FIELD APPLICATION OF A NEW, PORTABLE, NON-INTRUSIVE HYDROGEN MONITOR FOR SOUR SERVICE

摘要

In oil and gas production, corrosion caused by hydrogen sulfide can result in hydrogen inducedrncracking in susceptible steels. Hydrogen induced cracking is dependent upon the concentration ofrnhydrogen in the steel matrix, and, therefore, the hydrogen flux through the steel. A novel, non-rnintrusive, rapidly portable, detector has been designed to measure hydrogen flux. The equipment hasrnbeen applied to demonstrate the success of a corrosion inhibitor program in a wet sour gas gatheringrnsystem. Hydrogen emanating from the external pipe surface was continuously collected in a stream ofrnair and conveyed to a remote hydrogen analyzer. The method enabled reliable measurement ofrnhydrogen flux within 1 minute to a resolution of ±2 picoliters/cm~2/s.
