Description

Though a number of firm offer aboveground storage tank (AST) leak detection services based on passive acoustics, very little information has been published concerning the performance of such systems or the nature of the acoustic leak signal. This document provides the results of an engineering assessment of passive-acoustic sensing methods for detecting small leaks in large ASTs. The assessment consisted of laboratory experiments, analyses of unpublished data collected by industry in a 10-foot-diameter AST containing water, and field experiments at the Mobil Oil Refinery in Beaumont, Texas on a 114-foot-diameter AST containing a heavy naphtha petroleum product.
