Protect Tanks from Overpressure and Vacuum | AIChE

API Standard 2000 defines the venting requirements for atmospheric and low-pressure storage tanks for both overpressure and vacuum. The standard covers causes of overpressure and vacuum, including additional scenarios to be considered for refrigerated tanks (Table 2) (2). Note that the causes of vacuum are often the inverse of analogous causes of overpressure.
