Carbon monoxide at 25°c and steam at 150°c are fed to a continuous water-gas shift reactor. the product gas, which contains 50.0 mole% h2, 40.0% , and the balance emerges at 500°c at a rate of 2.50m3/h and goes to a condenser. the gas and liquid streams leaving the condenser are in equilibrium at 15°c and 1 bar. the liquid may be taken to be pure w"a) calculate the % excess steam fed to the reactor and rate of condensation of the water (kg/h) leaving the condensor. b) calculate the rate (kw) at which heat must be removed from the condensor. c) calculate the rate of heat transfer (kw) to or from the reactor (state which it is).

The final answer for the solution is Q= -8.8171* kW

Explanation:

basic:

100 moles of product gas

= 40 moles

= 40 moles

= 20 moles

for 40 moles of we need 40 moles of CO and 40 moles of

therefore,

Inlet :

No of moles of CO = 40

No of moles of = 40

but is in the outlet stream = 20 modes

Excess = %

= 50%

50% excess stream is fed to the reactor

a) Rate of conversion:

ρ_water (density ) =

Given volume rate = 3.5

3.5 * density = 3.5 *

b) Rate (kW)

ΔH = ΔH_1 + ΔH_2 +ΔH_3

Rate of condensation Q° =n° ΔH

Q = n° (ΔH_1 + ΔH_2 +ΔH_3)

ΔH_1 is sensible heat

V =

C_p(T) = a + bT + CT^2 +dT^3

H_2O

a=32.218

b=o.192 * 10^-2

c= 1.055 * 10^-5

d= -3.593 * 10^-9

ΔH_2 = ∫(a+bT +a^2 +dT^3)dT (of limits 100 to 500 )

= -13497.6

ΔH_3 =∫(a +bT +T^2 +dT^3)dT (of limit 95 to 100)

= -2751.331

phase change

ΔH_2 =  - ΔH_v

ΔH_v = 7.3  @ 100° C

liquid → vapor ⇒ ΔH_v

vapor → liquid ⇒ -ΔH_v

Q= n°(-16324.231)

=350 * (-16324.231)

= (-16324.231) *

= (-16324.231) * \frac{J}{mol}[/tex]

=  (-16324.231)  *kW

Q= -8.8171* kW

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
