A modified version of the PRI was used to evaluate each case in order to incorporate safety considerations into the design process. These calculations were done following the method of Leong and Shariff [18], but the flow rate of each stream was incorporated as follows:

where mass flow rate (kg/h); HV_m, average mass heating value (kJ/kg); ρ, average fluid density (kg/m³); P, average pressure (bar); and ΔFL_mix, average explosiveness (%), where the explosiveness for each stream is given as the difference between UFL_mix and LFL_mix:
