Reaction vessels can be categorized based on five key dimensions: material, heating/cooling method, operating pressure, agitation type, and structural design. Different types are suited to specific production scenarios.
Classification by Vessel Material
Carbon Steel Reaction Vessels: Suitable for environments free of corrosive liquids; commonly used in standard operations such as oil processing.
Stainless Steel Reaction Vessels: Offer excellent heat and pressure resistance; suitable for most applications in the petroleum, pharmaceutical, and scientific research sectors; capable of handling viscous and particulate materials.
Glass-Lined (Enamel) Reaction Vessels: Feature a glass coating for superior corrosion resistance; widely used in the chemical, food, and pesticide industries.
Steel-Lined Reaction Vessels: Include subtypes such as steel-lined PE and steel-lined PTFE; resistant to strong acids and alkalis; suitable for reactions involving highly corrosive media.
Classification by Heating/Cooling Method
Electric Heating Reaction Vessels: Feature simple construction and convenient temperature control; the most common type for laboratories and small-to-medium-scale production.
Steam Heating Reaction Vessels: Utilize boiler steam as the heat source; offer high heat transfer efficiency; suitable for large-scale continuous production processes.
Thermal Oil Circulation Heating Reaction Vessels: Capable of achieving high temperatures exceeding 300°C; suitable for synthesis reactions requiring high operating temperatures.
Far-Infrared Heating Reaction Vessels: Provide uniform heating without localized overheating; suitable for temperature-sensitive fine chemical reactions.
Jacketed/Coiled Cooling Reaction Vessels: Efficiently remove heat generated during the reaction; suitable for highly exothermic processes such as polymerization and nitration.
