Products are removed from the reactor after the reaction has proceeded to completion.īatch processes are suitable for small-scale production (less than 1,000,000 lb/yr) and for processes where several different products or grades are to be produced in the same equipment (Douglas, 1988). Additional reagents may be added as the reaction proceeds, and changes in temperature may also be made. The compositions change with time, but there is no flow through the process. In a batch reactor, the reagents are added together and allowed to react for a given amount of time. It is important to ensure that the equipment specified will be capable of achieving the desired yields and selectivity. Reactor design is a vital step in the overall design of a process. The center of any chemical process is the reactor, where chemical reactions are carried out to transform feeds into products. 6 Safety Considerations in Reactor Design.5 Heating and Cooling of Reacting Systems.4.3.2.2 Challenges in Microorganism Design.4.3.2.1.3 Operation Conditions, Equipment, and Scale Up.4.3.2.1.2 Product Isolation and Purification.4.3.2.1.1 Cost, Yield, and Productivity.4.3.2 Microorganism Design and Selection.2.6 Step 6: Estimate Reactor Performance.2.5 Step 5: Preliminary Sizing, Layout, and Costing of Reactor.2.4 Step 4: Determine Rate-Limiting Step and Critical Sizing Parameters.2.3 Step 3: Determine Materials of Construction.2.1.4 Heat and Mass Transfer Properties.2.1.3 Reaction Mechanisms, Rate Equations, and Rate Constants.2.1.2 Equilibrium Constant and Gibbs Free Energy.1.1.3 Continuously Stirred Tank Reactor (CSTR).
