详细
The technology of liquid extraction treatment of wastewaters of the paint and varnish production facility using a three-stage spray extractor has been developed for the removal of butylglycol, phenyl isopropanol, acetic acid, and acetylacetone using isopropyl ether as an extractant. A mathematical model of extraction is presented that takes into account the hydrodynamics of countercurrent liquid flows, the mass transfer and mass exchange of liquid phases for each component. The differential cell model is applied to determine optimal parameters of the process, calculate basic dimensions of the spray extractor, and propose a three-stage process flowsheet with the minimum consumption of extractant at the ratio 1: 15 in relation to wastewater.
