Jacketed glass reactor is one of the important types of glass reactors. It is a compartment designed to control the temperature of its material, using a cooling or heating “shell” around the reactor through which a refrigerant or heating fluid circulates.

How does a jacketed reactor work?
A cooling liquid flows through the jacket, collecting heat energy from the outer surface of the reactor vessel and carrying it away as the cooling liquid exits at the jacket outlet. When the flow of cooling liquid through the jacket increases, more heat is removed.
How does a glass reactor work?
A reactor works by allowing the chemicals into a contained space and agitating them via the centrally mounted agitator. The vessel will typically have baffles included to ensure the sufficient level of turbulence inside to mix / blend the chemicals and enable the reactor.
How do jacketed vessels work?
In chemical engineering, a jacketed vessel is a container that is designed for controlling temperature of its contents, by using a cooling or heating “jacket” around the vessel through which a cooling or heating fluid is circulated.
How does a double jacket work?
In a double jacket system, a chiller is used to circulate fluid through the inner jacket, while the outer jacket is used for vacuum insulation to ensure the vessel will maintain the desired temperature.
How are reactors heated?
BWRs heat water and produce steam directly inside the reactor vessel. Water is pumped up through the reactor core and heated by fission. Pipes then feed the steam directly to a turbine to produce electricity. The unused steam is then condensed back to water and reused in the heating process.
How do you calculate the area of a reactor jacket?
- =(1.022+0.1311)*D*D*D.
- 0.2 =1.153*D*D*D.
- so now i got the value of D=0.5576 m=0.56 m, L=0.728 m=0.73 m,
- = (2*Pi*r) * (L)
- = (2*3.147*(0.56/2)) * (0.73)
- = 1.2864 Sq.m= 1.29 Sq.m.
- And now we got the Heat transfer Area of Cylinder, and we still need to calculate the Heat transfer surface of the Torispherical Dish,
Why glass lined reactors are used?
Glass Lined reactors are primarily used for carrying out critical chemical processes where corrosion resistance and chemical inertness are of critical importance. Steel reactors, whilst very important in the industry, have many drawbacks compared to the glass lined options.
Why glass lined reactors are blue in Colour?
The blue coloring comes from the cobalt that was added to the glass formulations a long time ago. Usually the choice of which color to use comes down to concerns about cleaning and what particles could be left behind.
Which type of glass used in glass lined reactor?
Borosilicate Glass 3.3
GLASS REACTOR
Our range of reactors and components, manufactured from Borosilicate Glass 3.3, provide excellent resistance to chemical attack and corrosion as well as transparency for optimum visual observation.
Why do jackets work?
Coats keep us warm because of the material of the coat. Our body supplies the heat, and the material helps to trap body heat and keeps the heat from escaping into the air.
What do you mean by jacketed?
Jacketedadjective. wearing, or furnished with, a jacket.
What is the function of jacket in agitated vessel?
For highly corrosive or highly reactive materials, a jacket has the advantage that there are no extra materials of construction and no extra metal surface in contact with the process other than the normal vessel wall. There is also less risk of cooling fluid coming into contact with the reaction mass.
How does a dimple jacket work?
Dimple jackets utilize a thin gauge stain- less steel layer that is plug welded to the vessel shell in a regular pattern. The punched and spot welded areas are called dimples, which create turbulence of the heating or cooling fluid flowing through the jacket.
What is a jacketed heat exchanger?
This heat exchanger mimics those used in the process industry. It can show heat transfer by using the outer skin (or ‘jacket’) of the vessel, or by a coil inside the vessel. You can set a continuous feed to the vessel for heating or you set a fixed batch for heating.
What is jacket piping?
Jacketed piping is a double-walled pipe. The special devices are used to control the distance between two pipes – spacers, guide plates, partition/end plate and spiders. Spacers support the core pipe from jacket pipe and to ensure uniform gap between core and jacket pipes.
How hot is it inside a nuclear reactor?
In a nuclear fusion reactor, the hot, charged gas known as plasma reaches out of this world temperatures at 150 million degrees Celsius, or 10 times hotter than the center of the sun.
How hot is the water in a nuclear reactor?
Water enters through the bottom of the reactor’s core at about 548 K (275 °C; 527 °F) and is heated as it flows upwards through the reactor core to a temperature of about 588 K (315 °C; 599 °F).
Which reactor produces only heat?
Explanation: Burner reactor is a type of reactor using U235 as fuel.
How do you calculate the capacity of a reactor?
Popular Answers (1)
- Space velocity = flow rate of the reactants/ the reactor volume.
- GHSV =Hourly volumetric feed gas flow rate/reaction volume.
- LHSV= Hourly volumetric feed liquid flow rate/reaction volume.
- WHSV=Hourly mass feed flow rate/ Catalyst mass.
How do you find the heat load of a reactor?
Heat load on condenser = M x ƛ = 2000 x 0.9 x 100 = 180000 KCal, But condenser will also cool the condensed liquid, so to compensate that consider 20% of total latent heat load = 180000 x 1.2 = 216000 KCal. Let the total mass be 500 L, Again sensible heat = 500 x 0.9 x 0.5 x (65 – 5) = 13500 Kcal.
