Economic potential EP is generally evaluated in stages. The first stage EP_I/O is EP_I/O = {product value} + {By-products value} - {Raw material costs} - {Auxiliary material costs} - {Ecological costs} Processing costs = {Equipment costs/Payback time} + {Cost of utilities} + {Additional environmental costs} The economic potential at any stage n is then EP_n = EP_I/O - {Processing costs} For the acetaldehyde production process the EP can be determined as: EP = EP I/O-{Rxtor costs/payback time} - {cost of sepns} - {utilities costs} - {additional environ costs} You can assume that environmental costs are 4-5% of product and by-product sales. It can be assumed also that sales/(all other costs in EP//o) ratio is 1.5 - 2.8. Use this information to determine annual EP_I/O after obtaining the safes costs of products and by-products [assume 340 days or 8000 hour of manufacture per year]. Use sales cost data you compiled earlier for year 2015. Economic potential EP is generally evaluated in stages.
