utilization

It was considered the question of accumulation and reuse of construction waste. It was proposed methods of recycling construction waste into building materials.

The technological scheme of reprocessing the systems on the basis of concentrated nitrate acid containing compounds of iodine is presented. The offered scheme allows to reach the degree of utilization that exceeds 99 %. Наведено принципову технологічну схему переробки систем на основі концентрованої нітратної кислоти, яка містить сполуки йоду. Схема, що пропонується, дає змогу досягнути ступеня утилізації, що перевищує 99 %. 

The paper contains the results of experimental study of visbreaking process with the use of organic part of asphalt-resin-paraffin deposits (ARPD) as a raw material component. We studied the influence of ARPD amount as the additive to tar on the output fuel fractions and their qualitative parameters. The proposals on modernization of the industrial visbreaking scheme with blended raw material were made. The analysis of economic performance of the modernized process was carried out.
