In a palm oil processing plant, the crude oil is heated using hot water from a furnace. The furnace burns oil palm biomass to heat water (initial water temperature of 18*'C). After the hot water was used to heat the crude palm oil, the hot water (cp = 4180 J/kg. °C) was then discharged to the drain at a rate of 7 kg/min at a temperature of 70°c. The funace has an efficiency of 82% and operates for 9 hours a day, 6 days a week, and 48 weeks in a year. The cost for 1 tonne of oil palm biomass is RM 18 (1 tonne = 105,500 kJ). Hence, the mill engineer intends to install heat exchangers to save on operating costs. This heat exchanger will use the hot water discharged into the drain earlier to pre-heat the new water before entering the furnace as shown in Figure 4. However, only 75% of the heat from the previously discharged water can be used. Determine: a) Heat transfer rate for heat exchangers c) The total annual cost that can be saved by using heat exchangers.
With regard to the flash vessel, consider 10 bar steam (hg=2,782 kJ/kg) entering a turbine and leaving as condensate (i.e. a saturated liquid) also at 10bar (hf=782 kJ/kg). If the mass flow rate of the above condensate were 10 kg/s and it entered a flash vessel at 1.5 bar how much saturated steam (hg=2,717 kJ/kg) and saturated liquid (hf= 536 kJ/kg) could it produce?
What is the THERMAL efficiency of each process? A completely insulated mixing vessel is designed to deliver water at 60 ⁰Cand atmospheric pressure at a rate of 4 kg/s by mixing two streams of incoming water in an environment at 25 ⁰C. Saturated steam at atmospheric pressure is inserted on the hot side. Two options are being considered for the cold side: (a) chilled water from the plant at 3 ⁰C or (b) water from the tap at 20 ⁰C (both at atmospheric pressure).
