寻找氟氯化碳替代品的工作已经扩展到重新研究氨等现有制冷剂。任何合成氨厂都必须考虑的一个问题是适当控制向大气中的排放。此类释放可通过维修期间泄压阀、通风部件或子系统的排放，以及意外泄漏或溢出发生。大多数制冷剂专业人士认为，将氨直接排放到大气中是排放氨的首选方法。氨蒸汽强制分散的概念是以较高的向上速度将富含氨的混合物输送到空气中，以最小化顺风浓度，并提供在释放点用更多空气稀释氨/空气混合物的可能性。 该项目的目标是进行现场试验，测量涉及较大垂直向上速度的排放物顺风方向的氨浓度，并开发一个模型，供设计将氨分散到大气中的设备的工程师使用。主要研究者:唐纳德·芬顿，堪萨斯州立大学，主持:1994年4月至1998年11月，赞助:TC 10.1，定制工程制冷系统

The search for replacements for the CFCs has extended to revisiting established refrigerants such as ammonia. One consideration that has to be addressed in any ammonia plant is the proper control of releases to the atmosphere. Such releases can occur through the discharge of relief valves, venting components or subsystems during repairs, and unplanned leaks or spills. Most refrigerant professionals believe that the controlled release of ammonia directly to atmosphere is the preferable means of discharging ammonia. The concept of forced dispersion of ammonia vapor is to deliver the ammonia-rich mixture with a high upward velocity into the air to minimize the downwind concentration and to offer the possibility of dilution of the ammonia/air mixture with more air at the point of release. The objectives of this project are to perform field experiments measuring ammonia concentrations downwind from releases involving large upward vertical velocities and develop a model suitable for use by engineers designing equipment for dispersing ammonia into the atmosphere.Principal Investigator: Donald Fenton, Kansas State UniversityConducted: April 1994 -November 1998Sponsored by: TC 10.1, Custom Engineered Refrigeration Systems
