Optimize extra heavy/ heavy crude separation

Get better process control

In extra heavy and heavy crude oil separation (< API 15 Density >960 kg/m3 (8 lb/gal) and oil sands, the cleaning process is done in separators, FWKO, BOTs and Desalters. It is important to know the density over the entire level to ensure the most time and cost-effective operation. Traditional measurement technologies are limited in the information they can provide about the process. Profile Vision gives a clear view to the process.

Benefits at a glance

  • Precise 3-dimensional density profile of the entire separator - from inlet to outlet

  • Installation is completely outside of the vessel

  • Separation is not interrupted for density related issues

  • No more under/overdosing of expensive chemicals to the process

Challenge: getting a complete view to your process

Traditional technologies are not able to give clear view of the overall level and the emulsion layer. The position and thickness of the emulsion layer is important information to have, as it determines the amount of chemical emulsion breakers that must be added. Traditional measurement technologies must be installed inside the separator and are often susceptible to contamination. So the measurement device must be removed for cleaning on a regular basis - which is valuable time wasted.

Our solution: density profiling system

Separator is divided into 3 density detection areas:

  • Measure presence of sand at the bottom to ensure that entire volume of separator is available

  • Measure emulsion layer and thickness to optimize your separation process and save costs related to under/over dosing of chemicals

  • Clean crude at the top is monitored. Integrated PLC collects and scales all measurement data. Visualization of up to 5 different interface levels is possible (sand, water, emulsion, oil, and foam).
