Chemical storage coefficient
Thread Content
Is the storage coefficient for general chemical storage tanks 0.9 or 0.85? Are there any relevant sources? Thank you!
Clause 4.2.2 of GB18218-2018 stipulates that the actual quantity of hazardous chemicals in storage tanks, as well as in other containers, equipment, or storage areas, shall be determined based on the maximum designed quantity. GB50160-2008, 2018 edition, 6.3.9: The storage coefficient for tanks storing liquefied hydrocarbons, liquid ammonia, etc., shall not be greater than 0.9 ； According to Clause 31.13 of TSG21-2016 regarding the filling coefficient, pressure vessels used for storing liquefied gases shall have a specified design storage capacity, and the filling coefficient must not be greater than 0.95.
Either one is fine; it’s not mandatory – it depends on the specific usage scenario
