Distillation is one of the most important separation technology adopted in the chemical process
industries. All the petrochemicals units use at least one distillation column for the separation and
purification of the ...
Carbon emission from fossil fuel, estimated by IPCC has thrown considerable challenge for researchers and scientists in the past decade. For obvious reasons, the applications of clean technologies such as chemical looping ...
A number of studies have been carried out for the combustion of coal by different types of model
i.e. shrinking core model, shrinking reactive coal model, random pore model, etc. Some of them
are briefed as follows.
Everson ...
In the present process industries, there is a need to reduce gaseous pollutants of all kinds because of heightening environmental concerns. This increases requirements for clean fuels and less polluting combustion systems. ...
It has been estimated that fossil fuels will be fully exhausted by the end of this century.
Hence alternatives for them have been searched which includes mainly renewable
source of energy such as solar energy, geothermal ...
Light cycle oil (LCO), which is a product of the catalytic cracking of the vacuum gas oil in the FCCU, contains a good percentage of aromatics, monocyclic and polycyclic. These compounds need to be separated from the ...
In the present work, an explicit modelling of gas recovery from dissociation of gas hydrates
by thermal stimulation is done. The dissociation method taken is thermal dissociation. The
main objective of this research is ...
This work reports stability of oil in water macro-emulsions with diesel oil dispersed in a continuous water phase and stabilized either by anionic (Sodium Dodecyl Benzene Sulphonate (SDBS)) or nonionic (Polysorbate80 ...
The linear stability of two-layer plane Couette flow of Newtonian fluids past a soft, deformable neo-Hookean solid with wall slip is studied using a combination of low wavenumber asymptotic analysis and a numerical ...
Copper nanoparticles have drawn the attention of the scientific and the research community due to its excellent catalytic behaviour, electrical conductivity, surface enhanced Raman scattering activity and good compatibility. ...
In the present work the stabilization of water-in-oil emulsion prepared with water dispersed in a continuous diesel phase using two different non-ionic surfactants (Span 80 and Tween 80) has been studied. The emulsions ...
The effects of cross-buoyancy on the flow and heat transfer characteristics of a long semi-circular bar in a confined channel have been investigated. The numerical results have been presented and discussed for the ranges ...
In the T-junction, when two fluids mix at different temperatures, then generation of cyclical stresses takes place, and these stresses are responsible for the failure of pipe material because these stresses cause thermal ...
The study of combined free and forced (or mixed) convection around different geometrical bluff bodies in an enclosure has been a topic of considerable attention of researchers in recent times due to its fundamental and ...
Effects of wall confinements (β) and of Prandtl numbers (Pr) on the two-dimensional
laminar flow around a heated tapered trapezoidal bluff body are investigated numerically at low
Reynolds numbers (Re) for 0.71≤Pr≤100 ...
Drinking water containing high amount of fluoride and nitrate can cause serious health hazards
to the people across the globe. Fluoride concentrations between 0.5-1.5 mg/l are beneficial, for
the prevention of dental ...
The electrochemical oxidation is an effective treatment technology for wastewater treatment. In this method, use of the electrical energy can produce complete oxidation of pollutants on high oxidation potential. In present ...
Recent industrial advances has led to an increase in pollution be it air, water or any other kind of pollution. Industries like iron and steel plant, electroplating, coke industries discharge a good deal of phenol and ...
The removal of salicylic acid from waste water by catalytic wet air oxidation (CWAO)
process using perovskite type oxide LaFeO3 catalyst gives efficient results at the lower
temperatures of 140◦C. The conversion of ...
In the present work, hexavalent chromium removal from tannery wastewater was investigated using a low cost activated carbon, carbonized and prepared from corncobs. Corncob based activated carbon (CAC) was characterized to ...
