||The report gives results of a small pilot-scale evaluation of the E-SOx process, undertaken to obtain information needed to conduct a planned 5 MWe field pilot demonstration. The process uses an electrostatic precipitator (ESP) for combined sulfur dioxide (SO2) removal and particulate collection. The concept of spray drying is introduced to the inlet and/or first section of the ESP in which electrical components are removed. Because of the many ESPs at coal-fired power plants, the process is well suited to retrofitting. Evaluation results indicate that a 50-60% SO2 removal at a calcium/sulfur ratio of 1.2-1.4 can be obtained. Furthermore, this SO2 reduction can be achieved without degrading the particulate emissions event though the process requires a reduction in the collecting surface of the ESP. The use of a temperature-controlled electrode precharger to compensate for collecting surface loss is also described.
