全球单体规模最大MTBE项目机械竣工

Core Insights - China National Chemical Corporation's subsidiary, China Tianchen Engineering Corporation, has completed the mechanical construction of the Saudi Sabic PKN MTBE project four days ahead of schedule, marking it as the largest single-unit MTBE plant globally [1] Group 1: Project Overview - The project was officially signed in November 2022 and commenced in December 2022, focusing on upgrading an existing 700,000 tons/year MTBE facility to a capacity of 1,000,000 tons/year [1] - The upgraded facility will significantly enhance economic benefits, environmental performance, and operational reliability, including the ability to generate 10 megawatts of electricity from low-pressure steam byproducts and reducing catalyst consumption by approximately 6,300 tons annually [1] - The operational downtime for the MTBE synthesis unit has been extended from 8 months to 2 years, improving overall efficiency [1] Group 2: Implementation Challenges - The project team faced multiple challenges in design, supply, construction, quality, and safety management, necessitating close collaboration with owners, suppliers, and subcontractors [1] - Real-time monitoring of design, procurement, and construction progress was implemented, along with strict control over on-site safety and execution quality [1] - Various measures were adopted, including optimizing international transportation routes, enhancing the prefabrication ratio of pipelines and steel structures, and implementing a "long-package" system for core procurement equipment, leading to the early completion of the project [1] Group 3: MTBE Characteristics - MTBE is known for its good miscibility with gasoline, low water absorption, and minimal environmental pollution, making it an effective gasoline additive with excellent anti-knock properties [2] - It improves gasoline cold-start characteristics and acceleration performance, with tests showing that gasoline containing 10% MTBE can reduce fuel consumption by 7% and significantly lower emissions of lead, carbon monoxide, and carcinogenic polycyclic aromatic hydrocarbons [2]
