Economic aspects of dust collecting from exit gas and aspiration exhaust in refractory production

Abstract

An economic concept of protecting the atmosphere from dust exhausts in refractory production is proposed. The efficiency of measures intended to decrease atmospheric pollution is considered at two levels: primary level -lowering the damage caused to the environment by decreasing dust exhausts: secondary -an integrated socioeconomic effect (improving the living standard of the population and increasing national wealth). A procedure is recommended for estimating the economic damage to company fixed assets caused by dust exhausts.The estimate of the socioeconomic efficiency of measures taken to protect the ambient medium from dust exhausts is determined as the difference between the cost (damage) with or without a system for atmosphere protection from dust emission. In the production of refractory materials the dust components emitted in the atmosphere contain substantial quantities of materials that have to be recycled in the technological process. Figure 1 shows the ratio of the atmospheric protection cost to the damage cost and the range of minimal overall costs corresponding to a certain range of the weight concentration of dust [1].The authors in [2] analyze the economic efficiency of measures intended to decrease the atmospheric pollution at two levels: the primary and the secondary ones. The primary level involves lowering the damage caused by a negative impact on the environment, improving its state by decreasing dust exhaust into the atmosphere. The secondary (integrated socioeconomic) level involves the improvement of the living standards of the population and increase in production efficiency and national wealth. The total (absolute) economic effect of all environment-protecting expenses E e is characterized as the ratio of the total annual economic effect to the
