To actualize the project a total of 12 million US dollars of total investment is required and 3.5 % is working capital. And the plant attainment will be 80 % per annum. The following raw materials will be need i. 2300 tones of nitrogen gas per day at the cost $ 200 per ng ii. 4000 tones of Oxygen gas per day at the cost of $25 per Kg 3500 Kg of Vanadium catalyst per hr at the cost of $ 250 per Kghh 695 ii. 4567 m per hr of Cooling water at the cost of $ 20 per m /hr iv. V. 3567 MJ per day of electricity at cost $45 per MJ/day. Assuming that only 10 % and 1% of royalty will be considered, calculate the total operating cost for this plant. mu bmairten [7 marks] nou
