Purification of Gas Emissions from Nitrogen Oxides Using Peat-alkaline Sorbent

Abstract

The possibility of neutralizing gas emissions from nitrogen oxides by a peat-alkaline sorbent containing as an alkaline component ash from the incineration of sunflower husks is considered. Spent peat-alkaline sorbent is expedient for use in the development of composting mixtures together with the waste of brewing industry – spent grains and excess active sludge of treatment facilities, while the range of optimal compositions of composting mixtures (% by mass) is limited: waste sorbent – 20–60; spent activated sludge – 20–50; spent grains – 20–40. The content of components of composting mixtures was determined by the simplex lattice method. The results are presented in the form of Gibbs concentration triangles, for which a complex of physicochemical parameters (water-soluble substances, calcium and magnesium cations, soil acidity, nitrates according to Grandval-Lajoux) will have the best values for the growth of agricultural plants.
