Coalescer - Wikipedia

A coalescer is a technological device performing coalescence.They are primarily used to separate emulsions into their components via various processes; operating in reverse to an emulsifier.. There are two types of coalescers. Mechanical coalescers use filters or baffles to make droplets coalesce while electrostatic coalescers use DC or AC electric fields (or combinations).
