Api For Oil Removal

-

 

An API oil-water separator is a device designed to separate gross amounts of oil and suspended solids from the wastewater effluents of petroleum refineries, petrochemical and chemical plants, natural gas processing plants and other industrial sources.

 The name is derived from the fact that such separators are designed according to standards published by the American Petroleum Institute (API).

 The API separator was developed about 75 years ago by the API and the Rex Chain Belt Company. The API separator is normally the first, and most important, wastewater treatment step in petroleum refineries. The primary function of a properly designed API separator is to remove the majority of oil and suspended solids from refinery wastewater prior to subsequent downstream wastewater treatment processes.

Krofta is a leading source for API Separator design, engineering, and manufacturing services. A well-designed, properly functioning API Separator is a tremendous piece of wastewater process equipment for refineries, chemical plants, power plants, and many other heavy-duty industrial facilities. They are designed per American Petroleum Institute standards (API) for above and below ground installations.

A gravity differential settling is used to separate the oil from water. Krofta engineers will evaluate the type and state of the oil and the characteristics of the waste stream to determine the proper design and size of the separator. Oil globule size, specific gravity of the oil and wastewater, temperature, and viscosity should be considered. Suspended solids will also be settled from the wastewater and provisions of this will be part of the design.

The API separator works on the principle of Stokes Law, which defines the rise velocity of an oil particle based on its density and size. Typically, the difference between the specific gravity of oil to be separated and water is much closer than the specific gravity of the suspended solids and water.

Don't guess on the sizing------call us. We do this every day.

Tannery Wastewater Treatment

-
Image
  Tannery wastewaters  are highly complex and its treatment is administered by physical or chemical or biological or a combination of those methods. From the review, it is often concluded that physical/chemical processes combined with the organic process is the better option for the treatment of tannery wastewater. The tanning industry is one of the oldest industries on the planet and therefore the problem of treatment and disposal of those wastes is perhaps as old because of the industry itself.  Tanneries wastewater  effluent is treated in many various ways. There are situations during which a private tannery applies all the below-described  wastewater treatment  steps on site. In other situations a private tannery may apply (on-site) only pre-treatment or a neighborhood pre-treatment or no treatment in the least, sending the effluent to a centralized effluent treatment plant. Nevertheless, treatment is important thanks to the wide selection of toxic effe...
