Equipment Name: Reactor

The document describes a reactor (J-5) that receives NaOH and produces a MSG solution and filtrate. Mass and energy balances are provided. The MSG solution enters a fixed bed reactor (J-6) that produces clear MSG solution and waste material. Another mass and energy balance is shown for J-6.
