Process for selective separation and for the simultaneous increase in purity, of spent, fragmented, organic materials by means of aqueous media having chosen densities
Abstract:
Process for the selective separation, and for the simultaneous increase in purity, of two spent, fragmented, synthetic organic materials having different densities, mixed together or mixed with various contaminating materials to be eliminated, by means of dense aqueous media, each aqueous medium of which has a chosen density “ds” as threshold for separating said organic materials and contaminants, characterized in that the process comprises: a) a step of separating the mixture into two streams, a supernatant stream (a1) and a settled stream (a2); b) a step of separating the components of the supernatant stream (a1), by eliminating the supernatant fraction and collecting the settled fraction formed from the fragments of the first recyclable spent synthetic organic material; c) a step of separating the components of the settled stream (a2) by collecting the supernatant fraction and eliminating the settled fraction; and d) a step of separating the components of the supernatant stream by eliminating the supernatant fraction and collecting the settled fraction formed from the fragments of the second recyclable spent synthetic organic material.
Abstract(Chinese):

将具有不同密度的两种已消耗的，碎片化的合成有机材料选择性分离并同时提高纯度的方法，通过密集的水性介质混合在一起或混合在一起或与要消除的各种污染物质混合， 其具有选择的密度“ds”作为用于分离所述有机材料和污染物的阈值，其特征在于所述方法包括：a）将所述混合物分离成两股物流，上清液流（a1）和沉降物流（a2） ; b）通过除去上清液部分并收集由第一可再循环废合成有机材料的碎片形成的沉​​降级分，分离上清液流（a1）的组分的步骤; c）通过收集上清液部分并消除沉降馏分来分离沉降物流（a2）的组分的步骤; 和d）通过消除上清液部分并收集由第二可再生废弃合成有机材料的碎片形成的沉​​降级分来分离上清液流的组分的步骤。
