In Compressor Trains, or more commonly called Knockout Drums or Gas Scrubbers, small amounts of liquid entrained into the suction side of gas compressors can cause significant damage requiring a plant shutdown for repair or replacement. Therefore, effective mist elimination at both the feed stage and inter stage becomes extremely important.
DEMISTER® mist eliminators are often used to help protect this valuable rotating equipment from entrained liquid. If operating within its hydraulic limit, DEMISTER® mist eliminators remove entrained liquid droplets based on the impaction collection mechanism.
If the existing equipment is operating above its hydraulic limit, DEMISTER® high-capacity mist eliminators or DEMISTER-PLUS mist eliminators can be a very effective debottlenecking tool. The existing drum can often be retrofitted with new internals, which avoids the need to replace the existing drum with a larger drum. It is quite common that these retrofits can be completed without welding, which eliminates the need for ASME recertification.
On the lubrication side of the compressor, FLEXIFIBER® type BD mist eliminators help prevent emission of sub-micron lube oil droplets from exiting the lube oil reservoir vent line.
