Abstract
Przedmiotem zgłoszenia jest sposób oczyszczania kwasu tere ftalowego (PTA) z surowego strumienia PTA uzyskanego sposobem recyklingu PTA. Sposób ten obejmuje dwuetapową filtrację przemywania placka filtracyjnego gorącą, a następnie zimną wodą, przedmuchiwania i suszenia placka filtracyjnego i na koniec przesiewania uzyskanego produktu do uzyskania ziaren o średnicy od 20 mikrometrów do 130 mikrometrów.The subject of the application is a method for purifying terephthalic acid (PTA) from the raw PTA stream obtained by the PTA recycling method. This method includes two-step filtration of washing the filter cake with hot and then cold water, blowing and drying the filter cake, and finally sieving the resulting product to obtain grains with a diameter of 20 microns to 130 microns.
