In oil and gas production, corrosion caused by hydrogen sulfide can result in hydrogen induced cracking in susceptible steels. Hydrogen induced cracking is dependent upon the concentration of hydrogen in the steel matrix, and, therefore, the hydrogen flux through the steel. A novel, non-intrusive, rapidly portable, detector has been designed to measure hydrogen flux. The equipment has been applied to demonstrate the success of a corrosion inhibitor program in a wet sour gas gathering
system. Hydrogen emanating from the external pipe surface was continuously collected in a stream of air and conveyed to a remote hydrogen analyzer. The method enabled reliable measurement of
hydrogen flux within 1 minute to a resolution of ...
