Analysis of rectification plant for ethanol distillation

U sklopu završnog rada bilo je potrebno analizirati potrošnju toplinske energije za kontinuiranu rektifikaciju etanola iz smjese etanol-voda. Provedena analiza temeljila se na promjeni refluksa, masenog udjela etanola u džibri i masenog udjela etanola u konačnom proizvodu, te je odabran optimalni slučaj. Za taj slučaj proveden je termodinamički proračun i proračun čvrstoće kotlića. Za potrebe grijanja na raspolaganju je suhozasićena para tlaka 6 bara, a za hlađenje na raspolaganju stoji dovoljna količina rashladne vode.Task of this study was to analyse heat consumption of rectification plant for continuous ethanol production from ethanol-water mixture. This analyse was based on variation of the reflux, mass fraction of ethanol in distillate and in bottoms. The optimal case was chosen. Study contains thermodynamic and strength calculation of the boiler for optimal case. Saturated vapour with pressure of 6 bar is available for usage as a heat source. Enough cooling water is accessible for cooling
