Incorrect PV Issue Analysis :

• Normal operation setpoint: 1,200 kg/hr
• Actual flow rate (FE/FT): 2,600 kg/hr
• Difference (excess flow): 2,600 kg/hr – 1,165.82 kg/hr = 1,434.18 kg/hr
• Propylene gas cost: 1 kg = 34 THB
• Estimated annual operating hours: 24 hours/day × 350 days/year = 8,400 hours/year
• → Estimated cost saving opportunity:1,434.18 kg/hr × 34 THB/kg × 8,400 hrs/year = 409.6 million THB/year
