ACCUMULATION OF FREE WATER IN GAS SUPPLY SYSTEMS WITH LIQUEFIED GAS WITH INCREASED BUTANE CONTENT

The presence of free water adversely affects the operation gas supply systems, causing corrosion elements, formation vapor locks in pipelines, ice and hydrate at low temperatures, especially when using liquefied hydrocarbon gases with a high content butanes. quantitative characteristics systems based on underground tanks butane are determined main provisions thermodynamic equilibrium liquid phases reservoir, conditions for ensuring minimum overpressure phase natural regasification product, supplying required amount to consumer all domestic needs during cold season. In result, accumulated moisture storage mode is determined. level filling number refills per year substantiated, while providing various utility depending climatic zone supplied facilities. It proven, content, taking into account accumulation annual cycle operation, it recommended use volume 5.0 m3 or more household needs, 1.0 only purpose food preparation.
