Propylene yield from naphtha pyrolysis cracking using surface response analysis

The s‌tudy was conducted in the actual world-scale olefin plant with a focus on measuring the impact of identified controlled variables at the s‌team cracker furnace towards the propylene yield. Surface response analysis was conducted in the Minitab software version 20 using the his‌torical data aft...
