Ethanol is feed to continuous reactor with presence of Sulphuric Acid catalyzer to produce ethylene. Distillation process then will be applied to separate ethylene-HO mixture. Ethylene as a top product is then condensate with condenser to perform liquid ethylene. Hydrogenation of ethylene applies in another reactor with presence of Nickel catalyzer to produce ethane as a final product. Develop BFD for these processes.
