(35 A chemical Problem (1) plant consists of the following equipment: 1. Stainless steel Shell and tube heat exchanger (U tube) has a heat transfer area equals 100 m and works under pressure 10 bar. 2- Carbon steel absorption tower of diameter 3 m, height 20 m, 40 sieve plates (the cost of 1 plate equals to 116 at 1979) and operating pressure is 6 bar. 3. Carbon steel horizontal separator of diameter 0.5 m, length 10 m and operating pressure is 25 bar. 4. Carbon steel propeller works by 30 Kw drivers. 5- Stainless steel centrifuge horizontal basket has a 200 cm diameter. 6- Carbon steel vacuum drum filter has a heat transfer area equals 20 m 7- Boiler work under pressure 1 MPa has a capacity of 9x104 kg/h 8- Belt conveyor has a width of 1 m and 100 cm length 9. Carbon steel absorption ceramic packed tower of diameter 3 m, height 20 m, the packing size equal 20 mm and operating pressure is 6 bar. 10-Other equipment have a total cost of $ 600000 The annual direct variable cost which consists of raw materials, utilities, miscellaneous materials, and shipping and packaging is L.E 1 x 10Operating labor = 200 men at L.E 15 per employeehou. Plant operates 300 days 24 hours per year. The general expenses (indirect cost) are L.E 5 x 109. The daily production is 10000 ton. Accordingly, estimate the following a) The fixed capital investment for the plant b) Calculate the manufacturing and production cost for the plant c) Suggest a suitable sell price for the products units so as to make this project profitable and mention reasons for your choice.
