Leading performance

ENVI‑Marine™ performance comfortably meets the required emission limit regulations for both ECA and IMO 2020 regulations in either ‘open’ or ‘closed’ modes.

Small, flexible footprint

The ENVI-Marine™ System is small compared to most other systems. Our patented TurboHead™ technology allows for a footprint that is considerably smaller without compromising on efficiency.

Attractive CAPEX / OPEX

The advanced TurboHead™ technology, careful material selection and skilled engineering design ensure competitive initial pricing and cost effective operation and maintenance.

Unrivalled Capacity

Meeting the challenge of fitting the world’s shipping fleet with exhaust gas cleaning systems is no easy task. Right now Pacific Green Technologies are producing one exhaust scrubber every 48 hours from their six factories in China.

The ENVI‑Marine™ Exhaust Gas Scrubbing Device

The ENVI‑Marine™ process is a simple concept. The flue gases are first quenched, then cleaned, by specialized frothing through pure seawater, using our patented TurboHead™ process before being discharged as harmless salts.

ENVI‑Marine™ systems are fully flexible and can be supplied as open loop, open loop hybrid-ready, and hybrid systems capable of both open and closed mode operation.

For vessels running heavy fuel oil, this system offers industry-leading ROI and will clean the exhaust to international emission standards far into the future.

Functions by:

  • Using the natural alkalinity of seawater to absorb SO2 emissions produced by marine engines
  • Post treatment discharge of neutralized sulphur into sea
  • Using caustic soda (NaOH) as a supplemental reagent when transiting areas with low seawater alkalinity

Flexible layout due to:

  • Patented horizontal head
  • Potential for component separation
  • Able to configure footprint to fit space available
  • Compact footprint due to efficiency

How does it work?

Water is continuously sprayed down onto the TurboHead™ Structure where it meets gas flowing upwards. The unique patented design of the TurboHead™ causes the gas and water to mix and create a turbulent ‘froth’, sometimes referred to as ‘foam’. It is the maximum surface area of the froth where the reaction takes place to clean the exhaust gas.

  1. Nozzles, with carefully calculated water volume
  2. ‘Froth’ Layer, generated by interaction of gas and water
  3. Baffles, designed to maximise interaction
  4. Mesh, precision designed to encourage reaction

Open Loop or Closed Loop?

Depending on the operating area of a ship, it may be preferable to have an open or a closed loop system. Many ships operating close to shore, or spending a lot of time in control zones will opt for a closed loop system. Ships that spend most of their time on the open sea opt for a open mode system.

Open Loop

Single pass raw seawater, scrubber effluent returned to the sea.

Closed Loop

No overboard discharge permitted. Washwater is recirculated with NaOH added to neutralize sulphur. Solution is processed and contaminants are stored for disposal ashore.

Customised for you

1. DISCUSSION > PROPOSAL > CONTRACT

Our expert team of Pacific Green Marine engineers will discuss your fleet requirements and work closely with you to create a costed proposal for deployment with minimal impact.

2. SURVEY > PLAN > BUILD

Once the proposed approach is agreed our Global Service Team will survey your fleet, formulate a plan and then meet your vessels in a port of mutual convenience where an expert team will install your ENVI-Marine device from a combination of prebuilt and custom built components

3. IMPLEMENT > TEST > COMISSION

Once fleet vessels are launched back to sea with fully tested ENVI-Marine technology in place, we work with you to plan out a service schedule. Also operate with the peace of mind that our Global Service Team are on hand to respond to any support you need while at sea.

Our global team of advisors with years of combined experience in the marine sector are on hand to discuss your project
