摘要： To efficiently separate water containing components originating from coal tar or crude oil and forming an o/w emulsion, such as ammonia-containing wastewater from a coke oven of an ironworks or wastewater from an atmospheric distillation unit, an FCC unit, an RFCC unit, or a desalter of an oil refinery, into oil and water. A method for separating an o/w emulsion into oil and water includes adding a phenolic resin to an o/w emulsion including a component originating from coal tar and/or crude oil. A coagulant is preferably further added to the o/w emulsion. An organic coagulant is particularly preferable. It is possible to efficiently separate the o/w emulsion into oil and water in a short time to produce treated water in which the amount of oil components has been reduced. Since a phenolic resin is not an inorganic substance, reusing separated oil components including the phenolic resin does not impose any problem.

摘要： A remote submerged chain conveyor system for separating particles from a coal ash/water slurry from one or more remotely located boiler units. A tank forms an ash holding section, a dewatering section, and an ash settling section. The ash holding section receiving the slurry with first and second opposite ends. The dewatering section dewaters the slurry. The settling zone is an elongated trough connected with the ash holding section at one end with a discharge drain trough at near an opposite end. The tank sections being oriented in a generally linear arrangement wherein a net flow of water from the ash/water slurry is in a direction from the settling zone toward the distal and. A drag chain moves along the ash settling conveying the particles settling from the slurry to the dewatering section.
