HPS offers an Exhaust Gas Cleaning System (EGCS), also known as a scrubber, for the marine industry.

The IMO Annex VI on sulfur regulation calls for a 0.1% sulfur limit in Emission Control Areas (ECA) by 2015, and a worldwide limit of 0.5% by 2020 at the latest.

The HPS Scrubber System effectively removes sulfur and harmful particulate matter from the ship’s flue gases. The extensive ship building expertise and years of EGC system R&D experiences have led HPS to possess the optimal design and installation techniques of EGC system solutions.

HPS Scrubber

HPS is able to offer advanced solutions to meet the increasingly stringent maritime pollution control standards including IMO and other maritime regulations.

Through extensive research and development, HPS has been expanding its product line with innovative technologies to meet current, future, and the ever-increasing pollution control regulatory climate activity.

  • Quenching stage, using BOTTOM SPRAY with INNER PLATE

    Near the entrance of the scrubber, exhaust gases are quenched to
    the saturation temperature of H2O, simultaneously eliminating
    a large quantity of particulate matter.

    Naturally, droplets of absorbent liquid, which are provided
    by BOTTOM SPRAY, significantly eliminate SOx from the ship’s flue gas.

  • Absorbent spraying stage, with NOZZLE FREE TOP SPRAY

    Packing materials provide a huge amount of surface area in order to
    improve interaction between flue gas and SOx absorbent liquid,
    which is supplied by the NOZZLE FREE TOP SPRAY without any vibration.
