Optimal feed flow sequence for multi-effect distillation system integrated with supercritical carbon dioxide Brayton cycle for seawater desalination

Selection of optimal feed flow sequence for a multiple effect evaporator system

A nonlinear model is developed for a SEFFFE system employed for concentrating weak black liquor in an Indian Kraft Paper Mill. The system incorporates different operating strategies such as condensate-, feed& productflashing and steam& feedsplitting. This model is capable of simulating a MEE system by accounting variations in τ, U, Qloss, physicothermal properties of the liquor, F and operating...

An Optimized System for Advanced Multi-Effect Distillation (AMED) Using Waste Heat from Closed Gas Brayton Cycles

This report presents a novel Advanced Multi-Effect Distillation (AMED) method that can enable the production of substantial quantities of low-cost desalinated water using waste heat from high temperature reactors (HTRs). Conventional MED systems can currently compete with reverse osmosis desalination in areas where energy costs are relatively low, such as the Middle East. Because AMED can perfo...

Sterilization of Microorganisms with Supercritical Carbon Dioxide

Thc sterilizing effect of supercritical carben dioxide (SC-CO,) is described as compared with gaseous C02(G-CO,) and liquid CO,(L-CO,). Baker's yeast, ltscherichia eoli, Staphylococcus aure us and eonidia'ofAspergiilus niger were sterilized by treating with SC-CO, at 200 atm and 350C when the water contcnt of each microorganism was 70 .90%, However, dry cells with a water content of 2 .1O% coul...

Building better plastics with supercritical carbon dioxide

Nanocomposite plastics are a promising class of materials with a range of applications, particularly in the automotive industry. By incorporating mineral material of nanoscale dimensions, the mechanical properties of the bulk plastic, such as strength, thermal stability, and flame retardance, are drastically improved, with little to no impact on other favorable properties such as low weight. In...
