Introduction of Solar Drying Technology to Trinidad and Tobago
A review of the existing solids management practices in Trinidad and Tobago and experience elsewhere defined the future needs and identified solar drying as a preferred technology for the subject project. Upon analysis of the local conditions, it was calculated that approximately 19 MJ/m2 (1886 kWh/m2) of solar radiation, at 30°C annual average temperature and 80% relative humidity level is appropriate at the project site and that these parameters are adequate for the solar dryer application. The estimated 7,450 m2 cell area for drying associated with average electrical power consumption of 18 to 20 kWh/tonne of water extracted will provide an evaporation rate of 2.2 kg water/m2.day. The solids are expected to be dried from approximately 16-18% dry solids to 70-90% dry solids.
