Radiometric measurements deliver ROI, sustainability

As refiners continue seeking ways to maximise efficiency, minimise downtime, and improve sustainability, radiometric multiphase level measurement system comes as a game-changer

- 

IN today's competitive oil and gas landscape, process optimisation, equipment reliability, and sustainability are critical for maintaining profitability.

Among the many challenges refiners face, monitoring separation processes effectively is particularly complex yet essential.

Multiphase level measurement technologies, especially nuclear density profiling systems like Berthold's EmulsionSENS, provide superior reliability, performance, and environmental benefits.

THE SEPARATION CHALLENGE

Separation processes are vital across oil and gas operations from separators and storage tanks to desalters and alkylation units.

In desalters, for example, ensuring a clear distinction between the oil, water, and emulsion layers is critical to prevent salt and water carryover, which can cause corrosion and fouling in downstream equipment.

Additionally, the occurrence of rag layers stubborn, semi-stable emulsions that resist separation can further complicate the process.

Without proper monitoring, these rag layers can lead to inefficiencies, increased chemical consumption, and potential process upsets.

Measurement technologies fall into two categories: Direct and indirect methods. Direct methods like differential pressure and RF absorption physically contact process fluids but struggle with emulsion height changes and buildup interference.

Indirect methods, such as nuclear density profiling systems, offer more reliable monitoring under challenging conditions.

NUCLEAR DENSITY PROFILING: HOW IT WORKS

Radiometric measurements employ a simple yet sophisticated principle radiation attenuation.

A typical system consists of a radioactive source and detector positioned on opposite sides of the vessel.

As gamma radiation from the source penetrates the vessel and its contents, the radiation intensity decreases based on the density of the materials it passes through.
