The effect of vacuum pressure on the flammability limits of hydrogen (H2) enriched liquefied petroleum gas (LPG) in a closed vessel

An experimental study on pressure explosion in 20-L closed vessel explosion unit of LPG–air –hydrogen mixtures was performed, for systems with various pressures evacuated. The objective of this research is to determine the correlation of vacuum pressure toward flammability limits of LPG H2 enriched....
