Soap Bubbles . the potential leak sites to determine if any bubbles are formed . If no bubbles are observed , the source is presumed to have no detectable emissions or leaks as applicable . If any bubbles are observed , the instrument techniques of Section 8.3.1 or 8.3.2 shall be used to determine if a leak exists , or if the source has detectable emissions , as applicable .
Final Thoughts
As can be seen , each component has its own specific section written into how to properly monitor it , per Method 21 . Although this test method is very detailed in explaining how to monitor each interface , leaks are still getting missed . So why is that ? Truly it is all about the speed , angle of the probe to the leaking interface , and making sure that the probe is truly on the leaking interface . By understanding the test methods , and specifically the monitoring locations , an operator or monitor will be able to more effectively find and address the present leaks . With a more comprehensive understanding of Method 21 , the addition of Certified Low Leaking Technology , and the advancements of the standards associated with API 622 , API 624 , API 641 , ASME 16.20 , and ISO 15848 , individuals will be better able to achieve a true reduction in emissions .
