How does a liquid tank work in the chemical industry?
A liquid tank in the chemical industry is used for storing, handling and in some cases mixing chemicals under controlled conditions. The design and materials of the tank are chosen based on the chemical properties, temperature and safe handling requirements of the liquid.
Tanks are often manufactured in stainless steel 304 or acid-proof 316/316L, depending on the need for corrosion resistance and application. The choice of material is important to ensure that the tank is suitable for the chemical process in question.
Processöverskott offers new and used tanks for the chemical industry in various volumes, from about 100 liters up to 250,000 liters. The tanks are available in several designs depending on the construction and previous use, and many are available for quick delivery.
Function and structure
Liquid tanks in the chemical industry are cylindrical, can be vertical or horizontal and are often equipped with conical or flat bottoms for drainage. They can be equipped with agitators for homogenization as well as inspection hatches, level gauges and valve connections. CIP systems can be used to simplify cleaning and reduce the risk of residues in tanks, pipes and valves.
Materials and construction
Tanks are often manufactured in stainless steel 304 or acid-proof 316/316L depending on the chemical properties and corrosion risk of the liquid. Stainless steel 304 is typically used for less aggressive media and water-based solutions, while acid-resistant 316/316L is a common choice for higher corrosion resistance requirements, such as chlorides, acids or salt content.
The construction is normally welded, and the surface finish can vary depending on the application and requirements. Common finishes include polished or satin finishes, adapted to the medium and the needs of the process.
Pressurized and atmospheric solutions
Liquid tanks can be atmospheric for simple storage or pressurized for processes where gas evolution or vacuum may occur. Pressurized tanks are equipped with safety valves, pressure gauges and, if necessary, vacuum protection to safely handle overpressure and underpressure.
