Abstract

Abstract The analysis of statistical data showed that a large amount of plant waste is generated annually in oil and fat production plants, which must be processed and reused. The paper analyzes the problems of reusing sunflower oil production waste, which is characterized by a relatively high energy value: 1 ton of plant waste is equivalent to 0.625 tons of conventional fuel. According to the mathematical estimation, the actual total amount of impurities is 7.29%, in which major impurities constitute 25.7%. Studies have shown a high probability of oil – containing impurities – 37.25%. Therefore, it is recommended to process such impurities into fuel briquettes and technical oil to increase the profitability of sunflower oil production. For example, at the annual load of technological equipment of the Melitopol Oil Extraction Plant, in 250 days, at a daily processing capacity of 550 t˙day-1, an annual profit of 560,000 EUR is obtainable from the sunflower grain impurities processed into fuel and technical oil.

Highlights

The global lack of fossil energy resources in developed countries leads to the expansion of efficient use of alternative energy sources
Previous studies of oil and fat industry (OFI) enterprises revealed that the greatest attention was paid to the processing of industrial waste into fuel materials at Zaporizhzhya Oil and Fat Plant (OFP), Vinnytsia OFP, Vovchansky Oil Extraction Plant (OEP)
As a result of field research to determine the statistical characteristics of sunflower oil raw materials at the Melitopol oil extraction plant (MOEZ), qualitative indicators of sunflower oil raw materials arriving from different regions of Ukraine were studied

Summary

Introduction

The global lack of fossil energy resources in developed countries leads to the expansion of efficient use of alternative energy sources. Along with the use of solar and wind energy, biofuels, various solid organic materials, and biogas, the use of agricultural products is becoming more widespread (Tryhuba et al, 2020). Three main global trends can be observed in the development of rural bioenergy can be observed (Mikhailov et al, 2019): – reduction of total energy consumption; – increasing the use of renewable energy sources; – predominant use of solid biofuels. Efficient use of energy boilers requires the development of biofuel preparation technologies, automatic combustion process control systems and special materials of the combustion chamber (Sumets, 2016)
