Reference method for measuring emissions of vinyl chloride from manufacturing: part III C-3

Part III - Calculations: Method C-3

Calculation of Reactor Opening Losses from Polyvinyl Chloride Plants

• C-3.1 Scope
• C-3.2 Calculation of Reactor Opening Loss

C-3.1 Scope

The calculation to compute the emissions of vinyl chloride resulting from reactor opening losses is described.

C-3.2 Calculation of Reactor Opening Loss

The emission rate of vinyl chloride resulting from a reactor opening shall be calculated using equation C-3-1.

• ER_vc/pvc = mass emission rate of vinyl chloride per production of polyvinyl chloride, kg VC per 100 kg PVC
• C_b = concentration of vinyl chloride in sample, ppm
• V_r = reactor volume, m³
• W = total weight of polyvinyl chloride resin produced since last opening, 100 kg
• 2.56 × 10^-6 = conversion factor, ppm vinyl chloride to kg/m³ at 25°C and 1 atm
