What is a Batch Reactor? - Definition from Corrosionpedia

What is a Batch Reactor? - Definition from Corrosionpedia

A batch reactor is commonly used in steel, stainless steel, glass or exotic alloy production. The liquids or solids used in the batch reactor are usually charged with connections in the reactor's top covers. Any vapors and gases generated during the process are discharged from connections in the top cover.
