LIQUID DISSOLVER COMPOSITION, A METHOD FOR ITS PREPARATION AND ITS APPLICATION IN METAL SULFIDE REMOVAL

摘要

The present invention relates to an aqueous composition, comprising 1. 5 to 50 wt.-% of at least one polymeric carboxylic acid having a weight average molecular weight from 1500 to 50.000 g/mol, determined by gel permeation chromatography against polystyrene standards, or its salt; 2. 2 to 28 wt.-% of at least one H+ ion releasing monomeric acid having a molecular weight of less than 500 g/mol; 3. 2 to 30 wt.-% of at least one surfactant.
