Nowadays, energy extraction from sea waves as a renewable energy source has been increasingly considered. In addition, the growing demand for energy as a result of development of industrial activities, air pollution caused by the use of fossil fuels and greenhouse problems caused a new challenge for humankind. Tidal energy is a type of energy that is derived from converting the tidal power of t...

attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
