Forward Osmosis Desalination Using Thermoresponsive Ionic Liquids: Bench-Scale Demonstration and Cost Analysis

Industrial & Engineering Chemistry Research, Journal Year: 2025, Volume and Issue: unknown

Published: April 1, 2025

Forward osmosis (FO) desalination using thermoresponsive ionic liquid (IL)-water mixtures is a promising technology for treating nontraditional water sources. However, its demonstration has primarily been at the lab-scale, with flux and recovery values that are not representative of realistic applications. In this work, performance tetrabutyl-phosphonium trifluoroacetate (P4444TFA), as well new dual draw P4444TFA tetrabutyl-ammonium (N4444TFA) characterized. The combines higher osmolality one IL lower critical solution temperature (LCST) second to outperform constituents same total concentration in (70 wt %). Experiments were first performed lab-scale coupon tester understand effects osmotic pressure viscosity on through membrane. Bench-scale experiments then an element 1 m2 membrane area evaluate IL-based FO produced feed from oil gas. Specifically, 10 kg IL-water was used 3 real feed, resulting recoveries 60% initial final fluxes 14 LMH LMH, respectively. bench-scale experimental results inputs cost analysis, yielding levelized (LCOW) $1.18 per m3. This reveals potential solutions cost-effective challenging feedwaters FO.

Hybrid Mechanical Vapor Compression and Membrane Distillation System: Concept and Analysis

Membranes, Journal Year: 2025, Volume and Issue: 15(3), P. 69 - 69

Published: Feb. 28, 2025

The concept of integrating mechanical vapor compression (MVC) with direct contact membrane distillation (DCMD) is presented and analyzed. hybrid system utilizes the DCMD to harvest thermal energy MVC reject brine preheat a portion seawater intake simultaneously produce additional fresh water. Based on operating temperature, requires specific consumption between 9.6 24.3 kWh/m3, which equivalent 25 37% less than standalone MVC. Similarly, freshwater production can range 1.03 1.1 kg/h, 3% 10% increase relative when at temperatures 50 90 °C, respectively. However, this enhancement achieved expense an average 60% larger total surface area. This partially due incorporation area MD modules mostly reduced temperature differences. Altering permeate-to-feed ratio module led marginal change in overall without any power consumption. Increasing length by 50% resulted enlargement rate reduction A modified structure that additionally distillate heat sought. 5% water 45% rise over original obtained.
