These are exactly the opposite conditions to those in a tubular flow reactor where there is virtually no mixing of the reactants and the products.
Figure 9 A line diagram illustrating a continuous stirred tank reactor. A steady state must be reached where the flow rate into the reactor equals the flow rate out, for otherwise the tank would empty or overflow.
The residence time is calculated by dividing the volume of the tank by the average volumetric flow rate. By kind permission of Total.
A CSTR reactor is used, for example in the production of the amide intermediate formed in the process to produce methyl 2-methylpropenoate. Sulfuric acid and 2-hydroxymethylpropanonitrile are fed into the tank at a temperature of K. The heat generated by the reaction is removed by cooling water fed through coils and the residence time is about 15 minutes.
A variation of the CSTR is the loop reactor which is relatively simple and cheap to construct Figure In the diagram only one loop is shown. However, the residence time in the reactor is adjusted by altering the length or number of the loops in the reactor.
Figure 11 A line diagram showing a loop reactor used in the production of poly ethene. Loop reactors are used, for example, in the manufacture of poly ethene and the manufacture of poly propene. Ethene or propene and the catalyst are mixed, under pressure, with a diluent, usually a hydrocarbon. A slurry is produced which is heated and circulated around the loops.
Particles of the polymer gather at the bottom of one of the loop legs and, with some hydrocarbon diluent, are continuously released from the system. The diluent evaporates, leaving the solid polymer, and is then cooled to reform a liquid and passed back into the loop system, thus recirculating the hydrocarbon. Most chemical reactions are faster at higher temperatures and heat exchangers are frequently used to provide the heat necessary to increase the temperature of the reaction.
A common heat exchanger is the shell and tube type Figures 12 and 13 where one part of the process flows through a tube and the other part around the shell. A good example where heat exchange is important is in the manufacture of sulfur trioxide from sulfur dioxide in the Contact Process where the excess heat is used to warm incoming gases.
The heat from the reaction is transferred to incoming gases across the tube wall Figure 12 and the rate of heat transfer is proportional to:. Figure 12 Illustrating a heat exchanger used in the manufacture of sulfur trioxide. Thus the rate of heat transfer required will determine the size of the exchanger but when a chemical reaction also occurs in the exchanger as in the case of tubular reactors , it is important to take into account the residence time of the materials whether they be gases or liquids in the heat exchanger.
Figure 13 This exchanger is used for cooling product with water which enters the shell side at 1 and leaves at 2. The product to be cooled flows through the small tubes. The exchanger has been taken out of service to clean the tubes to improve the efficiency of the cooling process. Another example of a heat exchanger is the condenser at the top of a distillation column. Here heat from the vapour emerging from the top of the column is removed by, for example, cooling water.
The vapour cools down and condenses and the temperature of the water increases. In the future many chemicals may be produced in reactors about the size of a large desktop computer, known as microreactors.
