New progress has been made in the refining and chemical integration project of CNPC Dalian Petrochemical (Xizhongdao). The bidding process for the two tender lots in the preliminary investigation phase has been completed. New progress has been achieved in the refining and chemical integration project of CNPC Dalian Petrochemical Company (Xizhongdao). Recently, the bid openings for the preliminary surveys of the two project sections were held, and the first candidate selected as the winner was announced. As an important technical step in the early stages of project construction, the progress of preliminary survey work signifies further advancement in the preparatory work for the project. According to the announcement, this preliminary survey is divided into two lots. Bid Section 1 covers the refining area and the area in front of the plant, including the refining unit area west of the plant’s central axis, the raw material and intermediate tank areas, the product tank areas, the wastewater treatment facilities, the elevated flares, the thermal units, as well as the management area in front of the plant. The first winning bidder for this bid section is . A total of 715 drill holes were drilled, with an estimated footage of 42,066 meters. Lot 2 covers the chemical processing area and the utility systems, including the chemical processing units located to the east of the plant’s central axis, the chemical intermediate tank area, the storage and transportation area, the plant-wide warehouses and chemical storage facilities, as well as related utility areas such as air separation and air compression systems, the main substation, the circulating water system, and surface flares. The first winning bidder for this bid section is . A total of 649 drill holes were drilled, with an estimated penetration depth of 41,564 meters. The total number of boreholes for the two lots combined is approximately 1,364, with an estimated total drilling length of around 83,600 meters. Bids for this tender are submitted using a reduced fee coefficient. The maximum bid price for Bid Section 1 is 14.59 million yuan (including taxes), while that for Bid Section 2 is 14.42 million yuan (including taxes). In both cases, the discount rate is applied after a 55% reduction from the base pricing. The final contract price will be settled based on the actual amount of survey work carried out, and shall not exceed the approved investment amount. As required by the tender documents, the site survey must be completed within 1 month after the start of work on site, and the survey report must be submitted within 1.5 months. The survey results will provide a technical basis for the preliminary design of the project, the design of the equipment foundations, and the overall layout. The Nishinakajima refining and chemical integration project is an example of a large-scale domestic refining and chemical enterprise being relocated and rebuilt; the total investment amounts to around 68.5 billion yuan, with construction set to begin in 2026. The project plans to build a refinery with an annual capacity of 10 million tons and an ethylene plant with an annual capacity of 1.2 million tons, along with supporting facilities for storage, transportation, utility services, and auxiliary equipment. In terms of the layout of downstream products, it is planned to build 1 PP plant with an annual capacity of 400,000 tons, 2 FDPE plants with an annual capacity of 450,000 tons each, 1 LDPE plant with an annual capacity of 300,000 tons, 1 POE plant with an annual capacity of 200,000 tons, and 1 CHPPO plant with an annual capacity of 300,000 tons. The overall product structure will focus on olefins and high-end polyolefins. In terms of raw material composition, the project is designed to use \"70% Russian crude oil + 30% Saudi heavy oil\", and it has the capability to process 100% Russian crude oil. In the initial phase, all crude oil will be processed from Russia and transported to the plant via pipelines. The construction of some heavy oil processing facilities and the 300,000-ton crude oil terminal has been postponed; progress will be made at an appropriate time depending on the availability of crude oil resources. From the public announcements related to land reclamation to those regarding the opening of bids for this survey phase, all the preliminary work for the project continues to progress. As the survey work progresses, the subsequent preliminary design and project organization are areas that deserve attention.
