Petrochemical Quench Water

Improving Product Quality. Reducing Corrosion.

Achieve Maximum Contaminant Control In Quench Water With Advanced Filtration & Separation Technology

In ethylene production, failure to mitigate contamination of processing streams can result in poor product quality, fouling of equipment, and costly maintenance downtime. 

 

The reaction that forms ethylene from naphtha feeds produces the liquid hydrocarbon byproduct pyrolysis gasoline (py-gas). Heavy oil from the oil-quench tower may be present from carryover into the quench water along with the py-gas. To re-use the quench water for steam production, it must be processed to remove hydrocarbon contaminants including quench oil, py-gas, or other particulates. Failure to properly treat quench water will cause fouling of heat exchangers and boilers, lead to poor separation in stripping units, and increase energy consumption. 

 

When applied to quench water applications, Pall separation and filtration technology is proven to extend the service life of the stream stripper between cleanings, reduce fouling and maintenance of heat exchangers, lower steam use, and yield a higher recovery of py-gas. Pall prefilters efficiently remove hydrocarbon contaminants from quench water, while liquid/liquid coalescer systems break oil emulsions to reduce oil levels in the final water to less than 20 ppm even if the interfacial tension is 0.5 dyne/cm. 

 

The horizontal PhaseSep® Liquid/Liquid Coalescer effectively removes py-gasoline from quench water, which improves efficiency of steam system and py-gas recovery while also reducing operating and maintenance costs. The vertical PhaseSep® Liquid/Liquid Coalescer separates water from py-gas, minimizing the carryover of hydrocarbons to the steam generators for improved product quality and reduced corrosion. Downstream of the water quench tower, Profile® II Cartridges improve overall performance of sour gas treating operating. The SepraSol Liquid/Gas Coalescer removes compressor lube oil from ethylene and other hydrocarbon gases, reducing lube oil losses while improving product quality and equipment reliability.
