Oily Water Separator (15 ppm) · Oily Water Separator
The Alfa Laval S.p.A. PureSOx-Multi-4-Closed is part of the PureSOx wet marine exhaust-gas cleaning system family used to reduce sulphur oxides in engine exhaust. Despite the category shown in the supplied equipment list, PureSOx is an exhaust-gas cleaning system rather than an oily water separator. Wash water contacts the exhaust gas so sulphur compounds are transferred from the gas stream into the liquid phase before the cleaned exhaust is discharged through the vessel's exhaust system. The Multi designation belongs to a PureSOx arrangement intended for vessel-specific integration of more than one exhaust source; the exact source count and duct arrangement must be confirmed from the project documentation. This listed variant is identified as closed-loop, in which wash water is recirculated and its chemistry is controlled with an alkaline additive while a controlled bleed stream is treated according to the approved design. The model suffix must not be used to infer a verified engine-power rating, gas-flow capacity or water-flow requirement; refer to the manufacturer documentation for the exact figure.

What our service work and the manufacturer documentation say about keeping this model running.
Review emission and wash-water monitoring trends and compare them with the approved operating record rather than relying only on instantaneous values. Inspect scrubber internals, drains, piping, pumps, strainers, spray equipment and valves for deposits, corrosion, erosion and leakage during planned shutdowns. Verify calibration and condition of compliance-monitoring instruments and check valve-position feedback, interlocks and bypass arrangements where fitted. Closed-loop and hybrid systems require additional attention to circulation-water chemistry, dosing and water-cleaning equipment; all acceptance limits and calibration intervals must come from the approved manufacturer and statutory documentation.
Carry critical wash-water pump seals and service parts, strainer elements, valve-actuator and seal components, approved sensor consumables and calibration items, representative process transmitters where operationally justified, spray/distribution parts where replaceable, control-system fuses and corrosion-resistant gaskets matched to the installed configuration. Closed-loop or hybrid plants should additionally carry configuration-specific dosing and water-cleaning consumables specified by the manufacturer.
