Frequently Asked Questions

General:

Yes, Clairion technology is based on utilizing unique liquids and chemical processes that are protected by a range of 6 patents 3 of them already granted.

Clairion’s unique absorption process efficiently removes pollutants emitted in flue gas streams regardless of its industrial applications and sources. Our technology is completely scalable and can be applied to various industrial plants and processes emitting pollutants regardless of its flue gas flow rate and concentration.

Clairion technology has been proven in the field under real conditions. It hasn’t yet been implemented in large full commercial scale. However, we are running two successful operational pilots in power plants in Israel and in Europe and are in process of implementing a 3rd one. We are in process of commercialization.

Clairion’s unique absorbing liquid is based on ionic liquids – a new type of solvent which is safely used in many industrial processes & chemical /gas absorption processes today. Some of its unique properties are the fact it isn’t flammable or explosive and doesn’t create any odor problems.

Our absorbing liquid is based on ionic liquid which is salt in a liquid form and has no measurable vapor pressure. Due to unique liquid properties and our engineering design we are overcoming the typical challenge of evaporation and runaway of droplets.

C-HgR Related:

The C-HgR™ is a standalone solution that is custom made and can be installed as a retrofit. The C-HgR™ can be integrated with almost any APC set up without impacting existing installations and processes.

The C-HgR™ is a fully regenerative process and unlike most commonly used solutions does not produce any wastes or contaminated byproducts besides the very small amounts of mercury that are separated and stabilized as pure mercury sulfide (“Cinnabar”, HgS) for safe disposal.

The amount of mercury that can be captured in our unique liquid can reach up to 50% Hg by weight. However, the actual operational mercury load within the liquid should be adjusted on a case-by-case basis based on the flue gas Hg concentration and the recovery approach for the Hg and the liquid. Only small amount of the liquid will be treated/regenerated annually offsite as part of the service.

From performance aspects, our unique process can be installed prior to or following the SO2 treatment technology. What eventually determines its location is customer ‘s needs, site plan and conditions.

The C-HgR™ process handles metallic and ionic Hg (as these are the major ones in the flue gas at high temperatures), as well as mercury compounds (absorbed onto the surface of other particles).

C-MPR Related:

NOx SO2 Hg and other common pollutants excluding PM

Due to the unique properties of our absorption liquid we are able to separated acids by a very simple process using minimum extraction steps.

The concentrated H2SO4 (40%) contains less of 1% impurity and the nitrate fertilizer can be solidified as a pure KNO3 salt that is pure above 99.5 %.

Because of a stable complex and equilibrium between phases, the metals are locked within the absorption liquid and do not leach into the aqua phase.
