Since the presence of such acidic compounds in sour gas cause corrosiveness, it is necessary to ensure that they are removed before natural gas enters the pipelines.<\/p>\n<p>This process is usually done by using aqueous solutions of alkanolamines such as monoethanolamine (MEA), diethanolamine (DEA) and methyl diethanolamine (MDEA) as a scrubber solution by removing the acidic compounds of hydrogen sulfide and Carbon dioxide is produced from natural gas to sweeten sour gas. The gases adsorbed on the amine are separated from the amine solution so that the amine solution can be reused.<\/p>\n<p>Anionic interferences (such as chloride, nitrate, etc.) as well as by-products of amine degradation (such as organic acids) by forming thermally stable salts (HSS) with amine cause inactivation and limit the ability of amines.\u00a0and prevent them from reviving.<\/p>\n<p>Therefore, measuring the amount of anions and organic acids in these solutions regularly is of particular importance. In order to reduce this problem during sour gas treatment, the amount of HSS should reach its minimum value and not exceed 10% of the total amine concentration.<\/p>\n<h3>Methods for measuring amines and anions<\/h3>\n<p>There are different analysis methods to determine the quality of amines. The proposed methods include measuring pH, concentration of amines, suspended particles, liquid hydrocarbons, chloride, iron, HSS and the amount of acid gas. Metrohm ion chromatography is used as a suitable method to measure the amount of amines and also to determine the amount of inorganic anions and organic acids in the amine solution.<br \/>Table 1 shows the test conditions for measuring amines, cations, anions and organic acids.<\/p>\n<p><a href=\"http:\/\/yaghootweb.artinazma.net\/wp-content\/uploads\/2024\/01\/pic1-e1635143499637.png\"><img fetchpriority=\"high\" decoding=\"async\" src=\"http:\/\/yaghootweb.artinazma.net\/wp-content\/uploads\/2024\/01\/pic1-e1635143499637.png\" alt=\"Test conditions for measuring amines, cations, anions and organic acids\" width=\"707\" height=\"393\" \/><\/a><\/p>\n<div id=\"attachment_5190\" style=\"width: 501px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" aria-describedby=\"caption-attachment-5190\" src=\"http:\/\/yaghootweb.artinazma.net\/wp-content\/uploads\/2024\/01\/\u0646\u0645\u0648\u0646\u0647-\u0627\u0633\u062a\u0627\u0646\u062f\u0627\u0631\u062f-\u0622\u0646\u06cc\u0648\u0646-\u0647\u0627-\u0648-\u06a9\u0627\u062a\u06cc\u0648\u0646-\u0647\u0627-\u0628\u0627-\u0622\u0634\u06a9\u0627\u0631\u0633\u0627\u0632-\u0647\u062f\u0627\u06cc\u062a-\u0633\u0646\u062c\u06cc-IC-\u0645\u062a\u0631\u0627\u0647\u0645-\u0633\u0648\u0626\u06cc\u0633-e1635143636760.png\" alt=\"Separation of standard sample of anions and cations with Swiss metrohm IC conductometric detector\" width=\"491\" height=\"267\" \/><p id=\"caption-attachment-5190\" class=\"wp-caption-text\">Figure 1 \u2013 Separation of a standard sample of anions and cations with a Swiss Metrohm IC conductometric detector<\/p><\/div>\n<h2>Application of Metrohm ion chromatography in cooling samples:<\/h2>\n<p>It is possible to measure anions in water and cooling samples after dialysis for ten minutes using the dialysis unit.
