His company produces 1,000 tons per year of

ethane, sold at 0.20 R$/kg. His group was tasked with evaluating the economic viability of the Sabic process for his plant as a way to update its products and increase the margin in sales. Your job is to determine the optimal project economically, producing any projects that will maximize the net present value of the project. The available ethane can be consumed in whole or in part and any proportion of ethylene or acetic acid that will be produced by the catalyst can be made. Based on previous experiences, you know that you will have to defend any decision made in the project and the best defense is the economic justification.

Sales believes that it will be able to sell ethylene for 0.50 R$/kg. But they are not sure because it is a new product for their company, they also believe that they can sell acetic acid for 0.40 R$/kg. It may be a good idea to test the sensitivity of the optimal plant design and the savings for uncertainties in the selling price of both products. The plant design should be as environmentally friendly as possible. Recycling and recycling of materials must be done with maximum economic potential. Energy use should be minimized to a justifiable economic limit. The plant design must be controllable and safe to operate.
