The present application belongs to the technical field of slurry bed hydrogenation, and discloses a residual oil processing system and method. The system comprises a residual oil hydrogenation reaction device, an oil-gas separation unit, an atmospheric distillation unit, a vacuum distillation unit and a raw oil feeding pipeline. The present application has the technical characteristics of simple structure, improved economic benefits, reduced investment cost and device operation energy consumption, etc.

The application discloses a combined core column plate and a one-time forming construction method thereof. The core column plate comprises, from bottom to top, a tension UHPC lower panel and a compression ordinary concrete or light-weight high-strength concrete upper panel, and the two panels are connected through a plurality of vertical combined core columns, and a shear key or a rough interface is arranged at the joint of the core column and the panel to ensure the cooperative stress. A polyurethane heat preservation inner mold is arranged between adjacent core columns, and the inner mold serves as a one-time permanent formwork and reserves a pipeline channel. The construction method is as follows: the UHPC lower panel and the lower section of the core column are poured in the same mold first, and then the upper ordinary concrete panel and the upper section of the core column are poured within a limited time interval, so that the wet joint is integrally formed. The application reduces the material cost on the premise of maintaining the high performance of the tension UHPC, and has the advantages of light weight, high heat preservation and being suitable for modular prefabrication.
