It is necessary to establish in the installed equipment, operating conditions and quality specifications in the purification of furfural produced in Cuba. To do this some literature review and experiments are carried out. The approved batches by the quality control are quantified as well as the heat and evaporation losses and the impact on workers health. Energy management is performed by identifying electricity as the energy source of higher consumption. Some measures are applied like coating the evaporator portions that are required together with condenser modification and improvement of the room ventilation. As a result it was shown that it is possible to purify the Cuban furfural in the installed equipment, the process efficiency increases in 5,5 %, the evaporation losses decrease and non-acceptance by quality control drops. If the imported furfural is replaced by the Cuban are saved about 39 000 • per year production.
