Abstract: To practice the principle of safety and precaution first, the anti-explosion and pressure-relief design of refinery buildings should be performed according to the fire hazard classification of dangerous goods used or produced during production, and relevant national standards and codes should be strictly followed to eliminate the potential safety hazards and ensure the normal operation of the unit. Several explosion-proof and pressure-relief design examples of refinery buildings are introduced including the selection of the main structure of buildings and the calculation of pressure relief area, so as to achieve the safety and rationality of design without waste of engineering material and additional investment

Key words: explosion-proof, pressure-relief, refinery building design
