FORMATION OF GAS HYDRATES, METHODS OF COMBATING THEM AND CAPTURE OF METHANOL LOSSES IN THE GAS PHASE

Abstract

The article provides a brief analysis of the formation of gas hydrates, methods of combating them and the capture of methanol losses in the gas phase. Under certain thermodynamic conditions, natural gases combine with water to form hydrates, which accumulate in mining and main gas pipelines, increase hydraulic resistance, reduce pipeline capacity and, in some cases, fill the entire section of the pipeline. Hydrate compounds can form not only in gas pipelines, but also in gas wells, depending on the conditions. Therefore, during the extraction and transportation of natural gases, it is almost always possible to encounter hydrate compounds in mining equipment and gas pipelines. Because hydrates of natural gases are unstable compounds, they are separated into gas and water when the temperature rises or the pressure decreases. Hydrate compounds are a white crystalline mass that looks like ice or black. Components such as carbon dioxide, hydrogen sulfide, nitrogen, etc. are often found in natural gases. The presence of sour gases dramatically accelerates the process of hydration. Keywords: hydrates, methanol losses, gas phase, sour gases, hydraulic resistance, hydration formation
