OPERATIONS INVOLVED IN THE PRODUCTION OF CAUSTIC SODA
Objective: Caustic soda, or sodium hydroxide, is used in the manufacture of
plastic wrap, soap and paper and is the major ingredient in most oven cleaners
and liquid drain cleaners. In chemical manufacturing, it is used in metal
processing, oil refining and water treatment. Caustic soda is used in the
refining of bauxite ore from which aluminium metal is extracted.

AIM : : Inspecting and finding overall view on caustic soda production plant
improving the efficiency of overall process by making slight improvements in
equipments.
PROBLEM IDENTIFICATIONS / METHODOLOGY : Once we visit the
industry we will identify the problems involved in the production and come
up with an adequate solution.

Abstract of Project:Sodium hydroxide, also known as caustic soda and lye, is
an inorganic compound with NaOH as caustic soda formula. It is a white-
colored solid ionic compound consisting of hydroxide anions OH and sodium
cations Na'.It's a highly caustic base and the alkali that decomposes proteins
at ordinary ambient temperatures and can severely burn chemical burns. It
readily absorbs carbon dioxide and moisture from the air and is highly soluble
in water. It creates a series of hydrates NaOH nH₂O.Note: The monohydrate
NaOH H₂O crystallises from the water solutions between the temperatures of
12.3 and 61.8 °C. "Sodium hydroxide", which is commercially available, is
often this monohydrate, and published data can refer to it instead of an
anhydrous compound. It is frequently used as one of the simplest hydroxides
alongside acidic hydrochloric acid and neutral water to demonstrate the
chemistry students' pH scale.Preparation of Caustic SodaSodium hydroxide or
caustic soda can be prepared by three successive methods as given below:
• Castner-Kellner process
• Nelson Diaphragm cell
• Loewigs process
