Tracerco PhaseFinder™

What type of services does Tracerco provide for desalters and what does it reveal? A Tracerco PhaseFinder™ scan of a desalter measures interface levels through the vessel wall between liquid and solids, or between two different types of liquids. A PhaseFinder™ scan of desalter vessels will yield a lot of information about where the various layers of material are located, and the quality of interface between oil and water.

A tracer study can be used to measure the oil and water phase residence times through a desalter vessel, and detect the presence of oil carry-under or water carry-over. visualise fluid flow through the reservoir, and enhance their understanding of reservoir connectivity. Smart interwell tracers provide direct measurement of remaining oil in the reservoir, allowing a better understanding of EOR program effectiveness.

What preparation is needed to the desalter before Tracerco’s services are performed? PhaseFinder™ is generally performed without any preparation to the vessel, but in some cases, a small 25cm (10in) strip of insulation may need to be removed. A Tracerco crew will need access to the vessel, or above the section to be surveyed, either by ladders to the platform, scaffolding or a crane basket. Our PhaseFinder™ equipment is very lightweight and portable. Tracer studies performed on desalters require a suitable injection point on the water or oil inlets, into which a pulse of oil or water phase tracer can be injected.

Tracerco Diagnostics™ Distribution study - FCC stripper

Uniform distribution of catalyst and steam in a stripper is critical to achieve high stripping efficiency (less carry-down of hydrocarbon products from reactor to regenerator). A failure to effectively remove hydrocarbon from the catalyst will result in a loss of product, lower throughput, and lower ...
