Title (EN) METHOD FOR DETERMINING ACID-GAS (CO2, H2S) LOADINGS IN AN ALKANOLAMINE SYSTEM
(FR) PROCEDE PERMETTANT DE DETERMINER LES CHARGES DE GAZ ACIDES (CO2, H2S) DANS UN SYSTEME D'ALCANOLAMINE
Abstract:
(EN) Method and apparatus for determining the concentration of acid gases in an amine regeneration system of a natural gas processing plant having an alkanolamine contactor (20) for removing acid gases from a natural gas supply (12). Sensors (65, 115) for detecting pH in situ are provided and the pH is correlated to the acid gas loading in the rich amine stream (62) and the lean amine stream (89), respectively.
(FR) La présente invention concerne un procédé et un appareil permettant de déterminer la concentration de gaz acides dans un système de régénération d'amine d'une usine de traitement de gaz naturel, lequel appareil comprend un contacteur d'alcanolamine (20) destiné à enlever les gaz acides d'une quantité de gaz naturel (12). Des capteurs (65,115) permettent de détecter le pH in-situ et le pH est mis en corrélation avec la charge de gaz acide dans le flux d'amine à haute teneur (62) et dans le flux d'amine à faible teneur (89), respectivement.
