Ammonia Vapor Equalization Header Project

■ Business Case: The current tank equalization header has a drop leg in the lines, where liquid can get trapped and build up pressure. The replacement line has the header spanning overtop the tanks, which will provide better equalization and safer operation.

■ Project Scope: Participating in daily pre-job briefs, ordering materials, and creating Purge & Repair plans.

■ Lessons Learned: Being Flexible

Ammonia Vapor Eq. Header ProjectPurge and Repair Plans

■ Header is to be implemented in 3 Stages, – Stage 1 – Spade Flange (pancake) on each tank where header attaches.

– Stage 2 – Put a high-point vent on 2A and 2B Tank Truck unloading lines.

– Stage 3 – Tie Header into system.
