Incorrect Design of Process Units

4 Some Typical Reasons for Environmental Pollution 7.4.1 Incorrect Design of Process Units [Pg.123]

Incorrect design of equipment (such as reactors, heat exchangers, condensers, coolers, grinders, dust collectors) which may cause incomplete conversions, inefflcient heat transfer, and escape of volatile products or particulate matters. Converters with too small diameter or absorbers with too less height have very less residence time for gases and can lead to inefficient operations. [Pg.123]

Inefficient internals (less active catalyst and improper type of tower packing cannot ensure gas-liquid contact, a tilted distributor tray which will not irrigate [Pg.123]

Not incorporating a filtration system for raw materials can partially mask the active surface of catalyst due to deposit of dust (which can affect conversion efficiency)  [Pg.124]

Likely by passing of catalyst beds if a proper gas distributor is not provided in the converter at entry point of the bed  [Pg.124]
