Description

DEVA DEM-SERIES is a complex blend active agents and wetting agents designed to migrate to the oil/water interface inorder to rapidly break any emulsion to give clean oil and clean water.

Application

DEVADEM-SERIES should be injected using a chemical proportionating pump into the fluid to be treated at a point as far as possible upstream of the dehydrators or desalters.

For dehydration when heat is employed the dosage tends to be about 10ppm for most applications, there are however occasions when this treating ratio may have to be adjusted either in the upward or downward direction depending upon the nature and tenacity of the emulsions.

For desalting using electrostatic precipitators the dosage will be in the range of 1ppm to 5ppm.

Treatment dosage rates depends on several factors such as:-

  • Type of emulsion
  • Degree of agitation in the system.
  • The Gas/Oil/Water ratios.
  • Treating temperature
  • Residence or coalescence time
  • Quality of wash water (for desalting applications)
  • Design features of the dehydrator/desalter.

Typical dosage would vary between 10ppm-150ppm depending on the above mentioned factors.
