Compared to other petroleum, the natural gas combustion remains cleanest and one showing less CO2 emission. These reasons make of important issues study. The separation NGL is energy intensive. This operation performed through a series column including debutanizer column. present work devoted optimize consumption at level response surface technique deploying central composite numerical design f...

building pounding occurs between two adjacent buildings with small gap or without sufficient separation distance. it leads to damage buildings during earthquake due to impact. many researchers have investigated building pounding based on impact force reduction and energy dissipation increase, when two buildings collide with each other. in numerical investigations, using specific link element, i...

The conversion and storage of solar energy into a fuel holds promise to provide a significant part of the future renewable energy demand of our societies. Solar energy technologies today generate heat or electricity, while the large majority of our energy is used in the form of fuels. Direct conversion of solar energy to a fuel would satisfy our needs for storable energy on a large scale. Solar...
