Invest 21.88 billion yuan! The 1.2 million tons per year Phase II ethylene project at Dushanzi Petrochemical has passed the review. April 3, 2025 – Recently, the 90% scale model review for the green and low-carbon demonstration project associated with the 1.2 million tons per year Phase II ethylene production facility at China National Petroleum Corporation’s Dushanzi Petrochemical Company in Tarim was successfully conducted. The review session will first present and introduce the construction of the overall project model, and then verify and close out 60% of the model review comments one by one. Subsequently, the ammonia synthesis unit and the urea unit were grouped together to undergo a 90% model review simultaneously. During this review, the project team conducted thorough and detailed discussions with the owner on various aspects such as the layout of process pipelines in the model, the operation and maintenance of valves and equipment, the utility hose stations, process drain pipes, sampling and analysis pipelines, steam tracing stations, condensate recovery stations, sampling and analysis activities, underground facilities, fire protection systems, and electrical and instrumentation systems. Agreements were reached, and meeting minutes were prepared. It is understood that CNPC’s Dushanzi Petrochemical Tarim Phase II ethylene project mainly involves separating ethane from natural gas, and then producing ethylene through the cracking of that ethane. The approved investment for this project amounts to 21.88 billion yuan. Leveraging the abundant oil and gas resources in the Tarim Basin, it will build 11 main production units, including one unit capable of producing 1.2 million tons of ethylene per year, two units capable of producing 450,000 tons of fully dense polyethylene per year, and one unit capable of producing 300,000 tons of low-density polyethylene per year. The proportion of self-developed technology used in this project exceeds 99%, while the proportion of domestically produced equipment exceeds 98%.
90% model review: Should it be conducted internally? Will it be made public?
What does ‘internal’ mean? The Global Academy? Model review is essentially a design review conducted by the owner (and third parties hired by the owner) on the stage designs prepared by the design institute.
Feasibility studies, overall design, and basic design are reviewed by third parties (mostly from the industry), but for model reviews, it seems that no third parties (other than the client and the design team) have ever been involved in such processes
Yes, such as PMC, supervisors, and even key equipment suppliers, and so on.
CNPC operates mainly on an internal basis; there are no entities such as \"PMCs, supervisors, or even key equipment suppliers\"

So many parties need to be involved in the design kickoff meeting for a project’s utility island, not to mention the model review meeting for a large-scale project. This has nothing to do with internal or external factors of the company, but rather relates to the project stakeholders.
Maybe. I’m not sure if you work for a design firm affiliated with CNPC
There are differences in the purposes and participating organizations for kick-off meetings and model reviews
