Physicochemical properties of the commercially procured rubber seed oil (RSO) were studied to evaluate its potential as viable feedstock for biodiesel production. The procured rubber seed oil were characterized for acid value, saponification value, free fatty acid, flash point, kinematic viscosity, and refractive indices using standard methods. Results indicate that the procured rubber seed oil...

Over 85% of all new heat exchanger applications in oil refining, chemical, petro-chemical, and power generation are accommodated through the use of conventional shell and tube type heat exchangers. The fundamental basis for this statistic is shell and tube technology is a cost effective, proven solution for a wide variety of heat transfer requirements. However, there are limitations associated ...

Of late, the automobiles of all categories are massively increasing which aggravates dependency on fossil fuel thus, accessibility petro-fuel decreases relentlessly. Under these circumstances, investigations taking new dimensions to find alternative, renewable with cost-effective exclusively biofuels. However, a newer approach has been attempted for production biodiesel from wild stuff Spirulin...

While the United States owns only three percent (3%) of the total world petro-oil reserves, it uses over twenty-five percent (25%) of its total global output on an annual basis. Furthermore, the US petro-oil consumption is expected to double by 2050. While the sources for US oil are innumerable, many of the countries which contribute vastly to the US oil supply are economically and politically ...
