Scott Brand Kill Gas

Used in Plastics Manufacturing

During plastic production, monomers polymerize to form long hydrocarbon chains through a continuous run. When a process upset occurs, the reaction must be stopped quickly to prevent the reactor from plugging with hardened plastics. For immediate termination of the reaction, kill gases are used. The chemical concentration of the kill gas depends on the polymer formed.

Recommended Manufacturing Applications

• Petrochemical
• Polypropylene
• Polyethylene
