ANSI/ASHRAE标准15-1989建议了一种从制冷厂释放氨时收集氨的程序，以提供安全释放到大气中的方法。该程序利用水作为捕集介质，并建议在接收容器中为每磅必须吸收的氨提供一加仑的静水。或者，该标准建议氨水混合器在每磅/分钟氨水2 gpm的条件下运行。由于该程序的实际性能未知，因此进行了实验，以评估该氨捕集器的有效性。实验研究了三种情况:（1）蒸汽氨被部分填充的水容器吸收，（2）液氨被部分填充的水容器吸收，以及（3）蒸汽氨被水雾吸收。 接收罐装有200加仑水，直径4英尺，高11英尺。实验确定了释放的200磅氨中有多少被水吸收。相对于ANSI/ASHRAE推荐的程序，大约90%的蒸汽氨被部分填充的容器吸收。随着液氨的释放，所有的氨都被部分填充的容器吸收。液氨吸收的增加是由于液体混合物温度较低。在涉及喷水的情况下，蒸汽氨流量和水流量设置为ANSI/ASHRAE建议的比率（每磅氨2加仑水），大约86%的氨被吸收。观察到水中截留的氨的解吸导致液体混合物中的氨浓度在50天内下降约2倍。

The ANSI/ASHRAE Standard 15-1989 suggests a procedure for trapping ammonia when released from a refrigeration plant to provide a means for safe release to the atmosphere. This procedure utilizes water as the trapping medium and recommends that one gallon of standing water in a receiver vessel be provided for every pound of ammonia that must be absorbed. Alternatively, the standard suggests that ammonia-water mixers operate under the conditions of 2 gpm of water per lb/min ammonia. Because actual performance of the procedure was unknown, experiments were conducted evaluating the effectiveness of this ammonia trap. Three situations were investigated experimentally: (1) vapor ammonia absorbed into a partially filled vessel of water, (2) liquid ammonia absorbed into a partially filled vessel of water, and (3) vapor ammonia absorbed into a water spray. The receiving tank contained 200 gallons of water and was 4 feet in diameter and 11 feet tall. The experiments identified how much of the 200 lbm of ammonia released was absorbed by the water. Relative to the ANSI/ASHRAE recommended procedure, about 90% of the vapor ammonia was absorbed in the partially filled vessel. With the release of liquid ammonia, all the ammonia was absorbed in the partially filled vessel. The increased absorption of liquid ammonia is due to the lower liquid mixture temperature. In the situation involving the water spray, the vapor ammonia flow and water flow rates were set at the ANSI/ASHRAE recommended ratio (2 gallons water per pound of ammonia) and approximately 86% of the ammonia released was absorbed. Desorption of ammonia trapped in water was observed to result in the decrease of ammonia concentration in the liquid mixture by a factor of about 2 in 50 days.
