摘要: This research investigated the influence of binary solutions benzene and methanol for their vapor flammability characteristics. The different mixing ratios (100/0, 75/25, 50/50, 25/75 0/100 vol%) samples were injected into a 20-liter spherical explosion vessel under various initial temperatures (100, 150 and 200°C) to study behaviors. According experimental results, diagram mixtures can be completely illustrated and combined with specific safety-related properties such as lower explosion limit (LEL), upper limit (UEL), minimum oxygen concentration (MOC), maximum overpressure (Pmax), and gas or deflagration index (Kg). The experimental results showed that UEL, Pmax and Kg all increased with temperature, pressure concentration, whereas there was no significant variation on part LEL. provide specific information fire hazards for related industries.
