Safety design analysis of LPG storage tank safety technical requirements

Liquefied petroleum gas is composed of hydrocarbons, the main components are propane, butane and other alkanes or alkenes. The combined percentage of propane plus butane exceeds 60%, below this ratio it cannot be called liquefied petroleum gas. Liquefied petroleum gas is a by-product obtained during catalytic cracking and thermal cracking in refineries. The main components of catalytic cracking gas are as follows (%): hydrogen 5~6. Methane10. Ethane 3~5. Vinyl3. Propane 16~20. Propylene 6~11. Butane 42~46. 5-6 butenes, 5-12 hydrocarbons with more than 5 carbon atoms.
