Frequently Asked Questions

The C-HgR™ is a singular solution that is custom made and installed as a retrofit.

Our unique absorption process efficiently removes mercury emitted in flue gas streams regardless of its industrial applications and sources. The solution is completely scalable and can be applied to various industrial plants and processes emitting Hg regardless of flue gas flow rate and mercury concentrations in the gas being emitted.

No, it is by no means dangerous when used for industrial purposes. Our C-HgR™ unique absorbent liquid is based on ionic liquid – a new type of solvent which is safe and currently used in many industrial processes & chemical /gas absorption processes today.

Our solution does not produce any waste or contaminated byproducts besides the very small amounts of mercury that are separated and stabilized as mercury sulfide (“Cinnabar”, HgS) for safe disposal (unlike most commonly used solutions).

The amount of mercury that can be captured in our unique liquid can reach up to 1:1 by weight. However, the actual operational mercury load to 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.

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

No negative effect of SO2/SO3 has presented itself during research, trials and operational pilot. Therefore, the negative effect on liquid performance is not to be expected.

The chemical process is handling metallic and ionic Hg (as these are the major ones in the flue gas at high temperature), as well as mercury compounds (absorbed onto the surface of other particles).

The mercury is in a form of oxidized mercury salt which is in a stable complex as part of our absorbent liquid. Following the regeneration process which is performed offsite, the mercury is separated and received as stabilized HgS. It is then ready for disposal (in small quantities) while the absorbent liquid is regenerated for reuse (which is a part of the service we provide our customers).

In terms of composition, the flue gas comes out of our system as it entered (without the Hg obviously), meaning that no negative influences should come as a result.

The only impact of our process on the flue gas properties is the temperature – coming out of our system at 100-140°C (on average).
