ODOR REMOVAL

The deodorization process consists of a steam stripping unit that uses the effect of partial pressure to devolatilize the organics from the plastic. Shredded plastics leaving the washing line enter to the deodorization unit, in which steam is fed to strip the organic compounds. The process works at ambient pressure and only uses steam without additional chemicals.

SOLUTION-DEODORISATION TECHNOLOGY

The process improvements developed are based on the extraction of substances under suitable conditions, degassing or the use of additives.
To measure and improve this type of improvement, a good methodology of detection and identification of the substances causing the problem is essential, mainly by chromatographic analysis in specialized laboratories as Odournet´s.

RESULTS: CHEMICAL ANALYSIS

•Similar chromatographic profile
•Deodorised sample shows a decrease in VOCs

RESULTS: CHEMICAL ANALYSIS

Odor sensory analysis results have been confirmed by molecular analysis where a decrease from 55% to 80% of the VOCS concentration has been observed.
