The main reaction is CzHe+ H20 C3H5OH Under the reaction conditions, ethanol can form diethyl ether (di-ether) as shown below side reaction, which has 16% selectivity. The overall ethylene conversion is 20%. 2CH=CH-CH20O+ H2O The process scheme is shown in Figure 1. Fresh ethylene contains 0.2% ethane. It will mix with the recycled ethylene before fed to the Reactor which is at 585K and 80 atm. Steam is another reactant. The mole flowrate ratio of ethylene feed and steam is about 1:1 to enter reactor. Using chilled water, the stream from the reactor will be condensed to 20C before entering a Phase Separator. The vapour stream from the phase separator contains mainly ethylene. About 95% of the vapour will be recycled to the reactor and the rest will join the liquid to a Flasher operating at 3 atm and 10 C. The vapour from the flasher will be sent to an Absorber to absorb the heavy organics. The vent from the absorber will be used as fuel gas. About 20% of the ethanol/water mixture from the Ethanol Column will be used as the solvent for this absorber. Absorber would be more efficient at lower temperature. The liquid streams from the flasher and the absorber contain mainly ethanol, water and di- ether. It will be separated in a Crude Column first to remove 95% (recovery) of water from the bottom which contains less than 0.01 molex ethanol. The distillate from the crude column will be further purified to remove most of di-ether in the Ethanol Column where the bottom contains less than 0.001 mole diethyl ether and the top contains less than 0.1 mole% ethanol. You may need high reflux ratio and trays for this column. The bottom ethanol stream still contains water due to existence of azeotrope. It can be further separated in a Drying System by other methods such as extractive distillation, adsorption or membrane to get dry ethanol ethylene Reactor steam Phase Separator Di-ether Fuel gas Ethanol column Flasher Dry ethanol Absorber Crude column Waste water Drying system Figure 1.
