Fluid Catalytic Cracking - improve productivity and plan maintenance efficiently

Tracerco can help you understand catalyst and process flow behaviour inside your Fluid Catalytic Cracking (FCC) unit, so you can improve productivity, identify problems and plan maintenance efficiently.

Using a Tru-Scan™, we can measure the height of the catalyst level in the reactor or regenerator. This can help you recalibrate your level instruments and run the unit efficiently.

A Tru-Scan™ is also used to measure the catalyst level in the primary cyclone diplegs in the reactor or regenerator.  Using a ThruVision™ scan, Tracerco can provide you with a detailed picture of what’s happening inside the riser. The scan produces a detailed cross-sectional density profile, to help you identify problems including catalyst maldistribution from plugged or fouled nozzles.

Using tracers, we can measure vapour flow patterns in key places throughout the FCC. This provides you with accurate information on velocity, distribution, and residence time, allowing you to fine tune your operations and troubleshoot problems. Alongside measuring hydrocarbon flow, our proven tracer studies can be used to improve efficiency by analysing the flow of the stripping steam and combustion air within the regenerator.

Adding a vapour tracer to the combustion air in the regenerator means we can identify maldistribution from the air grid and to the cyclones, as well as calculate its superficial vapour velocity up the regenerator, and residence time.

Our catalyst tracer studies give you an in-depth understanding of operational and mechanical issues in your unit, including calculating important metrics like the slip factor. We can measure the catalyst velocity, distribution, and residence time in the reactor, riser, and stripper.

In the same way, by using a tracer and detectors in the regenerator, we can work out the residence time of the spent catalyst, as well as the catalyst distribution at the bed level and the primary cyclone inlets.
