Distilling or rectifying plant

Pre-assembled process module unit of an ethane cracker unit, containing:  -quench water circulation loops, which contain a heat exchanger and circulation pumps to cool and recirculate quench water, -a water purification system, which removes hydrocarbon contaminants from quench water which is then re-used for dilution steam production (outside the module), -a pyrolysis oil purification system, which separates pyrolysis gasoline, heavy oil and coke fractions from the hydrocarbon contaminants that have been removed from the quench water, -an ethane feedstock start-up vaporizer and superheater, which vaporizes and heats ethane feedstock before sending the ethane to the cracking furnaces (outside the module), -a propane feedstock preparation system, which filters, vaporizes and superheats propane feedstock, before sending the propane to cracking furnaces (outside the module), and  -a chemical grade propylene preparation system, which filters and dries chemical grade propylene before sending it to the deethanizer (outside the module)
