Cooling Coils/Jacket

A cooling coils/jacket is an integral heat exchange component of a neutralization reactor designed to remove excess heat generated during exothermic neutralization reactions. It maintains optimal reaction temperatures by circulating cooling fluids through coils or within a jacket surrounding the reactor vessel, ensuring process safety, product quality, and reaction efficiency. The component is available in configurations such as internal coils or external jackets, each tailored to the reactor's geometry and heat transfer requirements. Materials on file include stainless steel 316L, Hastelloy C-276, and titanium, selected based on corrosiveness of the process media. Key parameters include design pressure (1.0–1.6 MPa), design temperature (-40–200°C), heat transfer area (0.5–20 m²), tube diameter (25–76 mm per DIN 2448), wall thickness (2–6 mm per DIN 2448), surface roughness (0.4–1.6 μm Ra per ISO 4287), material grade (304/316L per ASTM A312), connection size (DN15–DN100 per DIN 2633), weight (50–500 kg), and test pressure (1.5×design). These values are directory reference ranges and must be confirmed for the specific model and application. The cooling coils/jacket is a component, not a standalone product, and its performance depends on integration with the reactor system. Buyers should verify all specifications with the legal manufacturer or supplier before procurement. The component is designed for use in chemical manufacturing, particularly in neutralization processes where exothermic reactions require precise temperature control. Proper selection and maintenance are critical to ensure safe and efficient operation.

Cooling fluid (typically water, glycol, or thermal oil) is circulated through coils immersed in the reactor contents or through an external jacket surrounding the reactor vessel. Heat from the exothermic neutralization reaction is transferred to the cooling fluid through conduction and convection, maintaining the reaction mixture within the desired temperature range. The flow rate and temperature of the cooling fluid are controlled to match the heat generation rate. The design of the coils or jacket, including tube diameter, wall thickness, and surface area, influences heat transfer efficiency. Regular monitoring of temperature and pressure ensures the system operates within design limits.
