Atmospheric pollution by harmful substances in the course of anthropogenic human activity is an urgent problem of modern industrial production. Grain processing enterprises are not an exception here and are currently characterized by a negative impact on the environmental security of our country. Relevant economic entities in the process of operation of elevator complexes in the operation of grain dryers actively emit hazardous to human health gas particles, reducing the number of emissions of which contributes to the technological implementation of special purification systems. In this work methods of adsorption purification of furnace gas emissions from carbon monoxide and nitrogen oxide are considered. As a sorption material it is proposed to use the waste of the enterprise of processing and storage of vegetable raw materials – grain waste. In the course of the study was studied the characteristics of the enterprise, made technological calculations of equipment. A new scheme for effective purification of gas emissions has been proposed, which will help reduce the concentration of carbon dioxide and nitrogen oxide. A calculation was carried out to determine the necessary consumption of sorption material to achieve the required residual concentration of these harmful substances, the prevented environmental damage to the environment was assessed when introducing the technology of cleaning gas emissions with grain waste.
