Stage III Vapor Recovery Liquid Management: Engineering Practices to Keep the Return Line and Blower Free of Carryover

Why Liquid Megament in Vapor Recovery Lines Deserves More Attention A Stage III vapor recovery system only performs as well as its weakest branch, and in high-throughput stations that weak point is almost always liquid carryover. Gasoline vapor drawn back from the dispenser nozzle is rarely pure; it carries entrained fuel droplets, condensation, and the
