Anhydrous ammonia is commonly used in chemical plants and refineries for the production of fertilizers, plastics, fabrics, oil, etc. In these applications, ammonia should have a water content between 0.2% and 0.5% to avoid potentially critical product quality and corrosion issues. Testing should be performed routinely to ensure adequate water content. Any professional who is familiar with the task of taking ammonia samples knows what this process usually entails. First, you should put on the necessary personal protective equipment (PPE), including goggles, gloves, a respirator, and a chemical suit, to avoid exposure to ammonia vapors. Sampling is then carried out, a careful and rigorous process whose results may be imprecise due to small errors. In short, the entire process can take hours.
But it is possible to use more effective means for ammonia sampling. In this article, we will discuss why the laborious ammonia sampling process can be a drag on effective operation and how a sampling system designed specifically for ammonia analysis can help improve safety, accuracy, and reliability. efficiency of its facilities. The Traditional Ammonia Sampling Method Traditional BYB Directory ammonia sampling is commonly performed using the CGA G-2.2 method, in which a 100 mL sample of liquid ammonia is dispensed and then allowed to evaporate. The residual water from the evaporated sample provides a reliable way to measure the water content of the ammonia, hopefully within the desired range of 0.2% to 0.5%. If the water content falls outside this range, operators must take urgent measures to correct it.
Ammonia Stress Corrosion Cracking A water concentration less than 0.2% can increase the likelihood of ammonia stress corrosion cracking, and a water content greater than 0.5% is excessive. Accurate measurement of the water content in anhydrous ammonia is critical. If the water concentration is less than 0.2%, it may increase the likelihood of ammonia stress corrosion cracking in storage tanks or other parts of fluid systems that routinely contain this product. Stress corrosion cracking is a particularly dangerous phenomenon because it can destroy a component at stress levels below the tensile strength of an alloy. During the process, the phenomenon may be difficult to detect and the final failure may occur suddenly. On the other hand, a water content greater than the 0.5% threshold is excessive.
