In terms of industrial production of soap:
Kettle
A kettle is a large, open, steel tank. The kettles used for saponification can hold up to 130,000 kg of material.
Boiled
The reaction mixture is kept boiling through the injection of high temperature, high pressure steam. This also acts to keep the reaction mixture well-stirred. Some soap from previous reactions is usually left in the kettle to help the water and oil mix by forming an emulsion (see emulsification later in this module).
Batch Process
A batch process is a reaction where everything is added at the beginning, the reaction proceeds until it reaches completion and then the products are removed. (This is in contrast with a semi-batch reaction where more reactants are added as the reaction proceeds, or a continuous process where reactants are added and products removed constantly throughout the reaction.) In this case, the fats and oils, caustic soda (sodium hydroxide), salt and water are added at the beginning of the reaction.
shouldnt this be called the kettle batch boiled process ?
