Sodium bicarbonate is manufactured industrially through the operation of a _______________ tower?
Show answer Hide answer
Answer: B. Baffle
Explanation
Sodium bicarbonate is manufactured industrially through the operation of a specialized baffle tower system. Baffle towers provide internal obstacles that promote effective gas-liquid contacting during carbonation reactions. This design prevents clogging issues that often plague packed columns when solid precipitates form during reaction. The Solvay process and related carbonation methods produce sodium bicarbonate via gas-liquid chemical reactions. Baffle towers utilize cascading liquid trays or baffles to enhance interfacial surface area for mass transfer. Controlling temperature and reactant concentration inside the tower ensures high product purity and crystal yield.
Soda ash and sodium bicarbonate manufacturing plants utilize large-scale carbonation towers for continuous production. Efficient gas-liquid contact in baffle towers maximizes carbon dioxide conversion efficiency in chemical synthesis. Proper equipment selection prevents operational downtime caused by salt scaling and crystal deposition on internals. Option A is incorrect because standard plate columns can easily plug with precipitated solids during industrial carbonation. Option C is incorrect because packed columns are prone to severe fouling and plugging from solid sodium bicarbonate. Option D is incorrect because the process explicitly requires baffle towers rather than leaving the equipment unspecified.
