With the dwindling supply of low sulfur content fuel, power generators will soon face the dilemma of switching to a higher sulfur content fuel in order to generate electricity; while still being required to meet their strict environmental SO₂ emissions restrictions. Historically, non-regenerable  alkali scrubbing processes (such as caustic, limestone and lime) have been applied in these Flue Gas Desulfurization (FGD) applications.  However, in recent years, this process has subjected utility companies to several growing legacy challenges, for example: 

Cansolv offers a unique approach to the FGD hurdle in the form of a regenerable absorption technology that allows the use of high sulfur, low value fuels while still meeting the most stringent of environmental requirements and reduces the challenging legacy obligations. Once removed by Cansolv, the by-product of pure SO₂ gas can be converted to a marketable commodity such as sulfuric acid or sulfur.

In addition, this system can be combined with our CO₂ post-combustion capture system for carbon capture for Enhanced Oil Recovery (EOR) or sequestration (CCS) for greenhouse gas emissions compliance.
