Design and Engineering of Advanced Rail Stations and Storage Tank for ANS Handling.

REDD provided on-site and engineering support for a recently completed project in the Southwest area to install several new rail stations for offloading ammonium nitrate solution (ANS) and replace the aging main ANS storage tank with a new 43-ft-diameter tank having improved containment.

The new stations use compressed air to empty a railcar containing 100 tons of ANS in just 25 minutes. The ANS is offloaded from railcars directly into the new storage tank, eliminating the need for transfer pumps and reducing running costs.

With this new equipment in place, the plant can maintain operations regardless of supply chain disruptions and achieve regulatory compliance.
