Journal ArticleDOI
The application of membrane reactor technology in hydrogen production using S–I thermochemical process: A roadmap
TL;DR: In this paper, a hydrogen-permselective membrane reactor is proposed to improve the efficiency of the overall cycle and make hydrogen production more economical, which can be applied in highly corrosive environment like HI under a high temperature of about 500°C.
Journal ArticleDOI
Optimized design of a reverse osmosis system with a recycle
TL;DR: A mathematical model has been developed based on the input parameters of feed salinity, basic membrane characteristics, feed temperature, desired product quality and quantity to predict the operating recycle ratio at constant operating parameters as mentioned in this paper.
Journal ArticleDOI
Parametric Studies on Radiation Grafting of Polymeric Sorbents for Recovery of Heavy Metals from Seawater
TL;DR: In this article, the radiation induced graft polymerization technique was adopted to prepare metal chelate embedded polymers in sheet form in order to investigate the recovery the heavy metals from seawater, using different nonwoven substrate materials.
Journal ArticleDOI
Study of effect of high pressures and elevated temperatures on Bunsen reaction of Iodine–Sulfur thermo-chemical process
TL;DR: In this article, a detailed parametric study of the Bunsen reaction has been carried out through semi-batch experiments in a metallic tubular Bunsen reactor at different pressure and temperature with pure sulfur dioxide (SO 2 ).
Journal ArticleDOI
An engineering scale study on radiation grafting of polymeric adsorbents for recovery of heavy metal ions from seawater
TL;DR: In this article, a scheme was designed and developed for investigation of the recovery of heavy metal ions such as uranium and vanadium from seawater, and the grafted polyacrylonitrile chains were chemically modified to convert acrylatitrile group into an amidoxime group, a chelating group responsible for heavy metal uptake from seawaters/brine.
