Reflux - Wikipedia

Laboratory reflux apparatus for heating a chemical reaction A mixture of reactants and solvent is placed in a suitable vessel, such as a round bottom flask. This vessel is connected to a water-cooled Liebig or Vigreux condenser, which is typically open to the atmosphere at the top.

How to set up a reflux apparatus

the lab beforehand. • Be careful with concentrated sulfuric acid. It is highly corrosive. • Make sure that all the tubings are securely attached to the condenser. • Use hose clips in case the water leaks. • Do not plug the heating mantle directing into the wall outlet. • Do not touch the heating mantle once the reaction has started.

Part 16 - Welcome to Reactor Lab! - Reactor Lab

Adiabatic reactors are less expensive to build than reactors with heat transfer. However, when equilibrium conversion is a limitation then your ability to achieve high conversion with an adiabatic reactor is limited. A solution is to have a series of two or more continuous adiabatic reactors with heat exchangers between them.

Modelling a Process - A Tank Heating System

The heat added to the system, Qin, is a function of the overall heat transfer coefficient, U (W/m 2 K), the area available for heat transfer, A (m 2), the driving force for heat transfer which is the difference between the jacket temperature and the reactor temperature. Qin is given by: Rearranging the above equation, we get:

Jacketed Reactor Heating & Cooling - Sigma Thermal

Jacketed Reactor Heating & Cooling. In reactors, heating and cooling jackets are used to remove heat from exothermic reactions or provide the needed heat required to produce the desired endothermic reactions. Steam jackets that operate at high pressures can pose safety issues, especially when hazardous chemicals are being used within the reactor.

A lab funnel is just like any other funnel except that it was designed to be used in a laboratory setting. They can be made of plastic or glass and can have either a short stem or a long stem, depending on what they are needed for. There are several sizes that can be chosen from based on the amount of liquid that needs to go through them quickly.

Nuclear reactor - Coolant system | Britannica

Nuclear reactor - Nuclear reactor - Coolant system: The function of a power reactor installation is to extract as much heat of nuclear fission as possible and convert it to useful power, generally electricity. The coolant system plays a pivotal role in performing this function. A coolant fluid enters the core at low temperature and exits at a higher temperature after collecting the fission energy.

Most applications of COD determine the amount of organic pollutants found in surface water (e.g. lakes and rivers) or wastewater, making COD a useful measure of water quality.

Heat Exchanger - Nuclear Power

The classic example of a heat exchanger is found in an internal combustion engine in which an engine coolant flows through radiator coils and air flows past the coils, which cools the coolant and heats the incoming air. In power engineering, common applications of heat exchangers include steam generators, fan coolers, cooling water heat exchangers, and condensers.
