Ammonia Refrigeration Plant Risk Management Plan

I am developing an RMP (risk management plan as required by the U.S. EPA) for a client with an ammonia refrigeration plant of 250 tons per day refrigeration capacity. I need help in deciding whether or not the plant correctly handles their relief valve vents and their emergency release dump lines. Can any of you, involved with an ammonia refrigeration plant in the U.S of about the same size, help me with these questions:<br>
<br>
(a) How does your plant handle and/or route relief valve vents and emergency dump lines?<br>
(b) If your relief vents and emergency dump lines are routed into a water storage vessel, does it contain enough water to absorb 100 percent of your plant's ammonia inventory?<br>
(c) Is there some standard or code that governs how much water should be in such a water storage vessel?<br>
<br>
Thanks for any guidance you can give me. <p> Milton Beychok<br><a href=mailto:mbeychok@home.com>mbeychok@home.com</a><br><a href= Air Pollution Dispersion Modeling</a><br>Visit my URL to learn about "Fundamentals of Stack Gas Dispersion",<br>
