Abstract
The method enables the antihydrate compounds contained in a condensed-hydrocarbon liquid feedstock arriving through pipeto be extracted. The liquid feedstock is brought into contact, in zone ZA, with a non-aqueous ionic liquid having the general formula QA, where Qdesignates an ammonium, phosphonium, and/or sulfonium cation, and Adesignates an anion able to form a liquid salt. The antihydrate compounds in the liquid hydrocarbon feedstock evacuated through pipeare eliminated. The ionic liquid charged with antihydrate compounds is evacuated through pipe, then introduced into evaporator DE to be heated in order to evaporate the antihydrate compounds. The regenerated ionic liquid is recycled through pipesandto zone ZA. The antihydrates are evacuated through pipe
