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

Techniques of Waste Heat Recovery Waste heat recovery is being more used more and more often today as it is becoming more effective‚ due to increasing energy prices‚ technological developments and a decrease in equipment costs. Heat recovery can be classified into three main strategies: recycling energy back into the process‚ recovering the energy for other onsite use and using it to generate electricity in combined heat and power systems. Once the system has been made as efficient as possible before
