Site Leveling Construction - First Bidding Section

Scope: Construction of the site leveling project for the northwestern area within the land acquisition red line of the Dalu 800,000 tons/year coal-to-olefins upgrade demonstration project (site leveling area approximately 137 hectares, maximum excavation depth approximately 15 meters). Main tasks include site clearing, earthwork excavation and transport, earthwork backfilling, surplus material disposal, layered compaction, dynamic compaction, retaining walls, and slope support.

Winning Candidate: Beijing Yanhua Tianzheng Construction Engineering Co., Ltd.

Site Leveling Construction - Second Bidding Section

Scope: Construction of the site leveling project for the southeastern area within the land acquisition red line of the Dalu 800,000 tons/year coal-to-olefins upgrade demonstration project (site leveling area approximately 165 hectares, maximum excavation depth approximately 15 meters). Main tasks include site clearing, earthwork excavation and transport, earthwork backfilling, surplus material disposal, layered compaction, dynamic compaction, retaining walls, and slope support.

Winning Candidate: Sinopec Shengli Construction Engineering Co., Ltd.

The Dalu 800,000 tons/year coal-to-olefins upgrade demonstration project of Sinopec Great Wall Energy and Chemical (Inner Mongolia) Co., Ltd. will adopt a full chain of Sinopec's proprietary technologies, including SE pulverized coal semi-waste heat boiler gasification, S-COS sulfur-tolerant shift, S-AGR acid gas removal, S-MS methanol synthesis, and Sinopec's S-MTO technology. The scale of methanol-to-olefins is 2.26 million tons/year (including OCC), with 350,000 tons/year of polyethylene, 450,000 tons/year of polypropylene, and 100,000 tons/year of EVA/LDPE.

In March 2023, Sinopec Great Wall Energy and Chemical (Inner Mongolia) Co., Ltd. won the coal exploration rights for the Nalin River Bayan Chaidamu mine field in Inner Mongolia Autonomous Region for 30.15 billion yuan. The mine is located in Uxin Banner, Ordos City, covering an area of 115.4319 square kilometers with coal resources of 2.131 billion tons. The planned production capacity is 10 million tons, providing raw coal supply for this project.

On July 8, 2024, the Dalu 800,000 tons/year coal-to-olefins upgrade demonstration project of Sinopec Great Wall Energy and Chemical (Inner Mongolia) Co., Ltd. initiated its environmental impact assessment.

The original entity responsible for constructing this project was CPI Mengxi Energy Co., Ltd., established in July 2014 as a wholly-owned subsidiary of SPIC Inner Mongolia Energy Co., Ltd. It was primarily responsible for investing in and constructing the Mengxi 800,000 tons/year coal-to-polyolefins project. This project received approval from the National Development and Reform Commission in August 2016 and was confirmed as one of the national-level planned coal-to-olefins upgrade demonstration projects designated by the NDRC. It was to be jointly constructed in partnership with France's Total Group.

Great Wall Energy and Chemical took over the original 800,000 tons/year coal-to-olefins project from SPIC Inner Mongolia Energy Co., Ltd. This project involves an investment of 23.8 billion yuan and includes the construction of a 2.2 million tons/year coal-to-methanol unit, a methanol-to-olefins unit, a 340,000 tons/year polyethylene unit, a 530,000 tons/year polypropylene unit, along with supporting utilities and auxiliary facilities. The main project includes key production units such as air separation, pulverized coal gasification, methanol synthesis, methanol-to-olefins, polyethylene, polypropylene, and sulfur recovery. The supporting utilities mainly include a thermal power station (using integrated gasification combined cycle technology), a water supply system, and storage and transportation systems (coal storage, product tank farm, silos).
