säiliöreactor

A säiliöreactor, which translates to "tank reactor" in English, is a type of chemical reactor characterized by its cylindrical or prismatic shape. It is typically a closed vessel designed to contain a chemical reaction. The term is often used to describe a batch or continuous stirred-tank reactor (CSTR), where contents are mixed to ensure uniform temperature and concentration.

Säiliöreactors are versatile and can be employed for various chemical processes, including synthesis, polymerization, and fermentation. They are commonly used in industries such as petrochemicals, pharmaceuticals, and food processing. The design can vary significantly based on the specific application, including materials of construction, heating/cooling systems, and agitation mechanisms.

Key features of a säiliöreactor include its sealed nature, which allows for precise control over reaction conditions like pressure and temperature. The presence of an agitator, often a propeller or turbine, is crucial for efficient mixing, promoting heat transfer and preventing localized reactant depletion.

While säiliöreactors offer good control and flexibility, they can have limitations. For some highly exothermic reactions, heat removal can be a challenge, potentially leading to runaway reactions. The efficiency of mixing can also decrease with increasing viscosity of the reaction mixture. Despite these considerations, the säiliöreactor remains a fundamental and widely utilized piece of equipment in chemical engineering.
