Findings obtained from literature include:\u003c\/p\u003e\n\n\n\t\u003cp\u003eGlycol-water mixtures can be potentially accumulated in dry gas transmission pipelines. Operation conditions of the dehydration unit should be optimized to control the amount and corrosiveness of glycol-water being carried over into transmission lines.\u003cbr\u003e\n\tThe glycol-water hold-up in dry gas transmission pipelines contain high glycol content, i.e., \u0026gt; 95%. The accumulated glycol-water requires removal by direct drain from liquid traps, or by pigging either with methanol or water.\u003cbr\u003e\n\tFor transmission pipelines transporting natural gas containing CO2, the most likely corrosion mechanism associated with glycol-water mixtures is general corrosion. The corrosion rate has been proven to be low, i.e., much lower than 0.1mm\/year.\u003cbr\u003e\n\tFor sour gas transmission pipelines, although general corrosion has been ruled out as a major concern, localized corrosion and HIC can occur in glycol-water mixtures. The rate of localized corrosion and HIC remains undefined.\u003c\/p\u003e\n\n\n\u003cp\u003eThe list of recommendations to minimize the amount of glycol-water mixtures being carried over to dry gas transmission lines and to reduce the corrosion risks is developed. More research is required to study the potential corrosion mechanisms, i.e., pitting and HIC, of pipeline steels in glycol-water mixtures with high glycol content (\u0026gt; 95%) under sour gas conditions.\u003c\/p\u003e","brand":"PRCI Store","offers":[{"title":"Default Title","offer_id":44367630336078,"sku":"14822","price":500.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/prci-store.myshopify.com\/products\/pr-261-123602-r01-evaluation-of-the-corrosiveness-of-glycol-water-mixtures-in-dry-gas-transmission-lines-1","provider":"PRCI Store","version":"1.0","type":"link"}
