In order to address the issue of water control in the production of high-purity nitrous oxide using ammonium nitrate decomposition method,this study investigates the effects of different equipment and different specifications of desiccants on water removal efficiency.Research has found that the process of producing nitrous oxide through thermal decomposition of ammonium nitrate uses ice water as the cold source for the condenser;The dryer uses 13X molecular sieve+alumina adsorbent;It can achieve stable water content in high-purity nitrous oxide below 0.5×10-6.This study investigated the equipment configuration and desiccant types in the production process of high-purity nitrous oxide using ammonium nitrate decomposition method,providing technical reference for the production of high-purity nitrous oxide.
