Once-through reboiler arrangement Here reboiler liquid is withdrawn from the bottom downcomer or from a chimney tray located above the bottom sump. Typical arrangements are shown in Fig. 4.7. [Pg.95]

A single stage is allowed for a once-through reboiler, a kettle reboiler, or when the bottoms draw compartment is separated by a preferential baffle from the reboiler compartment (Sec. 4.5). Half or zero theoretical stages are allowed for an unbaffled recirculating reboiler arrangement. [Pg.422]

Kettle reboilers have five connections, two on the tube side and three on the shell side. Steam or hot oil flows through the tube side and provides the heat source. Flow rate is carefully controlled and frequently linked to the bottom temperature control system. The higher the flow rate, the hotter the bottom product. The shell side has three nozzles one liquid-product feed line, one vapor-return line to the column, and one heavy-liquid-out product line. A kettle reboiler can be used to (1) control the liquid level on the bottom of the column, (2) control the temperature of the column, and (3) help control product purity in the bottom of the column. Figure 6-5 shows what a kettle reboiler looks like, and Figure 6-6 shows two thermosyphon and one kettle reboiler arrangements on a distillation column. [Pg.144]
