Sulfur produced in the form of dirty gas from big engines & boiler exhaust is very dangerous for the environment. To reduce Sulphur emissions, a scrubber system is used to remove harmful elements from gases and convert sulfur into sulfate (the end product from the scrubber system) for easy & safe discharge. They also need the scrubber to remove 60% to 90% of particulate matter (PM), including a portion of small PMs (10 and 2.5 microns, and ultrafine) & it allows vessels to use HFO; a residual fuel with high energy content which is difficult to refine.
CLOSED LOOP SCRUBBER SYSTEM
- Harmful gases from ship engines & boiler exhaust enter the scrubbing station through various chambers where a high number of droplets rapidly capture the errant particles in the process stream
- MgOH2 is added to the scrubbing water circulation to maintain the process pH and consequently the Sox removal efficiency. Simultaneously, a small bleed-off is extracted from the loop to remove accumulated impurities, and fresh alkaline water and MgOH2 is added
- Alkaline water (Sodium Hydroxide/ MgOH2) is sprayed on gases in the form of scrubbing clouds
- Scrubbing water passes through the packing bed and is collected and removed through the bottom.
- The water absorbs SOx emissions, heat, and other components from the exhaust gas stream
- The bleed-off having traces of oil & combustion elements and its pH is typically closer to neutral is transferred to the emulsion breaking water treatment unit
- Clean effluent from the treatment unit is discharged overboard after quality monitoring or led to the effluent holding tank when overboard discharges are to be avoided.
PROGRESSIVE CAVITY PUMP APPLICATIONS IN SCRUBBER SYSTEM:
- To transfer MGOH2 to the Alkaline Water Unit
- To dispose of sludge from the Water Treatment Unit
