Sensible heating of the charge accounts for only part of the energy required by a distillation system.
An approximate heat-up calculation can be useful for comparison when its boundary is explicit. Equipment sizing requires a validated complete duty and operating basis.
Mass × heat capacity × temperature rise describes warming on a stated basis. Vaporization, vessel heating, heat losses and auxiliary operations add requirements. In the handbook example, 334,720 kJ over one hour corresponds to about 93 kW before those additions; neither number sizes the complete installation.

Atomic Idea
Sensible heating of the charge accounts for only part of the energy required by a distillation system.
Reasoning
Mass × heat capacity × temperature rise describes warming on a stated basis. Vaporization, vessel heating, heat losses and auxiliary operations add requirements. In the handbook example, 334,720 kJ over one hour corresponds to about 93 kW before those additions; neither number sizes the complete installation.
Boundary
An approximate heat-up calculation can be useful for comparison when its boundary is explicit. Equipment sizing requires a validated complete duty and operating basis.
