Conventional technology for injection of
demulsifying
chemicals are nozzles and injection quills. As it is very difficult to make sure that the demulsifying agent arrives at the droplet surfaces that is dispersed in the continuous oil stream, overdosing of chemical can become a problem. Instead of destabilizing an emulsion, a new emulsion can be formed, resulting in malfunction of the oil-water separator.
The ProPure mixing technology has been applied successfully to safeguard that the demulsifying agent is injected and mixed homogeneously in the continuous phase, such that new surface area for droplet – droplet coalescence is created. With careful re-mixing (at typical pressure drops less than 0.1 bar) the injected chemical can reach the new surface area of the droplets, and immediate and effective water droplet coalescence can commence.
The successful implementation of ProPure mixing technology for de-watering shows a large potential also for desalting of crude.
Special features of this product is the following:
Lower chemical consumption / Reduced environmental impact
Improved oil-water separation performance
Smaller size of gravitational oil-water settler or electrostatic coalescer
