The profit from a chemical plant will be the difference between income from sales and the cost to produce the chemicals. An approximate formula might be 

For an ethane feed of 400 million pounds per year and a production rate of 200 million pounds of ethylene glycol per year. The profit is shown in Table 5-4. 

You will learn more economics of chemical proces.sing in your senior design class. 

Using 58 million a year as a rough estimate of the profit, you can now make different approximations about the conversion, separations, recycle streams, and operating costs to learn how they affect the profit. 

Profit = Value of products - Cost of reactants - Operating cost - Separation costs
