Selection of Working Fluid for Organic Rankine Cycle by Energy and Exergy, For Low Temperature Low Enthalpy Dholera Geothermal Reservoir
Abstract: In today’s scenario of increasing energy demand, it is high time to give emphasis on renewable energy sources. The conventional energy sources that humanity is depending upon today are not only depleting, but also cause significant environmental impact. The burning of coal and fossil fuels causes serious air pollution and several major cities are already under deep threat due to the increasing amount of pollution. Future predictions show an exponential …

Synthesis and Immobilization of N-doped Titanium Dioxide for Degradation of Amaranth Dye under Visible Light Irradiation from Light Emitting Diodes
Abstract: Titanium dioxide photocatalysis has a great potential as green and sustainable technology to treat pollutants present in water. In the present study, N-TiO2 (nitrogen doped titanium dioxide)photocatalyst was prepared by wet method using titanium tetra iso-propoxide and NH3. The calcination of the prepared photocatalyst was performed at different temperatures. The prepared catalyst was characterized by DRS, FE SEM and TEM. The N-TiO2 was immobilized on the surface of the quartz …

Waste Minimization in Cumene Production Process
Abstract: This study deals with waste minimization in cumene production process using WAR (Waste Reduction Algorithm). Initially cumene production process is designed using ASPEN PLUS V8.8 chemical process simulator. Using WAR algorithm PEI’s (Potential Environmental Impacts) are calculated. Based on the PEI values process modifications are suggested to minimize the PEI’s. The modified process is eco-friendly by reducing the waste by 29.9%.

Formation, Analysis and Characterization of Wood Pyrolysed Oil
Abstract: Pyrolysis of wood is the possible path for converting biomass to higher valuable products such as bio-oil, bio-char and bio-gas. Bio-oil or liquid bio-fuels have higher heating values, so it can store and transport more conveniently the by-products bio-char and bio-gas, which can be used to provide heat required in the process. This work is focused on the formation, analysis and characterization of bio-oil which was obtained from the mixed …

Process Plant Simulations Using MATLAB
Abstract: This paper explains the systematic procedure to perform steady state process simulations of process plants using MATLAB. This procedure is illustrated with ethylacetate production process. Sequential modular approach is used to solve the material and enthalpy balance calculations in the flowsheet. Phase equilibrium behaviour plots and sensitivity analysis plots are drawn using MATLAB. Results obtained are compared with the ASPEN PLUS V8.8 simulation results.
