Document Type and Number:
Japanese Patent JP2972923
Kind Code:
B2
Abstract:
The system for treating effluent water coming out from the desalter in accordance with the present invention comprises a slop oil separator 1 for removing oil components in the effluent water from the desalter; a WSR separator 2 for further removing emulsion type oil components using naphtha; a water stripper 4 for removing gas components such as H2S and NH3 in the effluent water discharged from the WSR separator; a reaction tank 5 for reacting organic and/or inorganic impurity matters such as phenols and suspended solids in the effluent water discharged from the water stripper with activated charcoal; and a settling tank 6 in which an agglomerating agent is introduced, thereby precipitating sludge in the lower part of the settling tank. A buffering tank 3 may be installed between a desalter (not shown in FIG. 1) and an oil separator 1 or between a WSR separator 2 and a water stripper 4 to play a role as a buffer for safety in case of an accident in the process. Activated charcoal is introduced into the reaction tank 5. An agitator 14 is installed to mix physically the effluent water containing activated charcoal in the reaction tank. Alternatively, an air supply device 15 is installed to mix the effluent water containing an activated charcoal by supplying air into the reaction tank.
