Weather effect and cost analysis of solar adsorption desalination system using MIL-101(cr) – Graphite oxide composite material

Abstract

Solar-powered adsorption desalination systems (ADSs) are a significant way to provide clean and fresh water using environmentally friendly adsorbent materials. This work presents an innovative investigation of solar-driven ADS's performance and cost analysis using a metal–organic framework MIL-101(cr) with and without a 2D graphite oxide (GO) material. The investigation is conducted over a complete year using lumped modeling by MATLAB and TRNSYS software. The production cost of desalinated water is evaluated using solar energy and waste heat sources. It is found that the effect of adding 2D-GO to MIL-101(cr) is positive on the isotherms and negative on the kinetics properties; hence the overall performance of MIL-101(cr) and MIL-101(cr) + GO was very close with an average difference of 2%. Optimum-specific daily water production and gain output ratio achieved at summer 24 m3/ton-day and 0.7, respectively, using MIL-101(cr). The cost is estimated to be 4.7 $/m3 using solar energy and 1.01 $/m3 using waste heat. The performance parameters indicate the effectiveness of MIL-101(cr) in solar/waste heat-driven ADS at a reasonable cost to remote areas.
