Tank blanketing

Tank blanketing, also known as inert gas blanketing or nitrogen blanketing, is a process used to create an inert atmosphere in storage tanks that contain volatile liquids or chemicals. The primary purpose of tank blanketing is to prevent the formation of explosive mixtures with air, reduce product evaporation, and minimize contamination. In tank blanketing, an inert gas (commonly nitrogen or sometimes carbon dioxide) is introduced into the space above the liquid in the tank.
