Purging and inerting large-volume tankage and equipment-jet mixing concept-Part 2

Recommendations for the design, installation and testing of jet mixing systems

Gollin, M., Carmagen Engineering, Inc.

Part 1 of this article discussed the need for inerting or purging, the concept of minimum oxygen concentration (MOC) or limiting oxidant concentration (LOC) and general issues of concern. Simplified discussions of the methods usually used to inert or purge tanks and systems were provided.1,2 In Part 2 of this article, the use of jet mixing for inerting and purging large vapor volumes is discussed in detail. Jet mixing. As discussed in Part 1 of this article, inerting large vapor volumes using conventional inerting processes can be problematic. This can be demonstrated by Fig. 1 where a large tank is shown where nitrogen is introduced at the roof at a "low" velocity. At a low velocity, the
