Energy requirements and exergy inefficiencies for processing of malt drink were estimated for a Nigerian
brewery. The process was divided into twenty-one basic unit operations and grouped into four main
group operations: silo house, brew house, filter room and packaging house. The energy intensity for
processing a batch of 9.8 tonnes brew grains to 562 hl of malt drink was estimated as 261.63 MJ/hl
consisting of electrical (41.01%), thermal (58.81%) and manual (0.19%) of the total energy. The most
energy intensive group operation was the Packaging House operation, followed by the Brew House
operation with energy intensities of 223.19 and 35.94 MJ/hl, respectively. The exergy analysis revealed
that the packaging house operation was responsible for most of the inefficiency (92.16%) followed by
brew house operation (7.17%) and the silo house and filter room operations with less than 1% of the total
exergy lost. The most exergy loss took place in the pasteurizer, which accounted for 59.75% of the overall
system inefficiency. Modification in the pasteurizer and use of spent grains as alternate source of energy
in the steam boiler were recommended to improve the energy efficiency of the system
