Heat exchangers, condensers Integrating processes

Aluminum plate-hn heat exchangers are often used as condensers in distillation and separation processes, but they require nonfouling and noncorrosive fluids. In the chemical industry, stainless steel or welded-plate heat exchangers have been used as top condensers of distillation columns, because they can be either directly installed inside the column or closely integrated outside (Figure 39),... 

Step 3. The open-loop instability of the reactor acts somewhat like a constraint, since closed-loop control of reactor temperature is required. By design, the exothermic reactor heat is removed via cooling water in the reactor and product condenser. We choose to control reactor temperature with reactor cooling water flow because of its direct effect. There are no process-to-process heat exchangers and no heat integration in this process. Disturbances can then be rejected to the plant utility system via cooling water or steam.
