Rootcrops processing waste management by Pyrolysis conversion
Journal Title: Annals of Tropical Research - Year 2020, Vol 42, Issue 2
Abstract
Processing the wastes from cassava was found to be the most suitable for pyrolysis conversion from among the rootcrops considered. Results showed that, of the four (4) cassava waste forms, larger briquette was found to have the highest vinegar yield conversion at 1.842L per kg while the shred form had the lowest at 1.203L per kg. The rate of vinegar production was also fastest from the briquettes at 2.388L per h and lowest from the raw form at 1.544L per h. Better vinegar yields were therefore associated with solid fuel forms, smaller bed porosity, smaller surface reaction area, and lower gasification temperature. Other factors that also affected vinegar production were the loading rates, air supply conditions, and heat exchanger efficiency. In this study, the available Logarithmic Mean Temperature Difference (LMTD) was only 45.67°C, indicative of poor performance of the exchanger unit. The heat exchanger unit’s design can be improved in future experiments by using good thermal conducting materials, reconfiguration, and increasing the conductor interface area. This should result in higher vinegar yields.
