This guide is intended to assist knowledgeable personnel with sizing a highland tank oil water separator.
Oil droplets from 20 to 150 microns in diameter.
The information contained herein is the opinion of highland tank.
The name is derived from the fact that such separators are designed according to standards published by the american petroleum.
This design also known as an api separator generally provides a discharge oil concentration of 100 ppm based on a 150 micron droplet size.
An api oil water separator is a device designed to separate gross amounts of oil and suspended solids from the wastewater effluents of oil refineries petrochemical plants chemical plants natural gas processing plants and other industrial oily water sources.
This correlates to a tank size that can be 5 times the size of an equally sized coalescing separator.
Below is a sample shot of the spreadsheet.
See figure 5 33 and figure 5 34.
The spreadsheet operates on microsoft excel 2003 or later.
This correlates to a tank size that can be 5 times the size of an equally sized coalescing separator.
When sizing an ows there are three primary factors to consider.
