Удосконалена методика визначення повної енергоємності продукції для багатопродуктових виробництв

Abstract

The total energy intensity of goods, labour and services as an indicator of energy efficiency is introduced in DSTU 3682-98 "Methods of determination of total energy cost of goods, labour and services", but some of its components listed in the standard still do not have clear algorithms for determining them. The article provides an overview of changes and extensions to the methodology presented in the articles of scientists of the Institute of General Energy of the National Academy of Sciences of Ukraine, who develop this methodology for more than 20 years. Authors propose such extensions and advancements to the methodology: the calculation algorithm of direct and technological energy intensity of goods production was advanced by the use of proportions for each product for multi-productive technologies, new calculation algorithm is proposed to assess energy intensity of labour and technological assets, also a set of hazardous pollutions was accounted in the method of assessments of abatement technologies energy intensity. The proposed advanced methodology could be used both for existing single- and multi-products technologies retrofit planning and for the design of new technological facilities taking into account a wide range of production factors including impact on the environment. Keywords: energy intensity of products, technology, direct energy intensity, total energy intensity, distribution of common energy costs
