pany has decided that instead of flaring the associated natural gas separated along with test runs, three 5. An oil com crude oil, recover the lost heat by using the waste-heat recovery system. For pilot designs are offered; each has a lifetime of 5 years. The costs associated with each design are as follows: Capital Investment(S) Operating cost per 103 scf of natural gas (S) Annual Return of Investment Design 1 Design 2 Design 3 1,200,000 900,000 650,000 1.6 15% 1.3 2.1 15% 15% Determine that each design is preferred for what volume range of annual gas produced.
