Caustic solution hydrogen an older process used to make sodium hydroxide is the leblanc process, which is a process that heats sodium chloride with sulphuric acid to make hydrochloric acid and sodium sulphate. A 01 mole% caustic soda (naoh) solution is to be concentrated in a continuous evaporator the solution enters the unit at 25°c at a rate of 150mol/min and is concentrated to 5 mole% at 50°c. Caustic soda is a basic feedstock in the manufacture of a wide range of chemicals it is used as an intermediate and a reactant in processes that produce solvents, plastics, synthetic fibres, bleach, adhesives, coatings, herbicides, dyes, inks and pharmaceuticals. Sodium hydroxide is a highly caustic base and alkali, that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns it is highly soluble in water and readily absorbs moisture and carbon dioxide from the air.

Membrane-grade caustic soda is replacing so-called “rayon-grade” caustic soda membrane and mercury-grade caustic soda prices are so similar that customers purchasing mercury-grade caustic soda can easily substitute it for membrane-grade caustic soda without seeing higher costs the use of this product contributes to mercury pollution.
Experimental observation for multi nozzle liquid jet ejector for chlorine-aqueous caustic soda system at laboratory scale to measure flow rates of operating liquid and air respectively the / flow rate is measured with the help of soap film meter (gm2) there are four sample points s0, s1, s2 and s3 to of caustic solution was adjusted. In the caustic regeneration section, air and liquid catalyst are injected into the mercaptide-rich caustic solution from the bottom of the extractor, and the mixture is fed to an oxidizer column, where the extracted mercaptans are oxidized to disulfides (rssr. Some other cleaning systems use air or a mixture of air and water as the propelling fluid but the expansion of the air as the cleaner exits the tube can convert the cleaner into a projectile and place the technicians at risk. Facilities use wet air oxidation for spent caustic treatment the purpose of this paper is to provide insight into the design of a wet air oxidation system as it is applied on a full scale basis for spent caustic treatment.
Essay: all organisms on earth depend upon water if the water consumed is adulterated, fatal changes may be the result for consuming organisms water is of great significance for people, since it is used for drinking and in cooking. Industrial pollution: types, effects and control of industrial pollution in order to provide daily needs of the growing population, different types of industries are setup to produce different products the industries use raw materials, process them and produce finished products caustic soda mercury, chlorine gas air, water and land 2. Wet air oxidation helps treatment facilities treat spent caustic liquors on-site instead of hauling the waste to costly off-site treatment and disposal facilities.
