Components

The glass-lined reactor is designed with integrated top head and vessel body instead of removable large cover. Manway is included for interior inspection and maintenance. The glass-lined reactor typically consists of glass-lined vessel body, jacket, agitator, agitator drive with motor and gearbox, mechanical seal, manway, inlet and outlet nozzles, temperature measurement system and bottom discharge valve. Baffles, dip pipes, thermowells, and other internal components can be equipped depending on the process.

How does a glass-lined reactor (close-type) work?

The glass-lined reactor is structurally enclosed with top nozzle for material feed, and allows the materials to undergo continuous mixing, mass transfer, and reaction with the working agitator. At the same time, the heating or cooling medium circulates through the jacket for rising/decreasing/constant temperature control, allowing for stable process under set temperature, pressure and time conditions.

After the reaction processes, the materials are discharged from bottom nozzle and sent to downstream processes such as filtration, crystallization, distillation, or storage. The integrated structure reduces the number of large body flanges and sealing joints and is more suitable for large-capacity chemical processes requiring reliable sealing and long-term stable operation.

Open-type glass lined reactors consist of a few important parts: the vessel body, a removable cover, sealing gaskets, and clamps. Sealing gaskets are necessary to form a seal between the cover and the body, while the clamps hold them firmly together, so the reactor stays tightly closed and safe during operation.

The internal design pressure depends on the sealing method. With a packing seal, the vessel is rated for 0.2 MPa. With a mechanical seal, the design pressure can be 0.4 MPa or up to 1.0 MPa, depending on the configuration.

Some glass lined reactor models are equipped with quick-opening manhole covers and dual manholes, to enable easier access for inspection and maintenance. The lid is designed with butt-welded flanges to ensure stronger connections and simplify the installation of extra components, combining durability with practical convenience.

When working with liquid heating or cooling media, the half-pipe coil jacket generally provides better heat transfer performance. Its effective area is smaller, about one-third less than that of a conventional jacket, but the flow rate is two to three times higher. In half-pipe coil jackets, the faster flow helps avoid many of the problems seen in conventional designs, like uneven heat transfer or buildup inside the jacket. This way, the heat spreads more evenly, making the process both more efficient and steadier during operation.

The half-pipe coil jacket is recommended. Cooling water often contains ions such as H⁺ and Cl⁻ that can accelerate corrosion. In conventional jackets, deposits can accumulate and worsen this effect. The faster flow in half-pipe coil jackets minimizes deposits and reduces the risk of wall corrosion.
