Matthew Dixon – Swagelok

In order to avoid stress corrosion cracking in tanks, pipes, and vessels when handling anhydrous ammonia, the ammonia must contain a minimum water content. Verifying this water content involves an ammonia sampling operation that has traditionally posed concerns related to safety, emissions, and consistency. Swagelok has developed a closed loop sampler that solves these challenges and enables closed loop sampling of anhydrous ammonia in a safe and consistent manner.
