Abstract: This article takes the optimization and implementation of the equipment framework for a propane dehydrogenation unit as an example to introduce the characteristics of various framework structures and analyze the constraints of the equipment framework. The optimization is deepened according to the understanding of project characteristics and condition changes at different stages. The framework mainly considers the impact of load, spatial layout, and equipment vibration, changing the framework structure from the original all-steel structure in the basic design to a combination of partial steel structure and majority concrete structure. The key routes of these frameworks are identified as the reaction gas compressor and the dry gas compressor. On the basis of the in-situ cast concrete plan, it is further optimized to cast-in-place columns, prefabricated beams, and a composite roof structure, reducing the construction period from 9 months to 6 months. After the entire structural optimization was implemented, the project cost was reduced from the initially designed 40.47 million yuan to 31.10 million yuan, the construction period target was achieved, and positive effects such as framework equipment vibration reduction and construction safety risk reduction were obtained. Dynamic optimization of the plan and its implementation are key to achieving project goals.
