The performance of a three-stage mist collector has been investigated through parallel tests in the laboratory and at a transmission plant over the course of one year. Collection efficiency, loading, and pressure drop were measured repeatedly over time for the entire collector and for each of its three component stages. The first-stage, metal mesh filter maintained constant performance over the year, both in the lab and in the plant. The second-stage, pocket filter decreased substantially in efficiency over time, particularly for sub-micrometer droplets; this decrease paralleled an increase in pressure drop and loading. The third-stage, 95% DOP filter maintained high efficiency and low pressure drop in the lab; however, the corresponding filter in the plant decreased in efficiency as loading and pressure drop increased. These data suggest how well mist collectors perform under ideal as well as practical conditions, and can help establish maintenance guidelines that keep performance high.
