The invention relates to the use, in a hydrocarbon distillate with a boiling temperature of between 150 and 450°C and a crystallization onset temperature as measured by Differential Calorimetric Analysis of greater than or equal to -50°C, preferably of -5°C to +10°C, of a homopolymer obtained from an olefinic ester of carboxylic acid of 3 to 12 carbon atoms and from a fatty alcohol containing a chain of more than 16 carbon atoms and optionally an olefinic double bond, as a compound for revealing the efficiency of filterability additives based on copolymer and/or terpolymers of ethylene and of vinyl ester of a carboxylic acid of 3 to 12 carbon atoms, and of a monoalcohol containing 1 to 10 carbon atoms. The invention is also directed to an additive composition comprising a conventional hydrocarbon filterability additive in combination with an efficiency reveal additive, and also to the combustion fuels, motor fuel and oil fuel that comprise these additive combinations.
L'invention concerne l'utilisation dans un distillât hydrocarboné de température d'ébullition comprise entre 150 et 450°C et de température de cristallisation commençante mesurée par Analyse Calorimétrique Différentielle supérieure ou égale à -50C préférablement de -5°C à +10°C, d'un homopolymère obtenu à partir d'un ester oléfïnique d'acide carboxylique de 3 à 12 atomes de carbone et d'un alcool gras comprenant une chaîne de plus de 16 atomes de carbone et éventuellement une double liaison oléfïnique, comme composé pour révéler l'efficacité des additifs de filtrabilité à base de copolymère et/ou tert-polymères d'éthylène et d'ester vinylique d'un acide carboxylique de 3 à 12 atomes de carbone et d'un mono alcool comprenant de 1 à 10 atomes de carbone. L'invention vise aussi une composition d'additif comprenant un additif classique de filtrabilité des hydrocarbures en combinaison avec un révélateur d'efficacité ainsi que les combustibles, carburant et fioul comprenant ces combinaisons d'additifs.
