Fluids entering collection systems may require processing by separation equipment for one or more of the following reasons.
• The fluid may contain compounds whose economic value justifies the expense of the separation equipment.
• The fluid may contain compounds incompatible with downstream components in the collection system.
• The fluid may contain hazardous compounds whose discharge to the atmosphere, whether before or after combustion, would be unacceptable on health, safety, or regulatory grounds.
All pressure relief and depressuring streams should be evaluated for the potential need for separation equipment prior to atmospheric discharge or flaring.
