Calculation of discharge volume under fire conditions
Thread Content
There is a 100-cubic-meter fixed-roof tank located in the tank farm. Its design pressure is 1 kg/cm², and the tank roof is equipped with a pressure relief device. When calculating the relief rate under fire conditions, should API 2000 or API 521 be referenced? Please, fellow forum members, discuss this among yourselves.
When calculating the discharge volume under fire conditions, calculations should be carried out in accordance with API 2000. This is because API2000 is primarily used to calculate the pressure and vacuum relief capacities of storage tanks, while API521 is mainly used to calculate the explosion and fire relief capacities within storage tanks. Therefore, in this problem, API2000 should be used for the calculations. .
The breather valve or emergency relief manhole shall comply with API2000, while the safety valve and rupture disc shall comply with API521
