Electromagnetic radiation Electromagnetic radiation (EM radiation or EMR) is one of the fundamental phenomena of electromagnetism‚ propagating and traveling through space via photon wave particles‚ carrying radiant energy. In a vacuum‚ it propagates at a characteristic speed‚ the speed of light‚ normally in straight lines. EMR is emitted and absorbed by charged particles. As an electromagnetic wave‚ it has both electric and magnetic field components‚ which oscillate in a fixed relationship to one

Multicomponent distillation 1) Mass balances The feed flowrate is 350 kmols hr-1 and the feed composition is known: 48 mol% propene‚ 50 mol% propane and 2 mol% butane. The distillate stream composition: 99.9 mol% propene and 0.1 mol% propane. The bottom product stream contains 0.5 mol% propene but the mole fractions of propane and butane are unknown. Therefore‚ mass balances are carried out around the distillate column. Overall mass balance: F=D+B Component mass balance for propene: xFF=yDD+xBB
