Problem 4 (15 points) An expansion stabilization plant built in 2021 (CEPCl 589) consists of two reciprocating pumps, each 200kW, and four horizontal stabilizing vessels, each 500m3. The new plant is designed to process 150 barrel/day of oil ( $60/ barrel). The only utility cost is power required to run the pumps. calculate the cost of manufacturing of the plant. Assume: - 96\% stream factor - No waste - $0.06/kWh - Lang factor of 3.63 - CEPCI (2001): 394 - An hourly labor rate of $28.64,3 shifts/day, 49 working weeks/year, and 5 working shift per week per operator
