material balance for styrene butadiene rubber production

5 × 11,111 ≈ 8,333 kg/day Step 5: Account for Unreacted Monomers and Waste Assume 10% of monomers remain unreacted and are recovered or vented: Unreacted styrene: 0.10 × 2,778 ≈ 278 kg/day Unreacted butadiene: 0.10 × 8,333 ≈ 833 kg/day Remaining monomers in waste streams are thus: S
