Acetone, a valuable solvent, can be recovered from air by absorption in water or by adsorption on activated carbon. If absorption is used, the conditions for the streams entering and leaving are as listed below. If the absorber operates adiabatically, estimate the temperature of the exiting liquid phase using a simulation program.

Some concern has been expressed about the possible explosion hazard associated with the feed gas. The lower and upper flammability limits for acetone in air are $2\mathrm{.}5$ and $13$mol$\%,$ respectively. Is the mixture within the explosive range? If so$,$ what can be done to remedy the situation?
