  "text": "Technique\nDescription\nElectrostatic precipitator (ESP)\nElectrostatic precipitators operate such that particles are charged and separated under the influence of an electrical field. Electrostatic precipitators are capable of operating under a wide range of conditions.\nAbatement efficiency may depend on the number of fields, residence time (size), catalyst properties and upstream particles removal devices.\nAt FCC units, 3-field ESPs and 4-field ESPs are commonly used.\nESPs may be used on a dry mode or with ammonia injection to improve the particle collection.\nFor the calcining of green coke, the ESP capture efficiency may be reduced due to the difficulty for coke particles to be electrically charged\nMultistage cyclone separators\nCyclonic collection device or system installed following the two stages of cyclones. Generally known as a third stage separator, common configuration consists of a single vessel containing many conventional cyclones or improved swirl-tube technology. For FCC, performance mainly depends on the particle concentration and size distribution of the catalyst fines downstream of the regenerator internal cyclones\nCentrifugal washers\nCentrifugal washers combine the cyclone principle and an intensive contact with water e.g. venturi washer\nThird stage blowback filter\nReverse flow (blowback) ceramic or sintered metal filters where, after retention at the surface as a cake, the solids are dislodged by initiating a reverse flow. The dislodged solids are then purged from the filter system",
