Technical details and manufacturing context for Heating/Cooling Jacket

Definition
A heating/cooling jacket is an essential part of a reactor module that provides precise temperature control by circulating heating or cooling fluids through an enclosed space surrounding the reactor vessel. It maintains optimal reaction conditions, prevents thermal runaway, and ensures consistent product quality in chemical processes.
Working Principle
The jacket operates by circulating a thermal fluid (such as water, oil, or steam) through the space between the reactor wall and the jacket shell. Heat transfer occurs through conduction across the reactor wall, with temperature controlled by adjusting fluid flow rate, temperature, or switching between heating and cooling circuits.
Common Materials
Stainless Steel 316L, Carbon Steel, Hastelloy
Technical Parameters
  • Jacket thickness and clearance between jacket and reactor wall (mm) Customizable
Components / BOM
  • Jacket Shell
    Forms the outer containment for thermal fluid circulation
    Material: Stainless Steel
  • Inlet/Outlet Nozzles
    Connections for thermal fluid entry and exit
    Material: Stainless Steel
  • Baffles
    Direct fluid flow for optimal heat transfer distribution
    Material: Stainless Steel
Engineering Reasoning
0.5-6.0 bar (gauge pressure), -20°C to 200°C (fluid temperature)
8.0 bar burst pressure for carbon steel jackets, 250°C thermal degradation temperature for EPDM gaskets
Design Rationale: Thermal fatigue from cyclic stress exceeding 207 MPa yield strength of 316L stainless steel at ΔT>150°C, causing crack propagation at stress concentrations
Risk Mitigation (FMEA)
Trigger Fluid velocity exceeding 3 m/s causing erosion-corrosion
Mode: Wall thickness reduction below 2.0 mm minimum design specification
Strategy: Installation of erosion-resistant Inconel 625 baffles at flow impingement points
Trigger Glycol concentration dropping below 40% v/v in heat transfer fluid
Mode: Ice crystal formation and expansion at -15°C causing jacket rupture
Strategy: Automated glycol concentration monitoring with 35% v/v low-level alarm and automatic makeup system
