process design problem
Problem: To utilize an excess of approximately 75 x 10 kg/yr of ethylene the Gulf Coast plant is producing by manufacturing ethyl alcohol. The sales department indicates 150,000 m/yr of 190 percent ethyl alcohol can be sold. Design Team Assignment: Investigate the design of a plant to convert substantial part of the excess ethylene to 150,000 m /yr of 190 proof ethanol (85.44 mole % ethyl alcohol and 14.56 mole % water). Ethylene Feed: 96 mole % ethylene 3 mole propylene 1 mole % methane Assume 100% Conversion Ethylene (CHA) + Water (H20) - Ethanol (CHO) Main Reaction: 2 Ethanol (CHO) - Diethyl Ether (C:H).0) Propylene (CH) + Water (HO) - Isopropanol (CHO) Methane (CH) - Coking Crotonaldehyde (C.H.O) (Waste) Feed Composition: 4:1 Water to Ethylene ratio for complete conversion 1. Maximum Potential Profit - The manufacturer price of the ethylene feed is $ 0,18/1b. Given the information provided below, calculate maximum profit range per year (Not including equipment and operating costs). 2. Draw schematic of overall boundary (showing input and outputs) of the ethyl alcohol process. Develop a box flow diagram, including reactor, mixing and splitting points, separators, purge and recycle streams. Develop a process flow diagram, including condensers, heaters, distillation columns, reactors, etc. Additional Information Species Water (W) Ethyl Alchohol (EA) Ethylene (EL) Diethyl Ether (DEE) Methane (M) Propylene (PL) Isopropanol (IPA) Crotonaldehyde (CA) MW 18.02 46,07 28.05 16.04 42.08 60.10 70.09 74.12 0.705 Sp.
