TYPE 31L-CLC / L1C COALESCING GAS-LIQUID SEPARATORS

Droplet separators 99% efficient for droplets >5 microns

  31L-CLC (L1C) Separator Specifications

Fully welded pressure vessel fabricated to ASME Code Section VIII Division 1 with stamp. No serviceable or moving components — requires zero maintenance. This is a two-stage design: the first stage uses a coarse mesh pad to coalesce droplets larger than 5 microns into droplets larger than 10 microns; the second stage uses the standard centrifugal action (indirect pathway, inertia and gravity) to separate those droplets with 99% efficiency.

This design is more costly than a standard 31L/L1 separator because the body is flanged, allowing the mesh pad to be inspected, cleaned or replaced if required.

Separates entrained droplets and particles larger than 5 microns in diameter with 99% efficiency.

Horizontal installation: Maximum separation rate is equivalent to 5% of its maximum rated mass flow capacity and will not separate liquid slugs.

Vertical installation (downward flow): Maximum separation rate is equivalent to 20% of its maximum rated mass flow capacity and will separate liquid slugs.

The required separator size is determined by vessel length and diameter, not necessarily by the pipeline size. Nozzles are sized to match the pipeline into which the separator is installed.

Typically manufactured from pipe; can also be fabricated from rolled plate. Standard materials are carbon steel, 304L stainless steel and 316L stainless steel. Other alloys are available when required. Common customizations include support legs, additional ports and non-flanged connections.
