Features of introduction of biogas technologies in the conditions of industrial enterprises of the metallurgical industry

Abstract

The paper analyzes and classifies the advantages and disadvantages of existing technologies for cleaning hydrogen sulfide and increasing calorific value by enriching biogas mixtures from various sources. Among them are identified those that are most acceptable from an economic point of view for implementation in heavy industry. A list of available methods and relatively inexpensive reagents for the treatment of biogas in the conditions of metallurgical enterprises, among which technical and ammonia water, waste from steel pickling processes in the form of iron sulfate, and others, is established. The main fuel characteristics of biogas of various origin and composition and natural gas are compared in determining the directions of using alternative fuel in industrial heating plants. It was determined that thermal and heating furnaces have the greatest potential for adaptation to biogas combustion, since such units are able to work in a wide range of quality, fuel consumption and calorific value. Since the scientific base regarding the possible conversion of these plants to biogas is unstructured, and in many aspects is absent, the creation of appropriate methods, mathematical apparatus and algorithmic tools in this direction is an urgent task.
