Development of Geo-Polymer based Light Weight BricksBy Rajendra Prasad, Priya G. D. V, Nagamalleswara Rao Kanidarapu
Abstract: Light weight geopolymer bricks were developed during this study. The mix was made with lime sodium silicate and fly ash as ingredients. A maximum shrinkage was observed at CaO lime ratio of 1.0. Bulk densities were also lower at the ratio of 1.0. The maximum cold crushing strength (CCS) value was found at the ratio of 0.745. Increase in mix water decreased the strength. Water content of 24% is recommended …

Pinch analysis of Cumene process using Aspen Energy AnalyzerBy Nagamalleswara Rao Kanidarapu, G. Koteswara Reddy, P. Rajendra Prasad, V. Sujatha
Abstract: This article is divided into two parts. In the first part a process flow diagram for the production of cumene is designed with Aspen HYSYS. Cumene obtained is 98.78% pure and the designed plant is safe to environment with less emissions. In the second part heat exchanger networks (HEN) was developed for the process plant by performing pinch analysis using Aspen Energy Analyzer. Retrofit analysis was applied to find an …
