Abstract: In recent years, modular design and construction has been developing in petrochemical projects, including the design and construction of process units, which provides high-quality products and innovative development mode for project construction. Through the practice of modular design of petrochemical plants, this paper introduces the types of modules and the advantages of module construction, explores the implementation characteristics and requirements of modular design, as well as the challenges to the project and the prospect of future trend.

Key words: modular design, modular construction, module partition
