Ammonia World V3-01Understanding the Hazards and Potential Impacts of Ammonia Released to the Atmosphere

Thomas O. Spicer, PhD, PE

Ammonia is well known to be a toxic and also flammable material. The consequences of the loss of containment of ammonia depend importantly on its storage conditions (temperature and pressure) prior to release.  Ammonia released from pressurized storage has been shown to form an air/ammonia cloud which will be denser-than-air.  Ammonia released from refrigerated storage at ambient pressure can form an air/ammonia cloud which can be positively buoyant near the release point.  Denser-than-air materials behave quite differently from positively buoyant materials in releases to the atmosphere, and the consequences of a denser-than-air release are typically more significant than those of a positively buoyant release.  This paper discusses the importance of storage conditions (and quantity stored) on the potential consequences of an ammonia release from containment with regard to its toxic and flammable hazards.


Dr. Tom Spicer is Professor and Maurice E. Martin Barker Chair in Chemical Engineering at the University of Arkansas. He is a member of the AIChE Safety and Chemical Engineering Education (SAChE) Committee, the AIChE Education and Accreditation Committee, and is a Fellow of AIChE.  As Director of the Chemical Hazards Research Center, Tom’s primary research interests are in the assessment of hazards from airborne contaminants, particularly those that are denser than air.  Tom was a member of the Scientific Advisory Group that provided guidance to the Jack Rabbit II Test Program, a two year effort to assess consequences of chlorine released to the environment.


Process safety issues in ammonia production, storage and transport – A Process Safety perspective from India



The paper deals with an overview of the fertilizer industry in India, the process safety issues related to ammonia production, especially with plants of the older vintage, atmospheric storage of ammonia – process safety and security issues, and the risk involved in transportation of ammonia. A brief requirement of associated Indian regulatory requirements will also be discussed. Few incidents involved with ammonia production, storage and transport will also be discussed.

 State of the Art Ammonia Plants and Global Project Execution Capabilities

Robert Tikovsky

Nowadays we see an increasing demand for small and mid-scale ammonia plants. The reasons are manifold. High insurance cost for ammonia transport drive the local farm industry to “on site” production in the US where there is access to cheap shale gas or in other regions of the world where stranded gas is available. Other customers like the mining industry needs ammonia as a raw material for their on site production of explosives. Industrial complexes in the chemical industry often can accommodate a variety of products beside ammonia, like hydrogen, oxygen, nitrogen and CO2 or even sell them to the merchant market. These  scenarios are the economical sweet spot for the small- and mid scale plants.

Speed and easy implementation in geographies with hostile environmental conditions or a lack of qualified labor promote off site modularization in order to meet schedule and budget. EPC companies who have also a technology background and are able to combine adequate engineering tools with project execution capabilities can make these challenging projects a success.
