Production of Sodium Hexametaphosphate

Abstract

Aim of this study is to undertake a complete analysis that will lead to an integrated design in chemical engineering. Which plant generates sodium hexametaphosphate with a predetermined production capacity consideration Aspects such as plant process unit designs, process flow diagrams, cost
calculations, operating parameters, equipment size, construction materials, and safety considerations will be considered in the research. The project utilities are the theoretical and practical application of mass transfer, heat transfer, fluid dynamics, unit operations, and process control. The sodium
hexametaphosphate, which is a polymer of sodium orthophosphate, is the objective product of plant by sodium hexametaphosphate. It is widely used as a food quality improver and preservative in the food industries, pharmaceutical industries and cosmetics, acting as a water softener in boiler water of power plants and other industrial water. SHMP will be manufactured in this project using a neutralization process followed by melt polymerization at elevated temperature. The required reaction is endothermic, yielding 90-92 percent overall. The project's goal is to produce 100 kg of SHMP per year. Three major components resolve uncertainty in this plant: a reactor, a crystallizer, a filter, and mixing tanks. Pumps, a rotary drier, and a condenser are all included. All must be constructed and operated in accordance with this capacity.
