Special Features of Adsorbent Application on the Base of Polyvinylchloride (PVC).

Abstract

The main goal of this work was implementation of high efficiency adsorption plant for recovery of different compounds with nondurable payout. There was offered technique on the base of application of adsorbent on the ground of polyvinylchloride (PVC). Application of PVC as adsorbent is nonconventional field of it appli-
cation. There was showed application of adsorbent on the base of PVC, which has porous nanoscale structure, for recovery of organic compounds (hydrocarbons, esters, aromatic compounds, chlorinated organics) from gas emissions. There was detected criterion of interaction of PVC with recovered organic compounds. The main advantages of adsorbent on the base of PVC in comparison with activated carbon are: incombustibility, absence of adsorbent's grains breakage in the course of maintenance, adsorption little to no heat liberation and temperature increasing, desorption under vacuum. By doing so, adsorbent has persistence to acids and alkali action. Adsorption process could be carrying out under environmental temperature, desorption is carrying out under rough vacuum (at least equalto 0, 2 atm) without vapor application. Technology is used during 15-20 years at two large enterprises of Russia for vinyl chloride recovery without adsorbent replacement. There was showed possibility for creation of high effective units for gas emissions treatment from petrol vapors.
