Abstract:

Heating furnace is one of the important production equipment of petrochemical plant with high technical content and complex internal structure. With the large scale of petrochemical plants, the construction of heating furnace is developing from traditional bulk to modular. Taking the heating furnace of a certain refining unit as an example. Firstly, the heating furnace is divided into modules, and then the cost difference between modular and traditional bulk construction methods is compared and analyzed from three aspects of design, procurement and construction. It is found that the cost of modular construction saves 7.8 million yuan, compared with the traditional bulk construction method, saving ratio 10.18%. Moreover, modular construction shortens the construction period, reduces high-altitude operations, improves construction quality, and ensures the intrinsic safety of the heating furnace. The conclusion is that, under external conditions such as transportation and lifting, adopting a modular construction method for the heating furnace has significant promotional advantages.
