Abstract: In recent years, explosion accidents occurred frequently in the storage of hydrogen peroxide, so it is necessary to improve the intrinsic safety of its storage based on the thermal decomposition explosion characteristics of hydrogen peroxide. This paper presents the intrinsic safety design of hydrogen peroxide storage in a project. From the aspects of unit volume specific surface area, temperature rise of self-accelerating decomposition reaction, safety distance and discharge area, heat dissipation, etc., the process parameters of hydrogen peroxide storage are determined through two levels of design and calibration in order to reduce the risk of thermal explosion and to meet the requirements of intrinsic safety.

Key words: hydrogen peroxide, storage, intrinsic safety
