Process for selective elimination of functional organic compounds from a liquid medium

摘要

The procedure for eliminating at least one organic compound from a liquid medium consists of circulating a gas flow through the liquid at a rate of 10 - 600 ml/min-1 and simultaneously subjecting it to ultrasound waves at a frequency of 15 kHz to 1.5 MHz while the liquid is at a temperature of 10 - 100 deg C and a pressure of 1 - 10 bars, e.g. at ambient temperature and pressure. The organic compound contains at least one atom of nitrogen, oxygen, sulfur, phosphorous, and atoms of halogens such as chlorine, bromide and iodine. The liquid comprises an extractant and a diluent selected from alkanes such as TPH, alcohols, carboxylic acids and dodecane.
