at a rate of 0.102 Ib mol/s (see Example 4-2). This rate is equivalent to approx-
imate1:y 200 million pounds of ethylene glycol per year.
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
Profit = value of products - cost of reactants
$$$$
- operating costs - separation costs
