Post-Treatment Protection

Gas from amine contactors, glycol dehydrators, or other treatment carries trace amine mist, glycol carryover, condensate, or process chemicals. Treated gas KO drums capture these contaminants preventing pipeline contamination, compressor damage, and sales gas specification violations.

Drum Configuration

Vertical vessel with treated gas inlet, liquid knockout section, coalescing stage removing aerosols, mist eliminator polishing gas, clean gas outlet to sales or compression, and liquid drain to recovery. Multiple stages ensure complete cleanup.

Operating Pressure

Matches treated gas pressure typically 300-1500 psig for pipeline applications. Design accommodates operating conditions with safety margin. Low pressure drop preserves gas pressure for downstream use.

Contaminant Removal

Amine or glycol mist from treating equipment. Water condensate from cooling. Hydrocarbon liquids from incomplete separation. Filter media and coalescers capture submicron particles and droplets achieving clean dry gas.

Material Selection

Carbon steel for sweet gas after treatment. Stainless steel where trace contaminants cause corrosion. Internal components resist chemicals from upstream processes. Design handles varying gas composition and flow rates.

Liquid Recovery

Separated liquids route to treating solution recovery or disposal. Amine and glycol return to circulation systems. Condensate goes to stabilization or disposal. Proper recovery prevents environmental releases and reduces chemical costs.

Applications

Pipeline sales gas final cleanup, compression suction protection after treating, fuel gas conditioning, gas plant outlet polishing, and any application requiring specification gas quality after treatment processes.

Gas Quality

Ensures gas meets pipeline tariff requirements for liquids, water content, and contaminants. Prevents custody transfer meter fouling. Protects downstream equipment and infrastructure. Critical for commercial gas delivery.

Level Control

Level-activated drains remove accumulated liquids maintaining drum performance. High-level alarm protects against carryover. Automated operation suits unmanned facilities. Simple controls integrate with treating systems.

Performance Benefits

Prevents specification failures and pipeline rejections. Protects expensive compression and metering equipment. Recovers valuable treating chemicals. Simple final cleanup with proven reliability.

Construction Standards

Design per ASME Section VIII for operating pressure. Materials suitable for treated gas composition. Filtration efficiency per gas specifications. Complete documentation with separation calculations.
