Is it necessary to install a safety valve on the gas line at the top of the carbonization tower for low-pressure synthesis of ammonium carbonate? Is it a safety valve or a burst disc?
Safety valves are generally used; but what should be done once a burst disc ruptures?
GB50160 specifies that a safety device must be installed when the pressure at the top of the tower exceeds 30 kpag. It is necessary to analyze the saturated vapor pressure at the temperature of the heat source and at the corresponding temperature of the medium being heated; if there is a risk of overpressure, such a device must be installed. The standards also require that a relief tank be provided for safe pressure release
