A new facility to produce monoethanolamine is being considered due to an increase in demand. Therefore, you have been requested to design a plant to produce $10000$metric tons per annum monoethanolamine$($at $99\mathrm{.}5\%$ purity$).$The following feed streams are available: $-$ammonia feed is available at $10$ atm and $50\backslash$deg C from an adjucent plant. ammonia is available as aqueous solution of $55$wt$\%$ of ammonia and $45$wt $\%$ water.

$-$Ethylene Oxide$(99\mathrm{.}99\%$ pure$)$ is available at $5$atm and $40\backslash$deg C

$-$Reaction temperature of $150\backslash$deg C is maintained in the reactor, and a pressure of $160$ atmosphere to avoid the evaporation of ammonia

$-$Under specified conditions of reaction, only MEA is produced when the feed ratio of ammonia$/$Ethylene oxide is $10$

$-$The plant should operate for $330$days in a year, in order to allow for shutdown and maintenance.
