Mercury Measurement in Steel from Oil and Gas Operations without Damage or Harm

Yuping Li

Prompt Gamma Neutron Activation Analysis (PGAA or PGNAA) is a non-destructive essential analysis system potentially applicable for the non-invasive dimension of wall- bound mercury (Hg) deposited at trace situations on the process bathe face of sword pipe and vessels in oil painting and gas product and processing. Total wall- bound mercury, on 17 mercury- impacted sword pasteboard samples was measured by two non-destructive styles PGAA and XRF (X-ray luminescence spectroscopy). Following then on-destructive dimension styles, the samples were digested and anatomized by an infinitesimal luminescence Spectroscopy system grounded on the principles of EPA 1631 system (Acid Digest- AFS), generally considered state of the art for accurate mercury in sword measures. PGAA and XRF results were compared to those from the modified EPA 1631 system. Relative analysis of the results indicated that the PGAA measures displayed a trend fairly like that of the acid condensation- AFS system measures. Dimension delicacy, as determined by comparison to a “standard system” (Modified EPA 1631) wasn’t yet acceptable for quantitative dimension [1]. Still, the thickness in the shadowing of the PGAA results with results from the “standard system” along with derivate of a tone- attenuation correction factor suggests the eventuality for bettered delicacy and correlation. Details of the inter-comparison are handed herein.
