A hydrogen stream at 293K and under atmospheric pressure has a dew point of 285K. It is to be further humidified by adding saturated steam at 220kN/m2 through a nozzle at the rate of 2kg steam to 30kg of hydrogen feed. Given that the gas outlet pressure after the mixing process is latm, determine: j) humidity of the hydrogen stream, ii) bumidity of the resultant stream, and iii) temperature of the resultant stream Specific heat of hydrogen-14.6kWkgĶ Specific heat of...

(30 points) We are designing a geothermal flash steam power plant that pumps water from underground geothermal reservoirs at 180 °C at 5 MPa to a tank at 150 °C. Some of the water flashes to produce saturated steam that is sent to a turbine and a water stream that is returned to the well. The output of the turbine is at 0.1 MPA. Assume that the system is well insulated. Determine: a. The flowrate of steam leaving the flash...

Your boss would like to connect a high temperature and pressure stream of steam (from another unit at the plant site) to a turbine that will be operated adiabatically and will serve as an energy source for a small electric generator. The steam is at T1 = 600 C and P1 = 10 bar. The outlet conditions of the turbine must be T2 = 400 C and P2 = 1 bar. The inlet diameter to the pipe connecting to the...

For this problem, you are separating ethanol (more volatile) from water in three flash separators. The feed solution contains 100 mol/s with 30% ethanol by mole.The first flash unit is operated at 87 °F. The mole fractions of ethanol in the vapor phase and liquid phase are 0.42 and 0.09, respectively. The vapor stream leaving the first flash is then fed to a 2nd flash and the temperature is decreased to 83 °F.The mole fractions of the ethanol in the...

A continuous sterilizer with a steam injector and a flash cooler will be employed to sterilize growth medium continuously with a flow rate of 2 m/hr. The time for heating and cooling is negligible with this type of sterilizer. The typical bacterial count of the medium is 5X10m, the desired probability of failure is 0.001. The bacterial spores in the medium can be characterized by an Arrhemus coefficient (a) of 4.707x10" hr and an activation energy (Ed) of 2.834x10 J/mol....

Chemical Engineering Question
100 KW of energy from a stream of superheated steam@ 200kg/sec, 10 bar and 2100 C is used in a heat exchanger to preheat a reactor feed. Determine the (a) enthalpy, (b) temperature and the phase of the resulting stream. 100 Kg/hr. of a saturated steam at 1 bar is mixed with superheated steam available at 4000C and 1 bar to produce superheated steam at 3000C and 1 bar. Calculate amount of superheated steam produced at 3000C...

3-40 In the condenser of a steam power plant the steam from the turbine enters the condenser at 0.10 bar with a quality of 95 percent and leaves at the same pressure as a saturated liquid. The steam is condensed by transferring heat to a stream of cooling water which enters at 1.3 bars and 5°C and leaves the heat exchanger at 1.2 bars and 25°C·The environmental temperature is 5°C. Determine a. the change in stream availability (exergy) of the...

9.2 A process instrumentation diagram for a flash drum is shown in Fig. E9.2. Steam is condensed in a steam coil to vaporize a portion of the liquid feed, and the liquid product s removed by a pump. There are ive control valves for the steam flow, vapor product, liquid product, feed flow, and steam chest (which allows the steam chest to be rapidly evacuated in emergency situations). Determine whether the five valves should be air-to-open (AO) or air-to-close (AC)...

A stream of air at 650.0 °C and 835 torr with a dew point of
50.0 °C flowing at a rate of 1915 L/s is to be cooled in a spray
cooler.
A fine mist of liquid water at 15.0 °C is sprayed into the hot air
at a rate of 110.0 g/s and evaporates completely.
The cooled air emerges at 1 atm.
For the flow diagram below, use two material balances and three
constraints to determine all unknowns except...
