Oil & Gas production
This includes all processes of phase separation, wastewater treatment, first treatment and pumping or compression of liquid and gaseous hydrocarbons extracted from the respective oilfields, and final reinjection of gas or water into the oilfields. Plants are normally located close to extraction sites and can therefore be located onshore or offshore. In the latter case they can be located on fixed or floating platforms or on ships (FPSOs).
Different separators, such as ‘Test separator’, ‘Production separator’, ‘Free Water KO Drum’, ‘Oil coalescer’, ‘Flare KO Drum’ can be used in the separation of phases, with different configurations and types of gas-liquid or liquid-liquid internals.
Depending on the operating conditions (temperature and pressure) and properties of the process fluids (flow rate, density, viscosity and surface tension), Costacurta selects and designs the correct set of internals guaranteeing efficiency and minimising pressure drop, weights, dimensions and the costs of the internals and of the separators they are installed in.
Horizontal gas-liquid-liquid separator
Typical horizontal gas-liquid-liquid separator fitted with cyclonic inlet distributor, perforated plate calming baffle, VICO-Pack, anti-turbulence slats, VICO-Straightener, VICO-Vane droplet separator and sand jetting system. Horizontal gas-liquid-liquid separators with this combination of internals are widely used when gas and liquid loads are high and separation of liquid-liquid primary dispersions is required. They are the ideal solution for offshore and FPSO applications and for the retrofitting of existing equipment.
Horizontal liquid-liquid separator
Typical horizontal liquid-liquid separator with perforated pipe inlet distributor, perforated plate calming baffle and VICO-Pack. The presence of a VICO-Pack allows treatment of a slightly foul fluid stream. In the case of clean fluid, a VICO-Tex® Coalescer instead of a VICO-Pack allows higher separation performances to be obtained.
Vertical gas-liquid-liquid separator
Typical vertical gas-liquid-liquid separator equipped with vane feed inlet distributor, perforated plate calming baffle, VICO-Pack, VICO-Tex wire mesh agglomerator and a set of axial VICO-Spin cyclones. This type of separator is recommended when it is necessary to optimise dimensions where the quantity of gas is much greater than that of the two liquid phases.
