The Safety Hierarchy states that hazards should be mitigated first by engineering controls, secondly by guarding, and lastly by warning/training. When the first two, engineering controls and guards, fail in a manufacturing setting, a chemical release could occur. A forensic chemical engineer can help determine the root cause of that failure.

Now that you know what ammonia is (see Part One here), how it behaves, and how to safely store it and work with it, let’s look at some areas in industry where it is used.
Anhydrous ammonia has a use in pollution control. Industrial boilers and power plants burn coal or natural gas to make steam and/or electricity. When the fuel is burned using air as the oxygen source nitrogen gets exposed to the heat as well because air is 79% nitrogen. The nitrogen gets oxidized and forms several compounds referred to as NOx (NO, NO2, NO3). NOx compounds are harmful to (more…)
Ammonia is a compound consisting of one nitrogen atom and three hydrogen atoms and is denoted by the formula NH3. Its boiling point is -28°F at atmospheric pressure, so unless it is under pressure, it is gaseous at room temperatures. Therefore, pure ammonia is typically stored under pressure in a liquid form. Household ammonia is only 5-10% NH3, the remaining 90-95% is water. Ammonia is extremely soluble in water. It is often depicted like this: (more…)
Warren is thrilled to announce that Jennifer Morningstar passed the Principles and Practice of Chemical Engineering exam and received her South Carolina Professional Engineer’s License on July 17, 2017. She has been with Warren since September 2011, in a non-engineering capacity but has rejoined the ranks of engineers as a consultant. (more…)
