Evaporator heat integration

The concept of the appropriate placement of distillation columns was developed in the preceding chapter. The principle also clearly applies to evaporators. The heat integration characteristics of distillation columns and evaporators are very similar. Thus evaporator placement should be not across the pinch. ... [Pg.356]

Table 22.1 presents the data for a process. An evaporation process is to be integrated with the process. The evaporator is required to evaporate 1.77 kg s-1 water. The latent heat of vaporization of the water can be assumed to be 2260 kJ-kg 1. For an assumed A Tmm = 10°C, suggest an outline evaporator configuration that will allow heat integration of the evaporator with the background process. [Pg.462]

The sketch below shows a distillation column that is heat-integrated with an evaporator. Draw a conirot concept diagram which accomplishes the following Directives (a) In the evaporator, temperature is controlled by steam, level by liquid product, and pressure by auxiliary cooling or vapor to the rcboiler. Level in the condensate receiver is controUed by condensate. [Pg.298]

Figure 5.9 presents the flowsheet prior to heat integration. Fresh and recycled phenol is evaporated and mixed with hydrogen in the evaporator (Ev-1) at about 2 bar. The gas mixture enters the catalytic hydrogenation reactor (R-l). The inlet temperature should be kept strictly constant, in this case at 150°C, to avoid the... [Pg.144]
