Jacketed Reactor Vessel

Description

Jacketed Reactor Vessel is a specialized piece of laboratory or industrial equipment designed for carrying out chemical reactions under precisely controlled temperature conditions. It consists of an inner vessel surrounded by an outer jacket or shell through which a heating or cooling fluid—such as water, oil, or a refrigerant—can be circulated. This setup allows for efficient heat transfer, enabling reactions to be heated, cooled, or maintained at stable temperatures ranging from as low as -90°C to over 200°C, depending on the materials and system.

Fluid Circulation: A chiller, heater, or circulator pump moves the heat transfer fluid through the jacket, indirectly influencing the temperature inside the vessel without direct contact with the reactants.

Temperature Regulation: For exothermic reactions, cooling fluid absorbs excess energy; for endothermic ones, a heating medium supplies it. This prevents runaway reactions and ensures consistent yields.

Insulation and Efficiency: The jacket acts as a barrier, reducing energy loss and allowing uniform heating/cooling across the vessel’s surface.

Applications of Preparation Vessel

Advantages of Jacketed Reactor Vessel

Precision: Superior temperature uniformity compared to heating mantles or oil baths, reducing hot spots.

Safety: Indirect heating/cooling minimizes risks like spills or explosions; explosion-proof options available.

Versatility: Customizable for vacuum operation, high-pressure reactions, or light-sensitive processes.

Scalability: Easy to swap vessels for different volumes, accelerating R&D workflows.

Key Features of Jacketed Reactor Vessel

Inner Vessel: Typically made from high-borosilicate glass for chemical resistance, visibility, and thermal shock tolerance. In larger or industrial setups, stainless steel or other metals may be used.

Outer Jacket: Forms a double-walled structure. Single-jacketed designs circulate fluid directly around the vessel, while double-jacketed versions include an additional insulating vacuum layer to minimize heat loss and prevent condensation at low temperatures.

Ports and Fittings: Includes inlets/outlets for fluid circulation, stirring mechanisms, temperature probes, and connections for gases, condensers, or sampling.

Sizes: Range from small lab-scale (100 mL to 5 L) to pilot or production-scale.

FAQ for Jacketed Reactor Vessel

What is a Jacketed Reactor Vessel?

A Jacketed Reactor Vessel (also known as a Jacketed Reaction Vessel or Double-Walled Reactor) is a specialized equipment used for chemical reactions requiring precise temperature control. It features an inner vessel for reactants surrounded by an outer jacket through which heating or cooling fluids (water, oil, steam, or coolant) circulate, enabling efficient heat transfer without direct contact with the product.

How does a Jacketed Reactor Vessel work?

The vessel works by circulating a heat transfer fluid through the jacket (or limpet coil) to heat or cool the inner contents. An agitator ensures uniform mixing. This setup provides excellent temperature regulation for exothermic or endothermic reactions, supports vacuum or pressure operations, and maintains process stability.

What are the key features of the Jacketed Reactor Vessel?

Fabricated from SS 304, SS 316, Mild Steel, or rubber-lined materials.
Double jacket or limpet coil design for uniform heating/cooling.
Variable speed agitators with VFD, custom nozzles, and dish ends.
Insulation, sensors, PLC/HMI options, and smooth surfaces for easy cleaning.
Capacities from 10 liters (lab scale) to 20,000 liters or higher.

What temperature range can a Jacketed Reactor Vessel handle?

Jacketed Reactor Vessels can typically handle a wide temperature range from as low as -90°C to -120°C (with appropriate coolants) up to over 200°C, depending on the heat transfer fluid and materials used. This makes them suitable for diverse reaction conditions.

Which industries use Jacketed Reactor Vessels?

They are widely used in the Pharmaceutical, Chemical, Cosmetic, Ayurvedic, Herbal, Nutraceutical, and Food Processing industries for chemical synthesis, formulation development, mixing, and controlled reactions in R&D, pilot plants, and commercial manufacturing.
