Horizontal and vertical two-phase separators engineered to split well effluent into gas and liquid streams — sized to API 12J and GPSA guidelines, with inlet diverters, mist extraction, and sour-service construction.
A 2-phase separator extracts gas from the liquids present in well effluent or process feed, allowing operators to measure and route each stream independently. Three mechanisms work in sequence inside the vessel: momentum reduction at the inlet, gravity settling through the vessel body, and mist elimination before the gas exits — each stage removing progressively finer liquid droplets from the gas phase.
Fintelius sizes every separator against both governing constraints simultaneously — gas capacity from droplet settling velocity (Souders-Brown) and liquid capacity from required retention time — then selects horizontal or vertical geometry to match the gas-to-liquid ratio and plot-space available.
Every separator follows the same disciplined path through the shop, whatever its orientation.
Gas rate, liquid rate, operating pressure & gas-to-liquid ratio are used to size the vessel against both gas-capacity and liquid-retention constraints.
Horizontal or vertical orientation and slenderness (L/D) ratio are selected to match the sizing basis and available plot space.
Shell is rolled and fitted with the inlet diverter, mist eliminator, vortex breaker, and instrumentation nozzles.
Welds are radiographed and ultrasonically tested; thick-walled sections undergo post-weld heat treatment.
The complete vessel is hydrostatically tested, coated, and prepared for shipment as a skid-mounted or standalone unit.
Best for low-to-mid gas ratios and high liquid volumes — larger L/D ratios (3:1 to 5:1) extend gas residence and improve foam management.
Suited to high gas-to-liquid ratio applications above roughly 10,000 scf/bbl, slugging service, and space-constrained installations — shorter L/D ratios (2:1 to 4:1) use the full cross-section for gas flow.
A compact alternative geometry for high-pressure, moderate-volume service where minimal footprint and weight are priorities.
Momentum reduction, gravity settling, and mist elimination work in sequence — no single stage does the whole job.
Deflector plates, half-open pipes, or proprietary devices reduce incoming fluid momentum so liquid droplets drop out at the inlet rather than carrying through the vessel.
The vessel body provides residence time for density-driven separation — heavier liquid settles down while lighter gas rises to the outlet.
Removes fine liquid droplets from the gas outlet stream by coalescing them onto a woven mesh pad ahead of the gas nozzle.
An alternative mist-extraction technology that redirects entrained liquid downward using a series of angled vanes, tolerant of higher liquid loading.
Positioned over the liquid outlet nozzle to prevent gas or oil entrainment as liquid drains from the vessel.
Low, low-low, high, and high-high level switches manage liquid retention and trigger shutdown before carryover or dry-out.
Plate rolling and head forming to the design diameter, length, and wall thickness set by the gas-capacity and retention-time sizing basis.
