TECHNOLOGICAL PROJECT FOR THE PRODUCTION OF SODIUM PYROPHOSPHATE

Abstract

The article presents the main physico-chemical properties of sodium pyrophosphate, application area and calculations of the material flow of production. It is noted that sodium pyrophosphate is widely used as a raw material for a buffering agent, emulsifier, dispersant, water softener, agent for removing oil, deodorizer. Due to the high demand for pyrophosphate, the necessity of its production, investigated methods of technology improvements and improve the quality of the final product. The article presents the results of calculating the material balance for obtaining sodium tripolyphosphate with using soda ash. At the same time, the possibility of formation of by-products is noted, their quantitative indicators and types of compounds according to the methods of choice of analysis. According to the scope of use of sodium pyrophosphate in the food industry, methods are given for cleaning the product from impurity components.
