By heat exchange, the butane fed into the reactor is brought to the reaction tempera- ture of 1000K It is desired to maintain an isothermal reactor How much heat must be added or removed per g mole of butadiene formed? Assume the pressurė is 100 kPa. What are some reasons why the heat load may be different from the value you calculate?

The Neches Butane Products Co. makes butadiene, C,Hg, by separating butenes.
C,Hg. from refinery gases piped to them, and then further dehydrogenating the
butenes to butadiene. In order to increase capacity they would like to be able to dehy-
drogenate butane, C,H10, in one step without the intermediate separation of the
butene. The C,H, formed would be separated, and any unreacted C,H,, or C,Hg
would be recycled to the reactor. One of the large engineering companies claims to
have such a process. You have just been employed by Neches B.P. Co.-fresh from
school-and are requested to make some calculations on the proposed process:
C,H,0(1) → C,H,(g) + 2H,(g)
By heat exchange, the butane fed into the reactor is brought to the reaction tempera-
ture of 1000K It is desired to maintain an isothermal reactor How much heat must
be added or removed per g mole of butadiene formed? Assume the pressure is l00
kPa. What are some reasons why the hecat load may be different from the value you
calculate?
