Cansolv offers a unique approach to the hurdle of FGD 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 reducing 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.
As the developed and developing countries alike continue to thrive and as global population increases, the power sector is faced with two central yet somewhat contradicting challenges:
- Reducing their harmful emissions
- Adjusting production to the rapidly increasing energy demand
Complicating the paradox, 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 continue to generate electricity; while still being required to meet their strict environmental SO2 emission 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:
- High reagent and associated transportation costs
- Complications of storage and handling of reagent and waste product (gypsum)
- Constrained liquid effluent regulations
Carbon dioxide capture and storage and GHG abatement
Tackling climate change through mandated greenhouse gas abatement continues to be a topic of focus in looming legislation for electricity generators using fossil fuels. Efficiency improvements to existing plants continue to be the ‘low hanging fruit’ to meet this challenge; however, they can only go so far. Supplemental actions need to be taken if the world wishes to meet aggressive GHG abatement targets. One such option for further CO2 reductions is through the application of carbon capture and storage (CCS).
