Project Overview

PetroChina has approved a final investment decision (FID) for a new multi-billion-dollar refinery and petrochemical complex in northeast China's Dalian. The project represents a strategic replacement of the company's aging 410,000 bpd Dalian Petrochemical refinery, which completed its closure in June 2025.

Operator and Ownership

PetroChina (through its parent company CNPC) will be the sole operator of the new refinery complex. The project is being developed as a direct replacement for the closed Dalian Petrochemical Corp facility, maintaining state ownership under the PetroChina umbrella.

Location Details

The new complex will be constructed on Changxing Island, approximately two hours' drive from downtown Dalian in Liaoning Province. The specific location is part of the Dalian Changxing Island (Xizhong Island) Petrochemical Industrial Base, which is being developed as a world-class green petrochemical industrial hub.

Project Capacity and Configuration

The approved complex comprises:

• Crude oil refinery: 200,000 barrels per day (bpd) capacity
• Ethylene complex: 1.4 million metric tonnes per year capacity
• Downstream units: Polyethylene, polypropylene, and polyolefin elastomer production

This represents a significant downsizing from the original 410,000 bpd capacity of the closed Dalian facility, reflecting China's shift from fuel production to higher-value petrochemicals.

The ethylene complex will likely employ steam cracking technology for olefin production, while the refinery will incorporate modern hydroprocessing units for producing both fuel products and petrochemical feedstocks.

Investment and Cost

The project carries an estimated total cost of 68.5 billion yuan ($9.56 billion). This substantial investment reflects the complex's integrated refining and petrochemical capabilities, along with the necessary infrastructure development on Changxing Island.

Construction Timeline and Start-up Schedule

Current Status: PetroChina has already begun preliminary infrastructure construction, including jetty and pipeline installation.

Projected Timeline:

• Construction Phase: Expected to span multiple years given the project's complexity
• Target Start-up: Based on similar projects and the scale involved, commercial operations are anticipated in the late 2020s to early 2030s

The timeline reflects the comprehensive scope of work required for both the refinery and integrated petrochemical facilities, along with supporting infrastructure on Changxing Island.
