Selective Catalitic Reduction (SCR) Replacement Project
1. HDP arrays can replace multiple systems
Common gaseous pollutants in flue gases are sulfur oxide, nitrogen oxides and carbon dioxide. The first two are responsible for acid rains and smog while the third is the cause of global climate change. The comparison of current technology with the high density photobioreactor (HDP) is given in Table 1 .
2. HDP is more cost-effective than selective catalytic reduction (SCR) system
Table 2 shows the comparison of the cost to remove nitrogen oxides using HDP arrays and SCR in an example power plant. The third column shows savings in green .
3. HDP provides a complete solution
HDP arrays can remove carbon dioxide, along with nitrogen oxides and sulfur oxide at low costs. HDP arrays can delieve significant savings on per ton bases. Table 3 shows the comparison of costs of removing nitrogen oxides and carbon dioxide using HDP arrays to costs of removing nitrogen oxides using SCR .
4. HDP protects the environment
HDP operates at normal conditions without chemicals where SCR may cause significant environmental impacts. The detailed comparison is given in Table 4 .
We are looking for partners to showcase the HDP technology in power plants.
