Determination of environmental indicators of different recycling options for spent-catalyst of petroleum hydrocarbons cracking based on life cycle assessment

Annotation

The article discusses the application of life cycle assessment (LCA) to determine the environmental indicators of different recycling options for spent - catalyst of petroleum hydrocarbons cracking, the formation of which is a problem for refineries. It is shown that at the present time in Belarus, Russia and other CIS countries there is a lack of effective tool for determining the environmental indicators of products (services), while in the international practices it is a life cycle assessment. The specific features of the LCA methodology and specialized techniques are discussed. The results of the LCA for determining the best technology of spent-catalyst recycling are shown.
