The aims of this study are to determine the flammability limits of LPG/ air mixture and to investigate the effect of nitrogen dilution on flammability limits of LPG/ air mixture at atmospheric pressure and ambient temperature. The experiments were performed in a 20 L closed explosion vessel. The mixtures were ignited by using spark permanent wire that placed at the centre of the vessel. The explosion pressure data is used to determine the flammability limits which flame propagation is considered occurred if explosion pressure greater than 0.1 bar. In this study, the result shows the flammability limits of LPG is from 2 % volume to 6 % volume of LPG and have revealed that the addition of nitrogen in LPG/air mixture reduce the upper flammability limit initially 6 % volume to 5 % volume of LPG. specialized Noraya Mohd Kadir Project paper (Bachelor of Chemical Engineering (Gas Technology)) -- Universiti Malaysia Pahang - 2010 Bibliography : p. 47-50 Nitric acids Nitrogen dioxide Photocatalysis THE0004700(Local) UMP 120312 20251114204516.0 vtls000058625
