Process Engineering Division – Instrumentation and Automation Section – Daily Question – Question from 2020-11-07: Discussion question: 289. Is there a risk of explosion for liquid ammonia in air? What is the lower explosion limit approximately?
If the concentration of ammonia in air is within the range of 5% to 15%, it can explode when exposed to an open flame, with a lower explosion limit of 5%.
Ammonia can explode when exposed to an open flame in air at concentrations ranging from 5% to 15%, with a lower explosion limit of 5%.
Liquid ammonia can explode in air: When the concentration of ammonia gas in the air is between 5% and 15%, it can explode upon contact with an open flame; however, it will not catch fire when the concentration is below the lower explosive limit, while it will catch fire when the concentration is above the upper explosive limit. The lower explosion limit for ammonia is approximately: 15.5% (by volume).
The lower explosive limit in air is 161% (φ). An explosion is possible, but it falls under Category B, which means it is only possible when dense white clouds are seen in a specific area.
