Description

technical field [0001] The present invention relates to a temperature and pressure tracking method for a simulated experimental device for emergency release of out-of-control chemical reaction in petrochemical industry, in particular to a design and type selection method for safety release device used for chemical reaction risk assessment and testing of petrochemical device Basic experimental data and a simulated experimental device for simulating the emergency release process when an out-of-control reaction occurs are required. Background technique [0002] Safety relief means that once overpressure occurs in the closed pressure equipment, the emergency relief device of the equipment will be opened automatically, so as to avoid unbearable explosion pressure inside the equipment. The uncontrolled chemical reaction is one of the important reasons for the overpressure of the equipment. If the design of the emergency relief device is unreasonable, the overpressure of the equipm...
