摘要

In general, loading concentration of flammable gases between operating process is both imperative for reaction efficiency and necessary for hazard evaluation in the petrochemical industries. In fact, numerous petrochemical manufacturing processes react under high temperature, pressure, fuel, and oxygen concentration scenarios. Conventional steam pyrolysis is the prevailing technique for producing ethylene, and is known to be a non-catalytic, high temperature, as well as low pressure process that thermally cracks the reactant of ethane, propane, or liquid fuels. Therefore, we investigated the flammability limits and explosion pressures of ethane and ethylene under ordinary atmosphere environment, along with upper flammability limits (UFLs) tested within the upper operating limit (UOL) of pure oxygen condition via 20-L-Apparatus. We attempted to establish an empirical model for flammability limits and zone among two initial pressures (1 to 2 atm) and temperatures (approximately 30-200 C) inside the ethylene process for loss prevention concerns. The results showed that an empirical model of UFLs for hydrocarbons as a function of temperature was available; nevertheless, not available for the UOL scenario.
