO2 emissions. It is reported that the ACO unit, as one of the key units in the energy expansion project, receives great attention from the group company. Since construction began in April 2016, facing complex manufacturing processes and a challenging geographical environment, the engineers of the ACO project team overcame difficulties head-on, constantly striving for new heights and achieving new breakthroughs. Ultimately, they successfully completed the project on schedule, earning high praise from the client. To date, all performance indicators of the device meet the expected standards; it operates smoothly, and the process parameters are within normal ranges.
