Thread Content

The 800,000 tons per year coal-to-olefins project of Xinjiang Shanneng Chemical Co., Ltd. in Wuciwan, Zhundong is being accelerated; it is currently in the stage where comprehensive construction drawings are being prepared simultaneously with tenders for the key equipment, with completion and operation planned for mid-2027. In February 2026, the project issued a series of key EPC/PC tenders covering synthesis, storage and transportation, utility systems, and auxiliary facilities: 1. EPC general contracting for the methanol synthesis unit (issued on 2026-02-26), tender number: SNZB-XJNH-D0100004044. Unit description: The methanol synthesis unit in this project uses the purified gas from upstream purification units and green hydrogen from electrolysis water units as raw materials. It employs Zhejiang Sinochem Wanfeng’s low-pressure methanol synthesis technology to produce MTO-grade methanol through processes such as syngas compression, methanol synthesis, methanol distillation, hydrogen recovery, and waste heat power generation. Qualified hydrogen is also produced as a by-product, while the waste heat from the synthesis reaction is recovered to generate steam for power production. Product scale: MTO-grade methanol (on a pure basis) of 2.2 million tons per year, corresponding to an hourly production capacity of 275,000 kg/h (based on 100% methanol). Core content: Full EPC service covering syngas compression, methanol synthesis, distillation, hydrogen recovery, and waste heat power generation; capacity of 2.2 million tons per year of MTO-grade methanol, utilizing Zhejiang Xuanshi Wanfeng’s low-pressure methanol synthesis technology, with integration of green hydrogen. Timeline requirement: 22 months, with intermediate handover conditions to be met by December 31, 2027. Qualification requirements: Class A design qualifications in the chemical, petrochemical, and pharmaceutical sectors are required, along with Class 1 construction qualifications for petrochemical projects; experience in EPC projects for methanol production of 1 million tons per year or more is necessary. Registration period: Files are available from 2026-02-26 to 2026-03-03, with the deadline on 2026-03-18. 2. EPC General Contracting for HDPE (High-Density Polyethylene) Plant (released on 2026-02-26). Key aspects: The LyondellBasell Hostalen ACP low-pressure slurry process will be used to build units for catalyst preparation, polymerization reactions, powder drying, and pellet homogenization, with the goal of producing high-performance HDPE specialty materials. Qualification requirements: Class A qualification in chemical engineering design plus Class 1 qualification for construction, along with experience in HDPE EPC or detailed design projects of 450,000 tons per year or more. Registration deadline: March 19, 2026. 3. General contracting of PC projects for the central control room, scientific research and testing building, etc. (released on 2026-02-28). Facilities included: central control room, scientific research and testing building, mechanical, electrical and instrumentation maintenance center, fire and gas protection station, PE/PP packaging warehouse, olefin vertical warehouse, and hazardous chemicals warehouse, etc. Milestone dates: The comprehensive warehouse, maintenance center, and chemical storage facility are to be completed by 2026-11-30 ； Control room, laboratory building – by 2027-06-30 ； Stereo warehouse by 2027-09-30. Qualification requirements: First-class qualification in construction engineering and mechanical & electrical engineering construction, with PC/EPC project experience worth over 100 million yuan in the past 5 years. 4. Phase 1 of the pile foundation works for the MTO facility (released on 2026-02-13). Scale: The contract value is estimated at 10.5 million yuan, with a construction period of 60 days; it covers the construction of key pile foundations for MTO and olefin separation processes. Deadline: Bid opening at 09:30 on 2026-03-06. 5. Public announcement on equipment procurement (2026-02). In addition, announcements were made on February 9th and 11th regarding the procurement of heat exchangers and towers (7 units); the tendering entity was Sinopec International Business Company Limited, confirming the progress in the procurement of these key equipment.
