$2-(50).$ In an ethylene glycol production plant, a packed bed reactor is used to produce $30\mathrm{.}000$ ton ethylene oxide per year by the following reaction.

$C_2{H}_2+\frac{1}{2}{O}_{2}longrightarrowC{H}_{2}longrightarrowC{H}_2$

$($A$)$

$($B$)$

$($C$)$

Ethylene and oxygen are fed in stoichiometric proportions to a packed bed reactor that is operated isothermally at $260C.$ This reaction is exothermic, and a cooling system is provided from a cooling tower to remove the excess energy of reaction. By considering the interruption of the cooling flow, perform a HAZOP analysis and fill the following Table. Rows of the table can be increased.
