• INLET SEPARATION

    Inlet Separation

    Separation is the process through which a two or three-phase mixture of gas, hydrocarbon liquids and/or water are split into their distinct phases. The separation process is via gravity settling of the different phases due to their differences in density and is aided by vessel design and internal devices. Once separated the individual phases exit the vessel for further processing.

TDE evaluates and makes design considerations to determine optimum efficiency and enhance phase separation. TDE's Inlet Separation Units incorporate design aspects to minimize upfront capital costs.

TDE offers either our Standard Pre-Engineered Modular Packages or Fully Customized Designs to meet varying project and schedule requirements.

PROCESS DESCRIPTION

Feed gas enters the separator vessel and flow is diverted by an inlet device in the inlet section, where the bulk gas-liquid separation occurs. The gas flow is distributed for efficient separation and allows the majority of liquid droplets to settle out due to gravity separation. Hydrocarbon liquids and water accumulate at the bottom of the vessel into corresponding light and heavy liquid phases separated by interface control, which exit the vessel.

The gas flows through the separator and is polished, typically by a mist eliminator, which removes liquid droplets and limits carryover prior to exiting the vessel and continuing downstream for further treatment.

DESIGN CONSIDERATIONS

Phase Separation
• Designed to induce gravity separation and allow accumulation of liquid
• Vapour area design manages maximum velocity to limit droplet carryover

Surge & Retention Time
• Optimized to ensure liquid/liquid disengagement
• Provide sufficient time for operator response to liquid level changes

Internals
• Enhance phase separation performance
• Optimized to maintain interface control

Filtration and Coalescers
• Provides additional removal for high solid and liquid loading
• Selection provides protection of downstream equipment
