Flux Oil is an aromatic solvent with high solvency power, high boiling range & flash point. Owing to these properties it is used as a cooling, diluting & decanting solvent at Ethylene Cracker’s Quenching towers.

Reactors produces a hot intense mixture of feed, reactants, inerts and co. products. The mixture need to be cooled and separated. In an ethylene plant the mixture is partially cooled by heat exchangers and then in a quench tower. The quench tower has heat transfer sections that remove the heat at different levels.
