Phase Mixers, Blenders, and Reactors

Where possible, agitators should be covered with sufficient depth of liquid to minimize splashing, or operated at a reduced speed until sufficient depth has been built up. In cases where hazardous static accumulation in the 

Since static discharges frequently occur at the liquid interface as liquid drains from the wetted wall, a vapor ignition hazard may also exist [ 157,159]. These discharges may be either brush types or PBDs (2-6.2 and 2-6.5). In 1997 it was concluded that Manufacturers have so far not paid attention to requests by the operators of enamel apparatus for a coating which is completely or partially capable of dissipation [159]. However, this situation is believed to be changing and it might now be possible to specify special static dissipative coatings for the vessel and stirrer.
