The Liquefaction Link: A Chinese Centrifugal Propylene Compressor Running at the Million-Tonne CCUS Project
A domestically built centrifugal propylene compressor package is in continuous service at the Qilu–Shengli million-tonne CCUS demonstration, running the refrigeration cycle that liquefies captured CO₂ step by step.
Lead
A centrifugal propylene compressor package developed by Chongqing General Industry (Group) Co. (重庆通用工业（集团）有限责任公司) is in continuous operation at the Qilu Petrochemical–Shengli Oilfield million-tonne CCUS demonstration project, the China General Machinery Industry Association reported on 28 October 2026.
Facts
The duty. The compressor drives the propylene refrigeration cycle that liquefies the captured CO₂ in stages — the cooling link between capture and storage or use. (Source: the China General Machinery Industry Association, 2026-10-28.)
The project. The Qilu–Shengli project is China's million-tonne-class CCUS demonstration, pairing the petrochemical source with oilfield utilisation and storage. (Source: the same.)
The machine. The package is described as the group's self-developed centrifugal unit; the report notes its continued operation on site. (Source: the same.)
