SCALE CONTROL IN FLUE GAS DESULFURIZATION |
| 摘要 |
<p>An improvement in a process for flue gas desulfurization in which new polymers which are the reaction product of N-aminoethylpiperazine and a dihalo or epoxyhalo compound, which are subsequently phosphonomethylated, are employed as threshold agents, prevent calcium scale formation in the contacting section but permit precipitation of calcium compounds at a later stage.</p> |
