“…The environmental analysis of these designed systems is given in Table 10. 14,23,24,33,51 The factors given in Table 10 show that SSS-PCM-ETC is environmentally more stable among the studied units. SSS-PCM-ETC can mitigate 18.50 tons of CO 2 /year which is 51.64%, 65.18%, and 101.08% higher than those of SSS-PCM, SSS-ETC, and SSS, respectively.…”

“…While running at the ideal flow rate of 50 mL/min, their findings revealed a distillate production rate of 2.8 kg/day and a thermal efficiency of 33.80%. 24 The temperature of the entering water has a significant impact on the efficiency of a solar still. When the intake water temperature rises, the rate of water evaporation within the solar still accelerates.…”

This study investigates the individual and cumulative effects of phase change material (PCM) and evacuated tube collector (ETC) on the performance of a stepped solar still (SSS). Experiments have been performed on SSS, SSS loaded with PCM (SSS‐PCM), SSS coupled with ETC (SSS‐ETC), and SSS loaded with PCM and coupled with ETC (SSS‐PCM‐ETC). An innovative way of loading paraffin wax as PCM is introduced to utilize solar energy efficiently for the distillation process during off‐sunshine hours. ETC is used to provide pre‐heated RO wastewater to the distillation unit. The distillate output was observed maximum for SSS‐PCM‐ETC (4.97 kg/m2 day) which is 99% more than that of the SSS unit. The PCM and ETC individually with SSS unit increases the distillate output by 31% and 24%, respectively. The working time of the distillation unit was observed to be increased by 3 h by the use of PCM. The total heat transfer coefficient was evaluated at the maximum for SSS‐PCM‐ETC and was observed in the range of 16.94–167.04 W/m2 °C. The thermal energy efficiencies of SSS, SSS‐ETC, SSS‐PCM, and SSS‐PCM‐ETC were evaluated as 28.65%, 35.59%, 43.88%, and 44.04%, respectively. SSS‐PCM‐ETC is found to be the most economic with the best environmental conservation having maximum values of daily productive cost ($0.69) and carbon credits earned ($184.8).

The present study accentuate the noteworthiness of ongoing research in evolving sustainable sugarcane juice evaporation technologies to help the non‐centrifugal sugar (NCS) industry. Concentrated sugarcane juice (CSJ) is the raw material for the production of variety of value added products. A stepped solar still (SSS) could be one of the inexpensive solutions to evaporate water from sugarcane juice. In this study, a SSS having internal and external reflectors (SSS‐IR‐ER) is tested at 25 mL/min of sugarcane juice for obtaining CSJ. The thermo‐enviro‐economic performance of SSS‐IR‐ER unit is compared with SSS and SSS‐IR (SSS having internal reflectors) units. The final brix content (oB) of the CSJ obtained from SSS‐IR‐ER is found to be maximum (20.7 oB) which is respectively, 16.90% and 7.25% higher than those of SSS and SSS‐IR units. The total distillate output (condensate) and heat transfer coefficients show similar trends as that of brix values, which proves thermal dominance of SSS‐IR‐ER unit. For SSS‐IR‐ER, the convective and evaporative heat transfer coefficients were found to be maximum as 3.89 and 73.78 W/m2°C, respectively. The average values of energy and exergy efficiencies for SSS‐IR‐ER were, respectively, evaluated as 55.25% and 2.7% which were also observed maximum among the tested units. SSS‐IR‐ER also found to command in environmental and economic aspects with maximum values of total productive cost ($0.218), CO2 mitigation (14.93 tonnes) and carbon credit earned ($186.73). It is inferred that SSS‐IR‐ER is more economical and thermally efficient than SSS and SSS‐IR units.
