Ammonia sampler improves sampling safety and accuracy
Anhydrous ammonia is used in the production of fertilizers, plastics, textiles, petroleum and more. To avoid ammonia-stress-corrosion cracking in storage tanks and product quality concerns, the product must be regularly sampled to verify a water content of 0.2 to 0.5%. This company’s ammonia sampler (photo) has been specifically designed to address the issues inherent to manual sampling by utilizing closed-sample fixtures that improve safety by limiting operator exposure and minimizing environmental impact from excess emissions. It also employs residue tubes that are pre-chilled using the cold ammonia itself, thus preventing aggressive boiling that threatens fill accuracy. The system also has features that help to control the dispensing of the ammonia sample and ensure a consistent sample size. Other features include a single handle for easier operation and reduced operator error and a touchscreen interface to control all heater operations. Hall 8, Stand C77 — Swagelok Company, Solon, Ohio
