Technical Overview

The ENVI-Clean™ system is both highly efficient and cost-effective at removing acid gases. The system utilizes its highly efficient patented turbulent head and a further polishing head, both of which use fluid recirculation and an on-demand approach for reagent addition.

Helping Coal Clean Up

Burning coal which normally has a variable high Sulphur content in the atmosphere is terribly polluting and responsible for a high proportion of land based smog in areas of the world where coal remains an essential energy source.

Today, no continent is at greater risk than Asia. India, home to 1.3 billion people, also has 22 of the 50 most polluted cities in the world.

Developing countries still rely heavily on coal burning power stations, with new coal power plants still being built in increasingly large numbers in some parts of Asia.

Although acknowledged to be one of the largest polluters, China is at the forefront of emission control technology. Having recognised how urgent the emissions problem is, the Chinese Government are supporting many new initiatives and have chosen to form a Joint Venture partnership with Pacific Green Technologies to assist in reducing the country’s air pollution.

TurboHead™ Technology

At the heart of our technologies lies the secret of the unique patented process which forms the basis of the ENVI-Marine™ and ENVI-Clean™ systems.
TurboHead Image

Technically the company's philosophy from the beginning has been to build a device providing the maximum possible molecular contact area between the harmful exhaust gases and the neutralising reagent. This allows the system to be smaller and more efficient, therefore more cost effective in terms of both capital cost & operating cost for any given capacity.

Pacific Green Technologies has successfully achieved this by use of a specially designed foaming TurboHead™ which creates convection and turbulence in a unique way.

The patented scrubbing heads all have this unique reaction process, combining turbulence and circulation of the exhaust gas maximising contact with the chosen reagent solution, be it plain seawater, Limestone, or Sodium Hydroxide solution.

The mandate throughout has been to fulfil the demands of our customers who want us to produce the most efficient emission control solutions in the most cost effective way.
