Methods of generating and corrosion testing aqueous gas streams prepared from aqueous acid and salt precursor solutions

Abstract

Embodiments of methods for producing and testing aqueous gas streams within a self-pressurized flow cell are disclosed. The aqueous gas streams comprise mixtures of aqueous salt precursor and aqueous acid precursor that are mixed in-line and introduced to the self-pressurized flow cell to produce aqueous gases. Once in the self-pressurized flow cell, the precursor mixture formed from the mixed aqueous salt precursor and the aqueous acid precursor may react with the sample. Both the sample and the reacted aqueous solution may be subjected to a variety of real-time tests, such electrochemical tests and in line characterization techniques. These embodiments allow for the concentrations of the aqueous salt precursor and the aqueous acid precursor to be accurately and precisely maintained while allowing for increased safety when handling and testing the various toxic aqueous gas streams produced.
