Abstract Using a new on-column filtration technique, the effectiveness of asphaltene antifoulants was determined by measuring the percentage of reduction of asphaltenes at process and near process conditions (up to 200°C such as heat exchangers). This methodology uses conventional HighPressure Liquid Chromatography apparatus (HPLC), is fast (
