Download the Pall report outlining an installation experience at The Dow Chemical Company (Dow) in Freeport, Texas. The installation covers the use of high efficiency liquid–liquid coalescers and filters to extend the steam cracker service life between decokings. The naphtha feed was supplied by marine transport and contained significant salt water contamination. An economic evaluation of the savings due to improved operation efficiency and the payback period for the coalescer system is provided.

The installation of the high efficiency coalescer–filtration system was found to have a payback of less than ten months based on extended furnace run times alone, assuming that ethylene production is limited by furnace availability.
