An industry is proposing to construct a new coal-fired power plant that produces 2300 MW electricity with efficiency of 39%. Coal has a heating value of 10,750 Btu/lb, and contains a sulfur content of 2.4%. It is expected that 95% of sulfur will be converted to SO2. The New Source Performance Standards (NSPS) limits the SO2 emission rate from any coal-fired power plants to 1.2 lb/ 106 Btu heat input. a) Determine coal consumption in lb/ hr b) Determine SO2...

You are assigned to help an aged 30% efficient 800-MW coal-fired power plant in Indonesia. You learnt that a warning has been issued to this power plant demanding that the rate of SO2 emission from this power plan has to be reduced to no more than 0.6 kg s. You find out that every million BTU of heat supplying into this aged plant emits 0.8 lb of SO2. Since this power plant is aged, its power generation can be easily...

a shell and tube heat exchanger is required to heat brine for a
food processing plant. Hot waste water from another part of the
plant is available at 90°C and a flow rate of 0.7kg/s to perform
the heating duty. An existing heat exchanger is available that has
twoshell passesand 4 tube passes. Each tube pass has a total length
of 20m and the tubes are found to be thin walled copper with a
nominal diameter of 25mm.

A coal-fired power plant is burning bituminous coal that has an energy content of 12,000 Btu/lb. The power plant is burning the coal at a rate of 110 lb/s. The efficiency of the powerplant is 33%, which means that 67% of the total energy from the coal is lost as waste heat. a. A new heat exchanger is installed that is capable of using 0.12% of the waste heat to heat an air stream for use in another process in...

Apple Inc.: Capital Budgeting Analysis Apple Inc. (ticker: AAPL) is considering installing a new and highly sophisticated computer system in one of its manufacturing facilities, which would cost $71.0 million. Delivery and installation would add another $1.2 million to the initial cost. The new computer system has a 5-year class life under MACRS. Because of the half-year convention, it will take six years for Apple to fully depreciate the cost of the system (MACRS percentages: 20, 32, 19, 12, 11...
