The combustion of n c3h8 = 100 kmol.h^{-1} propane gas (
pure fuel stream) takes place at isobaric-atmospheric conditions (
P= 1atm) in a continuous reactor, in the presence of air and using
an oxygen inlet of n O_{2}( g) = 1000kmol.h-1 according
to:

C_{3}H_{8} + 5O_{2}( g) -----
3CO_{2} + 4H_{2}O

The inlet gases are supplied at T=25^{o}C, and leave the
reactor at T= 300^{o}C, according to the following
values:

- Calculate the extent of reaction and fractional conversion of propane
- Calculate the High Heating Value HHV
_{C3H8}and specific heat of reaction R1 at 25^{o}c and 1atm - Calculate heat released or absorbed in the process ( MW)

If the reaction takes place in a tubular reactor, following a first order kinetics, according to

-r_{C3H8 ( g) =} K.
C_{c3H8( g)} k = 60hr^{-1}

Iv estimate the reactor volume needed
to carry out the reaction in previous conditions,
c_{3}H_{8} (g) = 0.5

A fuel gas consists of 75% butane (C4H10), 10% propane (C3H8)
and 15% butene (C4H8) by volume. It is to be fed to the combustion
chamber in 10% excess air at 25ºC, where it is completely burnt to
carbon dioxide and water. The flue gases produced are to be used to
generate 5 bar steam from water at 90ºC.
(a) Determine the maximum flame temperature.
(b) If 5% of the heat available for steam production is lost to
the atmosphere,...

A 16.0 gram sample of propane gas
(C3H8) is burned according to the equation
C3H8(g) + 5O2(g) →
3CO2(g) + 4H2O(g).
In an enclosed container with a volume of 2.25L at a
temperature of 322K.
If the sample of propane burns completely and no oxygen
remains in the container, calculate the mole fractions of
CO2 and H2O.
Calculate the total pressure in the container after the
reaction.
Calculate the partial pressure of CO2 and
H2O in the container after the...

Liquid Propane (C3H8(l)) enters a combustion chamber at 25
degrees C and 1 atm at a rate of 0.4 kg/min where it is mixed and
burned with 150% excess air that enters the combustion chamber at
25 degrees C. The heat transfer from the combustion process is 53
kW. Determine (c) the average specific heat at constant pressure of
the product gasses, and (d) the temperature of the products of
combustion.

In a combustion device, a mixture of 82 lbs of butane and 212
lbs propane C3H8 are burned with just enough air for complete
combustion. How many lbs of total combustion products are formed?
Round your answer to the nearest whole number

Calculate the theoretical A/F ratio for the complete combustion
of propane (C3H8) on mole basis and mass basis. Also, calculate the
equivalence ratio for the following reaction:
C3H8 + 7O2 + 26.32N2 → 3CO2 + 4H2O + 2O2 + 26.32N2

In a closed combustion vessel, propane (C3H8) and air are mixed
at equivalence ratio of 1.11, temperature of 298 K, and pressure of
1 bar. The mixture is burned to produce solely CO2, CO, H2O, and
N2. The heat rejected from the vessel is 820 MJ/kmol of fuel. What
are the final temperature and final pressure of the mixture? Since
neither O2 nor H2 is present in the burned gas, dissociation can be
neglected.

What is the mass of propane, C3H8, in a 50.0 L container of the
gas at STP?

Consider the combustion of propane gas, C3H8(g) + 5O2(g) 3CO2(g)

gas grills. Anyone who has every filled or moved those tanks knows
they can get pretty heavy. a) How many grams of propane are in 1
pounds of propane? Use the conversion 1 lb = 454 g. (Express your
