    • The present invention relates to a fly ash utilization process or system for the removal of sulfur dioxide from the flue gas of coal fired boilers.
      In one embodiment, a high ionic concentration is maintained in a closed loop, water balanced system which is operated at a low pH, i.e. less than 4 and preferably less than 3. The ionic concentration of the scrubber slurry is maintained at at least 5,000 parts per million of alkali metal cations, preferably over 10,000 parts per million, at least a substantial portion of which has been leached from fly ash.
      The ionic concentration of the scrubber slurry is maintained at a high level by providing small diked areas (38, 42) in a waste pond (34) for settling of undissolved solids wherein the returned supernatant has a high ionic concentration.
      A principal advantage of the system is that there is a substantially reduced liquid-to-gas ratio required for scrubbing SO 2 , with substantial savings in pumping and power requirements for the system.

    • A process for steam stripping sulfur dioxide from a buffered aqueous solution in which it is absorbed in a flue gas desulfurization process is carried out at pressure greater than atmospheric. The process of pressure stripping of sulfur dioxide surprisingly results in increased steam economy as compared to stripping at atmospheric pressure and yields sulfur dioxide vapor which can be directly condensed to a liquid product with ordinary cooling water, eliminating the need for drying, refrigeration or compression operations. The high temperatures corresponding to high steam pressures enable economical use of stripping vessel overheads for preheating operations also. Stripping at pressures of 50 to 65 psig results in steam requirements which are only one-third to one-half of that at atmospheric pressure stripping. At the high pressures lower gas flow rates permit the use of more compact stripping equipment.
    • 从其中被吸收在烟道气脱硫过程中的缓冲水溶液蒸汽汽提二氧化硫的方法在大于大气压的压力下进行。 二氧化硫的压力剥离过程令人惊奇地导致蒸汽经济性与在大气压下的汽提相比增加,并产生二氧化硫蒸气,其可以用普通冷却水直接冷凝成液体产物,从而不需要干燥,制冷或压缩操作 。 对应于高蒸汽压力的高温也可以经济地使用汽提塔顶部进行预热操作。 在50至65psig的压力下汽提,导致蒸汽需求量,仅为大气压力汽提时的三分之一至二分之一。 在高压下,较低的气体流量允许使用更紧凑的剥离设备。
