Description

Technical Field

[0001] The utility model belongs to the technical field of fatty acid storage, in particular to a chemical product storage tank. Background Art

[0002] Fatty acids are a class of compounds composed of three elements: carbon, hydrogen, and oxygen. They are the main components of neutral fats, phospholipids, and glycolipids. Fatty acids can be divided into two categories: one is saturated fatty acids without carbon-carbon double bonds in the molecule, such as stearic acid, palmitic acid, etc.; the other is unsaturated fatty acids with one or several carbon-carbon double bonds in the molecule, the most common of which is oleic acid. Oleic acid has only one carbon-carbon double bond in its carbon chain, so it is also called monounsaturated fatty acid. After its production is completed, it needs to be stored in storage tanks. Chemical product storage tanks are equipment used to store various chemical raw materials, intermediates, and products.
