Improve contaminant control in ethylene production

New separation methods effectively remove aerosols and particulates that compromise heat-transfer surfaces

Wines, T. H., Pall Corp.

Managing contaminants in ethylene production is critical. Contaminants in processing streams can compromise production efforts, foul major equipment operations such as heat exchangers, compressors, etc., and cause unscheduled shutdowns. Many processing streams within the ethylene unit are inter-related; thus, removing contaminants early within the process can reduce fouling-related issues in downstream process units. Filtration and phase separation methods can be applied in various locations in ethylene units to provide benefits. Potential contaminant removal applications include: feedstock treatment, quench water, caustic treating, acetylene converters and fuel-gas systems. Using cont
