CONDUCTING AN ENVIRONMENTAL ASSESSMENT OF THE SUGAR PLANT'S SATURATION GAS EMISSIONS WITH THE ESTABLISHMENT OF MAXIMUM PERMISSIBLE STANDARDS FOR CARBON MONOXIDE AND DIOXIDE

Abstract

Subject. The current state of human development requires a reasonable approach not only to obtaining high-quality competitive products, but also to reducing the amount of harmful emissions into the environment as a result of the production of these products. In particular, there is an urgent need to reduce the amount of harmful emissions of carbon dioxide (CO₂) and carbon monoxide (CO) generated during the firing of limestone in the kilns of sugar factories and contained in the souring gas used in the technological process of sugar production. Purpose. The purpose of the work was to conduct a monitoring study of the maximum permissible emissions of CO and CO₂ from saturation gas and to conduct an environmental assessment of these emission components for a sugar plant. Methods. The analysis and monitoring study was carried out using methodological approaches used in domestic and international practice. We used modern electronic portable gas analyzers, an electronic thermometer, and an anemometer to quantify the components of saturation gas and air emissions. Results. It has been determined that the main components of saturation gas emissions include carbon monoxide (II) – CO, also known as carbon monoxide, carbon dioxide (IV) – CO₂, carbon dioxide, oxygen – O₂, nitrogen - N₂. The maximum permissible standards for saturation gas emissions from stationary sources in the technological process of sugar production were generalized. It is established that the CO content in the saturation gas depends on: the type and amount of fuel for limestone firing; the size of the charge components; the fractional composition of limestone and the useful height of the furnace; the displacement of the heating zone or the firing zone in one direction or another; inhibition of gas extraction from the furnace. It has been analyzed that the reduction of carbon dioxide emissions at a lime-carbonation plant is significantly influenced by the hardware design and construction of carbonizers. Recommendations for minimizing the amount of carbon dioxide and carbon monoxide emissions from the saturation gas into the atmosphere are proposed, and directions for reducing CO₂ emissions per unit of output are suggested. Scope of results. Sugar enterprises will receive data on the assessment of pollutant emissions and their reduction in the technological process of sugar production.
