  • System and method for determining acid-gas (CO.sub.2, H.sub.2 S) loadings in an alkanolamine system
    Patent number: 5994147
    Abstract: A method for determining the concentration of acid-gases in an amine-regeneration system, such as is typically found in a natural gas refining plant, having a device for measuring the pH of the system from which the concentration of the acid-gases complexed and the amine can be calculated using an empirically-derived relationship between acid-gas concentration and pH. The invention also includes a system for controlling amine regeneration based upon the above described determining method.
