Write a material balance based on the information below:

A new facility to produce Monoethanolamine $($MEA$)$ 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 of Monoethanolamine $($MEA$)($at $99\mathrm{.}5\%$ purity$).$ The plant is to be located in

Richards Bay, South Africa.

The following feed streams are available:

Ammonia feed is available at $10$ atm and $50$C from an adjacent plant. Ammonia is

available as an aqueous solution of $55$ wt$.\%$ of ammonia and $45$ wt$.\%$ water.

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

Reaction temperature of $150$ oC 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.
