What chemical inhibitor is added to unsaturated gas cargoes like Isoprene or VCM to prevent self-reaction?
Direct Answer
Option B: Polymerization inhibitor
Unsaturated cargoes like Isoprene or VCM are prone to hazardous, exothermic polymerization. IGC Code requirements mandate the addition of specific chemical inhibitors to stabilize these products. Monitoring inhibitor concentration is a critical safety task to prevent uncontrolled reactions that could lead to tank overpressure or catastrophic failure.
