Measuring the interfaces of oil / emulsions / water in desalters

Measuring the interface levels of oil / emulsions / water in desalters and separators

To ensure extracted brine is free of oil and water does not contact the electrostatic grid or enter the oil outlet, the different levels have to be controlled carefully. The Berthold Multiphase Level Measurement system - EmulsionSENS is used to reliably monitor the separation process online. With two different arrangements, either the product density at specific heights (aligned arrangement) or the level of different phases can be measured continuously (staggered arrangement). Suited for all API oil grades – even for heavy and extra heavy crudes – the measurement is repeatable and stable over time, with no need for cleaning or recalibration.

Optimum control of the desalting process

To ensure optimum control of water / emulsions / oil separation layers in the desalter, more and more operators are turning to radiometry as a highly reliable and accurate measurement solution. By optimizing the process, you minimize the probability of failure, increase efficiency, reduce emulsion breaker chemicals and thus permanently reduce your operating costs.
Thus, we reduce the probability of upsets for our customers and maximize throughput in the desalter. This process optimization saves money in the long term. According to customers and experts, these are savings of $100,000 to $300,000. We help you to optimize your processes. We offer you tailored measurement solutions that meet the requirements of the refinery with the highest degree of accuracy and stability.

Detector retrofit program to improve your production

Especially in low radiation conditions, our highly sensitive detectors improve the signal to noise ratio, what is resulting in superior measurement performance compared to competing systems. Source replacement is costly, time consuming, and does not work towards a reduction in overall site source activity.
