Recently, the backup main fan unit K102 of the 3 million ton/year heavy oil catalytic cracking unit of the Anqing Petrochemical Transformation Project was successfully started, and the catalytic cracking unit has entered the comprehensive start-up stage.

The control room and on-site control personnel of the backup fan closely cooperate, carefully monitoring the operating conditions of the unit while observing and recording various parameters of the unit in detail. After on-site and operating room parameter comparison, the standby fan unit operates smoothly and all parameters meet the requirements of the plan. It was successfully started once, laying the foundation for the airtightness work of the catalytic reactor and regenerator in the next stage.

The 3 million t/a heavy oil catalytic cracking unit of Anqing Petrochemical Transformation Project is the first industrial application of RTC process core technology developed by Sinopec. The project has important leading and demonstration significance in addressing overcapacity in refining, exploring the transformation, upgrading, and high-quality development of fuel based refineries to chemical based refineries.

It is reported that the heavy oil catalytic cracking unit of Anqing Petrochemical has a total of three main fan units, namely two main units K101A/B and one backup fan unit K102. After the backup fan is successfully started and the two units have completed the relevant airtightness and other related processes, the K102 unit will be shut down, and the two main fan units K101A/B will enter the ignition furnace heating stage. It is expected that the overall start-up process will continue for more than 10 days. Editor/Xie Li
