The propylene compressor is a key piece of equipment in the refrigeration and liquefaction units of the carbon capture process. Its main function is to provide cooling power for the liquefaction of carbon dioxide; it cools the gaseous carbon dioxide collected at the initial stage, converting it into liquid carbon dioxide that can be stored. This liquid carbon dioxide is then injected into underground oil fields to drive the extraction of oil. It serves as the \"heart\" of the entire project and plays a crucial role in the operation of the whole system. A large compressor was manufactured within just over 2 months, something that has never been done in the country before. Faced with immense delivery pressures, the entire staff at Chongtong adopted a round-the-clock, 5+2 work schedule to ensure quality, meet deadlines, and keep schedules on track. The technical team worked hard to resolve challenges related to solution design and component selection, resulting in a reduction of more than 60% in the time required for preparing technical documents. Product development and manufacturing were completed in just over a month, turning the impossible into possible and setting a new record for the shortest production cycle among large-scale compressor units in China. On December 10, the mechanical operation test of the propylene compressor was successful; the test data regarding vibration and temperature met all the design requirements. On December 12, the unit passed the on-site acceptance by the user, marking the successful completion of production of the propylene compressor unit, a key equipment for China’s first million-ton-scale CCUS project. It is understood that CCUS, short for carbon capture, utilization, and storage, is an important technical approach for addressing global climate change and controlling greenhouse gas emissions. It possesses great potential for emission reduction, and its applications in industry are promising. The Qilu Petrochemical CCUS project in which the company is participating is the largest CCUS industry-chain demonstration base in China. It will provide practical examples to **promote the scaled development of CCUS, and it also holds great significance for enhancing China’s capacity to reduce carbon emissions and establishing a carbon circulation model.
