Features of setting up a complex, combined and zero-waste gasifier plant

Abstract

Purpose. Setting up and implementation of complex, combined and non-waste power-chemical plant based on underground coal gasification with regard to analysis of its technical and economic efficiency. Methods. Research into the reliability of the gasifier plant components was performed by determining the sequence of processes and operations during underground coal gasification technology at all levels of the process. Findings. It was established that high reliability of coal gasification is ensured by stability of all constituents of the technological elements of the process. The basic steps of combining power and chemical plant specializing in synthetic hydrocarbons production are described. During gasifier plant operation, upgrading of equipment at the general level of mechanization between 0.5 – 0.7 will not lead to a serious increase in productivity. Therefore, it is necessary to allocate means and efforts to completion of mechanization of all production processes. Originality. The efficiency of mechanization and automation of processes at a gasifier plant is expressed through the formula of automatic control. We have identified dependencies describing changes in the mechanization efficiency of all technological units of the gasifier plant and productivity growth due to reducing the number of manufacturing operations. Practical implications. Analytical research testifies that effective functioning of the gasifier plant is ensured by automation of all technological processes. Computer system conversion requires additional investments which exceed the costs of mechanization by 1.25 – 1.4 times.
