AM-Scrubber-500 closed-loop

Andritz Marine AM-Scrubber-500 closed-loop is identified in the source list as a exhaust gas cleaning system (scrubber). It is installed in the exhaust path of an engine or boiler together with pumps, treatment equipment, monitoring and discharge or residue-handling systems. Its purpose is to reduce regulated exhaust emissions using the approved scrubber process fitted to the vessel. The source record provides no additional model-specific operating figure beyond the listed designation and category. Scrubber tower, washwater or reagent supply, pumps, valves, sensors, control software and effluent handling form an integrated compliance system. The exact model designation and any source process note distinguish gas-flow capacity and operating configuration from neighboring scrubbers; refer to the manufacturer documentation for the exact figure.

Common failures & inspection points

Washwater or circulation-pump failure caused by wear, blockage or electrical faults, resulting in low flow and an emission-compliance alarm
Nozzle or tower fouling caused by soot, scale or deposits, resulting in poor gas-liquid contact, rising backpressure or reduced treatment performance
Sensor or analyzer drift caused by contamination, calibration error or electronics faults, resulting in implausible emissions or washwater readings
Valve, reagent or dosing failure caused by actuator, blockage or control faults, resulting in incorrect process chemistry or unavailable operation
Corrosion or leakage caused by acidic washwater and aggressive condensate, resulting in thinning, visible leakage or damaged piping and tower internals

Service & Maintenance

Inspect circulation pumps, strainers, nozzles, tower internals, valves, dosing equipment, analyzers and drains according to the approved maintenance plan. Monitor exhaust backpressure and process indications and investigate recurring compliance alarms promptly. Clean sensors and sampling lines and maintain calibration records required by the approved monitoring scheme. Inspect washwater piping and tower structure for corrosion, leakage and coating deterioration. Function-test automatic bypass, changeover and alarm sequences using approved procedures. Refer to the manufacturer documentation for the exact figure for emissions limits, dosing rates, water-quality and maintenance settings.

Replacement Parts

Keep pump seals and bearings, nozzles, strainers, valve actuators, analyzer consumables, sensor parts and manufacturer-recommended control modules. Corrosion-resistant gaskets and piping components should match installed materials. Critical compliance equipment may justify strategic spare analyzers or pump components.
