Title: Resource- and energy-saving technologies developed by JSC


Biography: Norov Andrey M


JSC "The Research Institute for Fertilizers and Insectofungicides named after Professor Y. Samoilov”(JSC“NIUIF”), the oldest (founded in September 1919) industry-oriented institute in Russia, has developed a number of innovative technologies in recent years. These technologies allow to recycle production wastes, increase the efficiency of natural resources consumption and reduce the negative impact on the environment. The technologies include, in particular:

1. An innovative, resource-saving process of joint processing of waste production of wet phosphoric acid (WPA) - phosphogypsum and fluorosilicic acid (FSA) into ammonium sulfate with simultaneous neutralization of fluoride compounds without using lime. This technology is currently being implemented at one of the large Russian plants.

2. Improved WPA technology by dihydrate-hemihydrate method in relation to various types of phosphate raw materials. This technology makes it possible to consume natural phosphate raw materials more effectively and fully, and to process production waste - phosphogypsum into gypsum binders and cement due to a lower content of impurities in it. Implementation of this technology in a number of Russian and foreign plants is under consideration now.

3. Innovative, no-analogue technology of slow-release granular PK-, PKS-, NPKS-fertilizers. This technology allows to process a number of wastes and by-products: conversion chalk, phosphogypsum, sludge from sodium tripolyphosphate production, etc. The technology was successfully implemented in 2014 at one of the Russian plants – JSC Metakhim (Volkhov, Leningrad Region).

All listed environmental technologies are protected by Russian and Eurasian patents.

JSC “NIUIF” continues to work on compound use of natural resources and reducing the environmental impact.
