The process is to manufacture pharm-grade salt. Main uses are in pharmaceutical industry. Pharmaceutical grade sodium chloride has many applications in injections, hemodialysis, oral rehydration salts (ORS), channeling agents/ osmotic agent, and dietary formulations etc.
- It is a combination of chemical and physical method to separate the impurities to get the pharma-grade salt.
- The process does not use expensive BaCl2 which is toxic in nature.
- This process can be scaled-up as a continuous process without the necessity of time-consuming recrystallization step.
- The production cost is less to sustain in the market.
- Complies with the specifications of IP grade
Technology validated in lab scale at Kg level in CSIR-CSMCRI ESF/ pilot plant
Few companies have approached us for discussion regarding commercialization scope with capacity in the range ~250 ton/month. As there are no major manufacturer of pharmaceutical sodium chloride in India, indigenous process developed can fulfill both domestic need and offers export potential.
The process is environmentally friendly. The solid by-product magnesium hydroxide along with other metal hydroxides can be used for derive other magnesia chemicals.
Raw NaCl (sea/subsoil brine), NaOH/CaO/Na2CO3
Brine tank with agitator, Nutsche filter, single/Multi-stage evaporator, ultrafiltration unit, centrifuge, process pump, dryer
Production cost of the salt will be around ₹6-7/kg.
Technical specification of each component, design drawing & layout, installation & commissioning, demonstration, basic training for the process (SOP). License fee and other financial details would be provided on request.
